Technical Field
[0001] The present invention relates to a preparation for the simultaneous treatment of coccidiosis and iron deficiency, comprising a triazinone such as torul ziril and a polynuclear iron(III) polysaccharide complex compound together with a specially selected surfactant.
[0002] Economically successful meat production operations are currently characterized by highly intensive rearing, i.e., rearing a large number of animals specially selected to optimize breeding purposes . These farms are characterized, for example, by the use of large amounts of machinery, additional feeding of nutritional supplements, and involvement of as few staff as possible. In the case of a piglet rearing farm, this means rearing a large number of female pigs that are bred to increase the litter size of piglets in a pigsty of appropriate size . By optimizing the feed and making appropriate selections during the rearing process, rapid growth of piglets is enabled. This type of animal rearing often causes an increase in certain typical diseases and deficiencies. Especially
[0003] in addition to the stress to which intensively reared pigs are very susceptible, such phenomena are especially protozoal infections (coccidiosis) and anemia in young pigs, and both of these must be pre-controlled by the prophylactic use of drugs.
[0004] Coccidiosis is a parasitic infection that frequently occurs in animals. For example, the genus Eimeria (Eimeria), the genus Isospora, the genus Neosp ora, the genus Sarcosporidia, and Toxoplas Protozoa of the genus Toxoplasma cause coccidiosis worldwide. An economically significant example of coccidiosis is the disease of pigs caused by coccidia of the genus Isospora. An infectious disease, or a bovine infection caused by coccidia of the genus Eimeria. (Isospora) In recent years, infection with Isospora suis has been recognized as a cause of diarrhea in piglets. This is being studied intensively. In principle, the infection is transmitted from the environment to the piglets, or from the piglets. The process progresses from the piglets through oocysts, and each oocyst is different in each case. It contains two sporocysts, each having two sporozoites. The parasitic stage is the small intestinal villi. It proliferates in epithelial cells. The clinical presentation of this disease includes necrosis of intestinal epithelial cells accompanied by atrophy of the villi and inflammation. It involves chemical damage, resulting in impaired absorption and digestion. A characteristic of acute illness is a liquid, whitish substance. The diarrhea is a light yellow to yellowish color and mainly occurs in piglets 2-3 weeks after birth. Weight gain decreases. To date, treatment and therapy for this disease have been inadequate.
[0005] Antibiotics are ineffective, and sulfonamides are approved for the treatment of coccidiosis, Its effectiveness is questionable, and in any case, frequent repeated administration is unsuitable for practical use. Other possibilities The treatment is questionable, for example, the administration of monensin, amprolium, and furazolidone. We have not been successful in preventing the disease in experimentally infected piglets. More recent research suggests that Isosu Despite good hygiene conditions, Isospora suis It has been observed in up to 92% of all littermates on the farm. This type of disease affects not only pigs. , and many other animal species, such as poultry, calves, lambs, or small animals (rabbits) This also occurs.
[0006] An example of deficiency is iron deficiency in newborn piglets. Due to rapid growth in the first few days of life, the body... Stored iron is rapidly depleted and must be replenished by external sources. Because of the large number of tadpoles, consuming sow milk is not sufficient to adequately substitute for this. This is not possible. Furthermore, if the animals are kept in concrete or plastic, Piglets cannot dig in the ground to absorb iron compounds. They become anemic.
[0007] When the hemoglobin content in the blood falls below 80 g / L, it indicates a clinically significant state of anemia. Appears. NRC recommendation (National Research Council, Nutr ient Requirements of Domestic Animals,No .6,Nutrient Requirements of Swine,Nation al Academy of Sciences,Washington DC,197 9) 90 g / m² is the minimum hemoglobin level at which piglets grow healthily and show no signs of anemia. L is specified. However, significant symptoms such as weight loss and stunted growth are present in the hemoglobin in the blood. This is only observed when the globin content drops to a value of less than 80 g / L. (Regarding iron supply) Other indicators include hematocrit and red blood cell count per unit volume. Severe iron deficiency Sexual anemia also leads to the death of young piglets.
[0008] Medications to control the aforementioned diseases and deficiencies are already available.
[0009] Coccidiosis can be effectively controlled by administering the active ingredients of the triazinon group. This is possible. For this purpose, triazinedione (a representative example is the active ingredient class clazuril, diclazuril, retazuril) is distinguished from triazinetrione containing the active ingredients toltrazuril, toltrazuril sulfoxide and ponazuril. Triazines, especially toltrazuril, ponazuril or diclazuril, and their activity against coccidia are known from a series of publications, and in particular, see German Patent Application Publication No. 2718799 (DE-A 27 18 799) and German Patent Application Publication No. 2413722 (DE-A 24 137 22). International Publication No. 99 / 62519 (WO99 / 62519) discloses a semi-solid aqueous preparation of toltrazuril sulfone (ponazuril). In particular, toltrazuril is also known to be suitable for the treatment of coccidiosis in pigs (e.g., Isospora suis).
[0010] International Publication No. 99 / 62519 (WO99 / 62519) discloses a semi-solid aqueous preparation of toltrazuril sulfone (ponazuril). In particular, toltrazuril is also known to be suitable for the treatment of coccidiosis in pigs (e.g., Isospora suis). It is also known to be suitable for the treatment of coccidiosis in pigs (e.g., Isospora suis). It is also known to be suitable for the treatment of coccidiosis in pigs (e.g., Isospora suis).
[0011] The most important products in the market for the treatment of coccidiosis are diclazuril for use in mixtures in feed (2,6-dichloro-α-(4-chlorophenyl)-4-(4,5-dihydro -3,5-dioxo-1,2,4-triazin-2(3H)-yl)benzeneacetonitrile ; CAS No. [101831-37-2]) and toltrazuril (1-methyl-3 -[3-methyl-4-[4-[(trifluoromethyl)thio]phenoxy]phenyl]- 1,3,5-triazine-2,4,6(1H,3H,5H)trione; CAS number 690 04-03-1).
[0012] Toltrazuril is used, for example, as a drinking water preparation for poultry, and especially for suckling pigs. Several commercially available oral suspension formulations for therapeutic use are available. For piglets, raw... It is recommended to administer 20 mg / kg body weight 3 to 5 days later.
[0013] The general concept of combining active substances with iron compounds for the treatment of coccidiosis. This is also known.
[0014] As a best example, see European Patent Application Publication No. 2164496 (EP 2 164 4 96 A1) is intended for use in the simultaneous treatment of coccidious infections and iron deficiency. Disclosure of formulations containing triazinones such as trazuril and polynuclear iron(III) complex compounds. And regarding the clinical goal of weight gain in piglet treatment with such combinations of formulations... The two compounds exhibit a synergistic effect.
[0015] European Patent Application Publication No. 2164496 (EP 2 164 496 A1) is, We discovered a formulation that can be constructed primarily from triazinon and the aforementioned polynuclear iron(III) complex compound. This also shows that it is not easy.
[0016] See European Patent Application Publication No. 2164496 (EP 2 164 496 A1) The positive correlation is described in International Publication No. 2014 / 086958 (WO 2014 / 08695 8A1) and International Publication No. 2014 / 086959 (WO 2014 / 086959A It is used for injection purposes as disclosed in 1).
[0017] The above is the specification of European Patent Application Publication No. 2164496 (EP 2 164 496 A1 ), International Publication No. 2014 / 086958 (WO 2014 / 086958A1) and International Publication No. 2014 / 086959 (WO 2014 / 086959A1) is entirely: In particular, the poly-β-FeO(OH) type iron(III) is complex-bonded polymerized into carbohydrates. To be used in combination with other substances. European Patent Application Publication No. 2164496 (EP 2 164 In 496 A1), such polynuclear iron(III) complex compounds are used as triazine compounds. In situations where these compounds are combined, it has been shown that polynuclear iron(III) polysaccharide complex compounds should be prioritized. It was done.
[0018] Its commercial importance is not monopolistic, but mainly iron(III) dextran (CAS No. 9004-66-4), iron(III) hydroxide polymaltose (iron(III) hydroxide dextrose Tran; CAS No. 53858-86-9), Iron(III) Sucrose (Iron(III) ) Sucrose, iron(III) "sugar" (CAS No. 8047-67-4) and sucrose Sodium gluconate / iron(III) complex in solution (CAS No. 34089-81 -1) is obtained by
[0019] The literature reveals different names for these compounds. In this context, Grep Toferon, iron(III) dextran, iron(III) polymaltose, iron(III) Chistrin, iron(III) sucrose, iron(III) gluconate, iron(III) sugar, etc. The compound consists of iron(3+) ions, hydroxide ions (OH-), water (H2O), and oxygen. It means a complex with (O), and these complexes exist in the form of oligomers or polymers, In the coordination sphere, one or more of the above-mentioned oligomers and polymer carbohydrate compounds are combined. It is understood that they are related by body shape.
[0020] This is because these compounds are iron(III) hydroxide polysaccharides or oxy-hydroxyiron(II) hydroxide polysaccharides. I) This is why they are also called polysaccharides, where polysaccharides refer to the oligomers and polymers mentioned above. Compound compounds or their derivatives, or generally oligomers or polymer carbohydrates Represents compounds from a group.
[0021] This type of polynuclear iron(III) complex is, for example, (DSKudasheva et al.) al.,“Structure of Carbohydrate-bound Po lynuclear Oxyhydroxide Nanoparticles in Parenteral Formulation”, J. Inorg.Bioche m.98(2004)1757-1769, similarly I.Erni et al., “Ch chemical characterization of Iron(III) Hyd roxide-Dextrin Complexes”Arzneim.-Forsch . / Drug Res. 34(II)(1984)1555-1559;F. Fun k et al., “Physical and Chemical Charact erization of Therapeutic Iron Containing Materials”,Hyperfine Interactions 136 ( 2001) 73-95;E. London “The Molecular For mula and Proposed Structure of the Iron- Dextran Complex, IMFERON”, J.Pharm. Sci. 9 3 (2004) 1838–1846 and A. John “Neue Mo:gli” neugeborene r Ferkel unter Beachtung biochemischer A spekte”[Novel possibilities of supplying iron to new born piglets,taking account of biochemical aspects], Tra:chtigkeit u nd Geburt beim Schwein [Pregnancy and bi rth in pigs]:8th Bernburger Biotechnolog This is described in y Workshop, Bernburg (2002) 89-94).
[0022] In many cases, the composition of these compounds is not quantitatively described and varies depending on the type of preparation. Because these can vary even within the compound, these polynuclear iron(III) polysaccharide complex compounds are relevant to those skilled in the art. This is understood to mean all complexes of the above types of known compounds.
[0023] These iron compounds are almost exclusively used in the manufacture of injectable formulations for human medicine and veterinary medicine. It is used. In veterinary medicine, small-dose formulations for oral administration are also used.
[0024] According to European Patent Application Publication No. 2164496 (EP 2 164 496 A1) When the initially disclosed triazine compound is combined with a polynuclear iron(III) complex compound... In addition to these advantages, the effectiveness and usefulness of the formulation used for the simultaneous treatment of coccidiosis and iron deficiency There are other potential parameters that could further influence sex.
[0025] For example, International Publication No. 2014 / 086960 (WO2014 / 086960 A1 ) discloses that foam formation is clearly an undesirable characteristic for any formulation. Therefore, International Publication No. 2014 / 086960 (WO2014 / 086960 A1) To avoid excessive foam formation, triazine, iron complex, and especially low HL are used. It is instructed that an aqueous suspension containing one or more surfactants having a B value should be used. .
[0026] International Publication No. 2014 / 086960 (WO2014 / 086960 A1) is other The surfactant can be used in combination with a low HLB value surfactant that can be added to each formulation. It is stated that this is possible, but International Publication No. 2014 / 086960 (WO2014 / 086960 A1) is International Publication No. 2014 / 086960 (WO2014 / 086 Except for those with a higher HLB value than those that reduce foam formation by 960 A1), The reasons and thresholds for the other surfactants in question have not been disclosed.
[0027] In the disclosure of International Publication No. 2014 / 086960 (WO2014 / 086960 A1) High HLB surfactants are any surfactants with an HLB value greater than 8, while also being foam-forming. Surfactants found to be advantageous in inhibiting surfactants have an HLB of up to 8. It is a sexual stimulant.
[0028] In conclusion, International Publication No. 2014 / 086960 (WO2014 / 086960 A 1) The surfactant is beneficial in inhibiting foam formation and has an HLB of 8 or less. They can be divided into two categories: those that have no such characteristic and those that can exist or not.
[0029] As described in International Publication No. 2014 / 086960 (WO2014 / 086960 A1) It has a high HLB and therefore does not contribute to the effect of inhibiting foam formation. The agents are polyethylene castor oil derivatives, polyoxyethylene alkyl ethers, and polyoxy Ethylene sorbitan fatty acid ester, polyoxyethylene stearate, sodium lauryl sulfate Thorium, docusate sodium, cetrimide, phospholipids, or cetylpyridin chloride Yes, that's correct.
[0030] However, such a list of surfactants with claimed high HLB values is actually To derive an actual surfactant that would have such a high HLB value on its own It is not specific enough. For example, the polyoxyethylene mentioned and disclosed above. All of the contained compounds have a sufficiently long polyoxyethylene moiety, When it is made hydrophilic, and therefore yields a higher HLB value, it has a high HLB value. It merely conforms to that restriction.
[0031] Furthermore, the disclosed phospholipids typically do not even have a calculable HLB value, and so on. If so, it is usually well below 10. This is because lecithin (which is a phospholipid) is... In document number 014 / 086960 (WO2014 / 086960 A1), low HLB and This is also why they are mentioned as both high HLB-value surfactants.
[0032] From these structures of potential high-HLB surfactants, only two specific elements are used in later examples. See International Publication No. 2014 / 086960 (WO2014 / 086960 A1) The formulation is specifically disclosed.
[0033] These are copolymer polyoxyl 35-castor oil and sodium docusate. It is a polyethylene castor oil derivative designated as such. International Publication No. 2014 / 086 Sample 960 (WO2014 / 086960 A1) shows the effect on foam formation at different time points. There are 14 specific individual formulations, and 3 others that are not specified regarding their effect on avoiding foam formation. Two explicit formulations are disclosed (page 18, lines 13-22).
[0034] Regarding the 14 illustrated formulations, Examples 4, 5, 7, and 8 are, for example, Cremoph High HLB surfactant sold as or EL (CAS 61791-12-6) The surfactant copolymer polyoxyl 35-castor oil is included as an example, and Examples 9 to 1 4 contains sodium docusate as a surfactant.
[0035] The foam formation has not been tested, International Publication No. 2014 / 086960 (WO20 Regarding the preparations specifically described on page 18 of 14 / 086960 A1), The first two contain copolymer polyoxyl 35-castor oil, and the third formulation contains docusate It is disclosed that it contains sodium.
[0036] U.S. Patent Application Publication No. 2014 / 0127320 (US 2014 / 01273 According to 20 A1), the HLB of docusate sodium is approximately 10, but Cremo According to phor EL's supplier data, HLB is 12-14.
[0037] International Publication No. 2014 / 086960 (WO2014 / ) containing docusate sodium Considering Examples 9 to 14 of 086960 A1), none of them inhibit foam formation. It does not contain surfactants with an HLB value of 8 or less, which are claimed to be the cause of this problem. It is clear that these are comparative examples.
[0038] This is because all formulations from Examples 9 to 14 show excessive foam formation (at least t=0 This is proven by the fact that it takes minutes.
[0039] Considering Examples 4, 5, 7, and 8, these formulations are SPAN 80 (CAS It has approximately 4.6 HLB (Examples 4, 5, and 8), also known as 1338-43-8). Sorbitan monooleate, or approximately 4.3-4.5 (in accordance with the prevention of intentional foaming) Propylene glycol monolaurate (CAS27194) having the HLB value of Example 7) Includes any of the following: -74-7)
[0040] Either sorbitan monooleate or propylene glycol monolaurate, These are added as surfactants having HLB values of approximately 4.6 or 4.3-4.5, respectively. Apart from the intentional effect of suppressing foam formation, copolymer poly with HLB of 12-14 Effects that may or may result from the further addition of oxyl 35-castor oil That is not mentioned.
[0041] International Publication No. 2014 / 086960 (WO2014 / 086960 A1) Another low-HLB surfactant that is claimed to be a good option is simethicone emulsion. However, the simethicone emulsion in question is published in International Publication No. 2014 / 086960 (WO In 2014 / 086960 A1), it takes ten minutes to obtain the HLB value that can be specified for it. Not specified in minutes. International Publication No. 2014 / 086960 (WO2014 / 0869 Disclosure 60 A1) also states that the simethicone emulsion is described in International Publication No. 2014 / 08 Definition of low-HLB surfactants for No. 6960 (WO2014 / 086960 A1) It is unclear whether this actually applies, but the addition of simethicone emulsion. The fact that this is beneficial in avoiding foam formation was reported in International Publication No. 2014 / 086960 (WO This is clearly instructed in 2014 / 086960 A1).
[0042] Simethicone itself is α-(trimethylsilyl)-ω-methylpoly[oxy(dimethicone) (Chillylylene) and silicon dioxide (at least WO 2014 / 086960 A1) (Regarding this) it is a mixture having an unspecified ratio of these two compounds, and is disclosed. The emulsion is also not disclosed in more detail.
[0043] α-(trimethylsilyl)-ω-methylpoly[oxy(dimethylsilylene)] and dioxide There is no indication that the solvent or dispersant in the mixture with silicon forms the emulsion. The indication is that any further additives to such an emulsion will remain an emulsion. There is no incitement. This is International Publication No. 2014 / 086960 (WO2014 / 086960 The beneficial effect of having the simethicone emulsion in a formulation conforming to A1) is, Silicon dioxide or α-(trimethylsilyl)-ω-methylpoly[oxy(dimethylsilyl) It originates not from Ren itself, but from an unknown surfactant needed to stabilize the emulsion. It means to do something.
[0044] Therefore, considering particularly Examples 9 to 14, see International Publication No. 2014 / 086960 Simethicone (emulsion) to formulations disclosed in document (WO2014 / 086960 A1) The meaning of "John's addition is preferable" remains unclear.
[0045] International Publication No. 2014 / 086960 (W) includes surfactants with an HLB value exceeding 8. The specific formulations disclosed in O2014 / 086960 A1) are, more specifically, the following: It is listed below.

[0056] Page 18 of International Publication No. 2014 / 086960 (WO2014 / 086960 A1) The three explicitly listed formulations on the page are 2.9% toltrazuril, 18.8% iron (as greptoferon), 0.3% sorbitan monooleate, 0.1 % Copolymer 15 Polyoxyl 35-Hydrogenated Castor Oil, 1.5% Sodium Chloride and Water, Alternatively, 4.2% toltrazuril, 13.5% iron (as greptoferon), 0.3% solubil Rubitan monooleate, 0.1% copolymer polyoxyl 35-castor oil, 1.5 % sodium chloride and water, or 4.2% toltrazuryl, 13.5% iron (grapefruit) (as phenol), 1% sodium chloride, 1% polyvinylpyrrolidone, 0.6% phenol 0.5% colloidal silicon dioxide, 0.1% sodium docusate, 0.1% smethicone It consists of a con emulsion and water.
[0057] International Publication No. 2014 / 086960 (WO2014 / 086960 A1) is described as follows: It is generally known that any of the formulations being used are suitable for treating coccidiosis in animals. While this information is generally disclosed, it is also disclosed that simultaneous treatment of coccidiosis and anemia is being promoted. It is not described in Examples 4, 5, 7, 8, 9-14 and 18, and simultaneously No further disclosures have been made regarding specific formulations that may be particularly suitable for therapeutic use.
[0058] Apart from the prior art described above, appropriate concurrent treatment options for coccidiosis and anemia Several issues related to the objective of providing [something] have been addressed.
[0059] More specifically, the problem of synergistic effects between triazinon compounds and iron complex compounds. This was discovered in European Patent Application Publication No. 2164496 (EP2164496A1). The issue of foam formation has been addressed, and is described in International Publication No. 2014 / 086960 (WO201 Triazinon and iron complex with HLB values less than 8, discovered in 4 / 086960 A1). This issue is addressed by adding surfactants to the compound combination.
[0060] Separately, surprisingly, European Patent Application Publication No. 2164496 (EP2 The beneficial effects observed in 164496A1) are due to certain triazinon compounds and certain iron (I II) By selecting an appropriate surfactant that promotes a synergistic effect with the complex compound. It was found that further improvements are possible.
[0061] Therefore, in the first aspect of the present invention, coccidiosis and A formulation is provided for use in the concurrent treatment of iron deficiency, and the formulation is toltrazuril or di Clazryl, polynuclear iron(III) polysaccharide complex compounds, and a small amount having an HLB value of 10 or more It contains at least one surfactant.
[0062] Any of the above prior art references include at least one with an HLB value of 10 or more This demonstrates that the addition of surfactants may be beneficial to the potency of any active substance in such formulations. I haven't done that.
[0063] It is advantageous to combine the treatments for the aforementioned anemia and coccidiosis into a single treatment. It reduces stress on animals, improves animal welfare, and reduces the labor involved in handling them on commercial farms. It reduces the need for manpower and provides economic benefits. Ultimately, European Patent Application Publication No. 2164 As first demonstrated by Specification No. 496 (EP2164496A1), This combination leads to improved weight gain in treated animals.
[0064] If a reduction in animal and environmental exposure to active substances and their metabolites can be achieved, then Furthermore, by reducing the dose without losing efficacy, the present invention can be further improved. If possible, it is even more advantageous.
[0065] In a second aspect of the present invention, coccidiosis and iron deficiency in non-human animals A formulation for use in treatment is provided. The formulation is toltrazuril or diclazuril. , polynuclear iron(III) polysaccharide complex compound, and at least one interface with an HLB value of 10 or higher Contains an activator, however, International Publication No. 2014 / 086960 (WO2014 / 08696 Excluding the formulations disclosed in Examples 4, 5, 7, and 8 of 0 A1).
[0066] In a second embodiment of the present invention, coccidiosis and iron deficiency in non-human animals Preparations for simultaneous treatment of the disease, toltrazuril or diclazuril, polynuclear iron(II) I) A polysaccharide complex compound and at least one surfactant having an HLB value of 10 or higher. (However, when using toltrazuril, the surfactant is copolymer polyoxy Preparations containing hydrogenated castor oil (excluding those containing 35-L35) are preferred.
[0067] In a third aspect of the present invention, coccidiosis and iron deficiency in non-human animals A formulation for use in treatment is provided, and the formulation is toltrazuril or diclazuril. Polynuclear iron(III) polysaccharide complex compounds, and at least one having an HLB value of 10 or more Contains surfactants, however, International Publication No. 2014 / 086960 (WO2014 / 086 Excluding the formulations disclosed in Examples 9-14 of 960 A1).
[0068] In the third aspect of the present invention, coccidiosis and iron deficiency in non-human animals Preparations for simultaneous treatment of deficiency, toltrazuril or diclazuril, polynuclear iron (I II) A polysaccharide complex compound and at least one surfactant with an HLB value of 10 or higher Preparation (however, when using toltrazuril, docusate sodium is used as the surfactant) Formulations containing (excluding) are preferred.
[0069] In a fourth aspect of the present invention, coccidiosis and iron deficiency in non-human animals A formulation for use in treatment is provided, and the formulation is toltrazuril or diclazuril. Polynuclear iron(III) polysaccharide complex compounds, and at least one having an HLB value of 10 or more Contains surfactants, International Publication No. 2014 / 086960 (WO2014 / 086960 The formulations disclosed in Examples 4, 5, 7, 8, 9-14 of A1), and International Publication No. 2 It is stated on page 18 of issue 014 / 086960 (WO2014 / 086960 A1). Excluding preparations consisting of preparations that are already in use.
[0070] As outlined above, International Publication No. 2014 / 086960 (WO2014 / 086 Formulations disclosed in 960 A1) that are excluded by that means have an HLB value of 10 or more. Unwantedly contains surfactants, but in practice, surfactants with an HLB value of less than 8 It is desirable to suppress foam formation.
[0071] In any of the above embodiments of the present invention, coccidious infections in non-human animals and Preparations for simultaneous treatment of iron deficiency, including toltrazuril or diclazuril, and polynuclear iron. (III) A compound containing a polysaccharide complex and one surfactant with an HLB value of at least 10. (However, the formulation contains 5% toltrazuril, 22.8% iron in the form of Fe(III) dextran, 0 0.2% sodium propionate, 0.2% sodium benzoate, 0.25% docusate Sodium, 0.05% simethicone emulsion USP, 30%, 10.5% propylene Glycol, 1.03% citric acid, 0.15% bentonite and to make 100% A formulation consisting of added water is preferred.
[0072] However, in the context of the present invention, the addition of the surfactant with an HLB value of 10 or more Furthermore, between toltrazuryl (or diclazuryl) and polynuclear iron(III) polysaccharide complex compounds Similarly, due to the double synergistic effect between them and surfactants with an HLB value of 10 or higher, ( It has become clear that any dose of toltrazuril (or diclazuril) may be reduced. It is.
[0073] Surprisingly, toltrazuril (or dicrazuril) is found in the HLB of 10 or higher. When administered to rats together with an surfactant, the pharmacokinetic area under the curve (AUC) and Cmax were observed. It was found that the latitudinal meter increased. The above effects on AUC and Cmax were observed in the Tor Trazuril (or diclazuril) with iron dextran or iron dextran glucohept This can also be observed when administered simultaneously with polynuclear iron(III) polysaccharide complex compounds such as nate.
[0074] Surprisingly, the unknown benefits of adding more than 10 HLB surfactants are as described above. Surfactant administration in pigs with toltrazuril or diclazuril and polynuclear iron(III) Effects on AUC and Cmax when administered in combination with sugar complex compounds. It overlaps dramatically with that.
[0075] This is because in these combination formulations, simple toltrazuril (or diclazuril) (Lu) or toltrazuril (or diclazuril) and polynuclear iron(III) polysaccharide complex compounds This offers an advantage because it shows a dramatic increase in bioavailability compared to combination formulations.
[0076] As a result, commercially available or disclosed toltrazuril (or dicrazuril) This is a combination of toltrazuril (or diclazuril) and polynuclear iron(III) polysaccharide complex compound preparations. Compared to combination therapy, a reduction in dosage may be possible.
[0077] The above advantages are independent of the route of administration. Parenteral administration (especially by injection) and Oral administration may be shown to offer the same benefits.
[0078] In the context of this invention, the HLB value is defined by the Davis method (Davies JT (1957)). ”A quantitative kinetic theory of emulsi on type,I. Physical chemistry of the emu lsifying agent",Gas / Liquid and Liquid / Li quid Interface,Proceedings of the Intern ational Congress of Surface Activity,pp. 426-38) or Griffin method (Griffin WC (1954)), "Calcu lation of HLB values of non-ionic surfac tants”,Journal of the Society of Cosmeti It is determined according to c Chemists, pp. 249-56).
[0079] Both methods compare the amount of the hydrophilic portion of the molecule considered to be a surfactant with the amount of the molecule. Based on a semi-empirical equation showing the correlation with the amount of hydrophobic portion, the hydrophilic-lipophilic balance (HL B) Correlate the value with the chemical properties of the molecule.
[0080] As far as nonionic surfactants are concerned, the HLB values are similar in both methods. It is not one. Typically, nonionic surfactants are assigned an HLB value based on the Griffin method. This is more common.
[0081] Therefore, in the context of the present invention, regarding the addition of surfactants with an HLB value of 10 or higher, The resulting deviation of HLB values between HLB values from the Ibis formula or the Griffin formula is Typically, when applied to nonionic surfactants, differences exceeding a deviation of ±1 do not occur. Therefore, it's not important.
[0082] Another type of surfactant is phospholipids. Within the above species, there are so-called zwitterionic surfactants. The herbal agent phosphatidylcholine needs to be handled individually. The HLB values for each are It depends greatly on the actual composition and purity. For example, the HLB value of crude soy lecithin is 3. Yes, the HLB value of refined soy phosphatidylcholine is approximately 7 (Gunstone FD). ,“Lipid Technologies and Applications”(1 997) See p.62, Table 10).
[0083] Each HLB value is derived empirically rather than being calculated from any of the above formulas. It appears to be something that was produced.
[0084] Therefore, any HLB value mentioned in the context of the present invention is determined by the Davis method or Griffith method. It can be derived from one of the methods or measured by other means, and therefore the value is It must be understood as a value represented by ±1. In any case, it relates to the operation of the present invention. The HLB value is published in International Publication No. 2014 / 086960 (WO2014 / 086960 It is specified that the value will not overlap with the value from A1) and will only be calculated by the Davis method, and that there will be no excess This relates to avoiding the formation of bubbles.
[0085] The present invention provides at least one interface activity having a hydrophilic-lipophilic balance (HLB) value of 10 or more. The surfactant ("high HLB value surfactant") preferably has an HLB value of 10 to 18. More preferably, it is between 10 and 16.7.
[0086] A preferred surfactant with an HLB value of 10 or higher is docusate sodium (HLB 10) Polysorbate, Copolymer Polyoxyl 35-Hydrogenated Castor Oil (HLB 12- 14) Pluronic F-68 (HLB 29) and Vitamin E TPGS (H This was selected from the list of LB 13.2).
[0087] Among polysorbates, polysorbate 20 (HLB 16.7) and polysorbate A 80 (HLB 15) is preferred.
[0088] A more preferable surfactant with an HLB value of 10 or higher is docusate sodium, poly These are selected from the lists of Solvate 20 and Polysorbate 80.
[0089] A more preferred surfactant having an HLB value of 10 or higher is polysorbate 20 and po It was selected from the list of Resolve 80.
[0090] In a more preferred embodiment of all the above aspects of the present invention, the HLB value is 10 or more. Two or more surfactants are present in the formulation.
[0091] In the more preferred embodiment described above, at least two boundaries having HLB values of 10 or more A surfactant is present in the formulation, and at least two of them are preferably polysorbate 2 The ratings are 0 (HLB 16.7) and polysorbate 80 (HLB 15).
[0092] In this context, polynuclear iron(III) polysaccharide complex compounds are referred to as oligomers or polymers. It exists within and as a complex with one or more of the above-mentioned oligomers and polymer carbohydrate compounds. Related to these coordination spheres are hydroxide ions (OH-), water groups (H2O), and oxygen (O). This is understood to mean a complex of iron(III) ions with iron(III) hydroxide.

[0158] In the particularly preferred embodiment described above, the non-human animal is preferably from birth to birth. Piglets that are 96 hours old, and more preferably between 24 and 72 hours after birth. These are piglets that are between 24 and 96 hours old. Coccidiosis is caused by cystoisospor It is caused by Cystoisospora suis.
[0159] In another embodiment, the formulation used has a molar ratio of Ca2+ to Na+ of 0 or more and 3 or less. Yes, and more preferably 0 to 1.
[0160] In another embodiment, the formulation used has a total content of CaCl2 and NaCl of 0. The value is 1% (m / V) or more and 5% (m / V) or less. Preferably, 0.5% (m / V) or more and 4% It is less than or equal to %(m / v), and more preferably between 0.9%(m / v) and 3%(m / v). That is the case.
[0161] Surprisingly, the amounts of NaCl and CaCl2 specified in the two embodiments described above It was found that its presence increases the stability of the formulation over time.
[0162] In another embodiment, the formulation contains 3500 ppm or less, preferably 2000 ppm or less. More preferably, it has a free iron content of 1000 ppm or less.
[0163] Quantitative measurement of dissolved iron ions can be performed, for example, by dialysis of the sample followed by the removal of dialyzed free iron. It can be measured by subabsorption spectroscopy (AAS) or other appropriate methods such as polarography or photometry. This can be done by [meaning].
[0164] In another embodiment, the formulation is stored at a temperature of 20°C to 40°C for 6 months, and then 35 00 ppm or less, preferably 2000 ppm or less, more preferably 1000 ppm or less It contains dissolved free iron ions.
[0165] The formulation more preferably contains these components after 12 months of storage, and after 24 months. This is even more preferable, and 36 months is most preferable. For example, the formulation is at 20°C or higher. After storage at a temperature of 40°C or below for 36 months, the free iron ion content is 3500 ppm or less. It may have.
[0166] The measured iron ion content mainly consists of two iron ion sources. The solvent of the formulation already contains It is clear that the dissolved iron ions are part of the free iron according to the present invention.
[0167] A second source of free iron is a small complex frag known in the literature as unstable iron. It is iron that exists as free iron in the form of ment. In other words, such free iron is essential Either the polysaccharide complex compound was partially or completely decomposed, or a defect occurred. As a result, it can no longer be stably bound to the polysaccharide complex.
[0168] These complex fragments can be converted to Fe2+ and / or by appropriate sample pretreatment methods. Alternatively, it is transferred to Fe3+ ions, and together with the Fe2+ and Fe3+ ions originally present in the formulation... It is measured as described above.
[0169] Therefore, within the scope of the present invention, by AAS, polarography, or photometric methods The determined iron ion content is determined by the ions that are transferred to free dissolved ions during sample preparation. In addition, it refers to the content of Fe2+ and / or Fe3+ ions that dissolve freely in the formulation. It is understood that Fe2+ ions are not directly measured, but during sample preparation or The form of Fe3+ ions that are transferred to Fe3+ by other active means and freely dissolved in Fe3+ ions Measurable free iron is generated.
[0170] Within the scope of this invention, the term "free" iron measured by the above method is thereby By overloading the iron transport capacity of the aforementioned iron transport protein, toxicity is induced after administration. It contains all possible iron compounds.
[0171] As a result, the amount of free iron measured by any of the above methods is the same as that measured by all measurement methods The method measures the total amount of free dissolved iron and its non-functional complexes, according to the above function definition. The amount of iron is always equal to or greater than the actual amount, while only a portion of it is administered. It can actually be harmful to the target.
[0172] The above-mentioned "free" iron needs to be separated from "activated iron". For the purposes of this invention, "Activated iron" refers to the amount of iron that is stably present in a polynuclear iron(III) polysaccharide complex compound. And in the context of the present invention, activated iron cannot be Fe2+, but it must be Fe3+. It must be done.
[0173] Furthermore, in the context of the present invention, a weight percentage or ratio is disclosed with respect to the activated iron. In such cases, the amount is the respective amount / weight of the complex-forming agent (i.e., polysaccharide complex). It must be considered to always be listed.
[0174] Therefore, in the context of the present invention, any formulation used and disclosed herein Any reference made to the proportion of polynuclear iron(III) polysaccharide complex compounds that are part of the above is, In the aforementioned formulation, subsequent coordination with a polysaccharide complex results in a polynuclear iron(III) polysaccharide complex compound. This should be understood as the actual amount of activated iron(III) produced. , the actual amount of polynuclear iron(III) polysaccharide complex compounds in any formulation used and disclosed This is significantly more abundant than the actual "activated iron."
[0175] The present invention is not limited to the following embodiments, but will be further described with reference to the following embodiments. It can be done. [Examples]
[0176] Prepare the formulations to be used in Examples 1-4.
[0177] The toltrazuril preparation used in Examples 1-4 below contains the required amount of toltrazuril. It is produced by measuring it into a beaker and dissolving it in about half the volume of the main solvent.
[0178] Next, if applicable, add the specified amounts of co-solvent ethanol and surfactant. Stir the formulation until a clear solution is obtained. Transfer the formulation to a volumetric flask and allow it to cool to 20°C. Heat the mixture and fill with the main solvent up to the calibration mark (add the appropriate amount to the desired volume). Filter the mixture through a sterile filter. After heating, transfer to an injection vial and seal with a rubber stopper and crimp cap.
[0179] The list of surfactants / dispersants used is as follows:
[0180] [Table 1]
[0181] The administration and evaluation of the formulations used in Examples 1-4 are as follows.
[0182] A 1 ml / kg aliquot of the formulation was subcutaneously injected into female Wistar rats. Blood samples were then collected. The plasma was collected at various time intervals, and the plasma sample was analyzed to determine the concentration of toltrazuril in the plasma. We analyze these data. From these data, the AUC and Cmax values are known targets for clinicians. It is measured according to a standard method.
[0183] (Example 1) Table 1-B shows the volume of toltrazuril formulations in the solvent dimethyl sulfoxide (DMSO). Prepare according to the composition of the formulation, expressed in mass % (%M / V) per unit. DMSO content This represents the amount added until the value reaches 100. Table 2 shows the pharmacokinetic AUC and Cmax. The data shows the percentage change compared to a reference formulation that does not contain surfactants ("ref"). (Note: "hr" = hours).
[0184] [Table 2]
[0185] [Table 3]
[0186] The data above clearly demonstrates the positive effects of adding surfactants with an HLB of 10 or higher. However, it is not an amphiphilic compound and therefore does not have an inherently calculable HLB value. The effects of the powdered drug Kollidone™17PF have been significantly reduced.
[0187] (Example 2) In glycerol formal solvent (4-hydroxymethyl-1,3-dioxolane) The lutrazuril formulation is used in the formulation composition shown in Table 3 as mass % per volume (%M / V). Prepare accordingly. The glycerol formal content refers to the amount added until it reaches 100. Table 4 shows the pharmacokinetic AUC and Cmax data, and the reference product without surfactants. This shows the percentage change compared to the agent "ref (reference)" (Note: "hr" = time).
[0188] [Table 4]
[0189] [Table 5]
[0190] The data above clearly shows the positive effects of adding surfactants with an HLB of 10 or more. This is happening. This is not so noticeable in glycerol formal solvent, however. That is also important.
[0191] (Example 3 (Comparative Example)) Glycerol formal solvent (4-hydroxymethyl-1,3-dioxolane) and The toltrazuril preparation in 10% ethanol is expressed in the mass % (%M / V) per volume shown in Table 5. Prepare according to the composition of the formulation shown. Glycerol formal and 10% ethanol The content of ru is the amount added until it reaches 100. Table 6 shows AUC and Cmax. Pharmacokinetic data and percentages compared to a surfactant-free reference formulation "ref (reference)" To indicate change. (Note: "hr" = time)
[0192] [Table 6]
[0193] [Table 7]
[0194] The above data shows that when Lipoid S100, a surfactant with an HLB of less than 10, is added... This indicates that it has an adverse effect on pharmacokinetic parameters.
[0195] (Example 4) Preparations of 2-pyrrolidone and toltrazuril in 20% ethanol solvent, in the volumes shown in Table 7. Prepare according to the composition of the formulation expressed as mass % (%M / V) per unit. 2-Pyrrolidone The 20% ethanol content refers to the amount added until it reaches 100. Table 8 shows the drug AUC and Cmax data of the pharmacokinetics, and a reference formulation that does not contain surfactants "ref(reference) This shows the percentage change compared to ) [Note: "hr" = hours].
[0196] [Table 8]
[0197] [Table 9]
[0198] The above data shows that in 2-pyrrolidone and 20% ethanol as solvents, HLB This clearly demonstrates the positive effects of adding 10 or more surfactants.
[0199] (Examples) Examples 1-4 demonstrate the individual positive effects of adding surfactants with an HLB of 10 or higher. This is done to demonstrate the combined effect of the surfactant by adding a polynuclear iron(III) polysaccharide complex. The formulations outlined in Table 9 are described in European Patent Application Publication No. 2164496 (EP2164 It was prepared in the same manner as disclosed in 496A1).
[0200] [Table 10]
[0201] A total of 21 piglets were born from two sows, and they were divided into groups of 10 and 11 piglets respectively. They were randomly assigned to two research groups. Using both formulations, each group A single oral bolus was administered to 3-day-old piglets of Loop.
[0202] After treatment, a total of 8 samples, including the pre-treatment samples, will be taken according to a predetermined schedule. Frequent blood sampling (n=22 samples per piglet) was performed over a four-day period.
[0203] The concentration of the active substance toltrazuril in plasma was determined by turbulent chromatography / tandem mass spectrometry. It was analyzed by [method / analysis method]. The limit of quantification was 10 μg / L.
[0204] The PK data in Table 10 was calculated from the collected samples.
[0205] [Table 11]
[0206] The above data shows that the surfactants with an HLB of 10 or higher, along with polynuclear iron(III) polysaccharide complexes, are suitable for use with polynuclear iron(III) polysaccharide complexes. This clearly demonstrates the beneficial combined effect achieved by adding the compound.
[0207] Examples 1 to 4 showed the positive effect of surfactants with an HLB of 10 or higher, but Table 1 The data generated for 0 indicates further improvement in the relevant pharmacokinetic parameters. They are doing it.
[0208] (Example 6) Examples 1 to 4 show the individual positive effects of adding surfactants with an HLB of more than 10. Example 5 describes the above-mentioned interface activity by adding a polynuclear iron(III) polysaccharide complex in oral application. The aphrodisiac showed a good combined effect.
[0209] To demonstrate that the overall combined effect is not affected by a specific route of administration, see Table 11. The formulation outlined was prepared for administration by injection. (See item "ref1 (reference 1)") This is the same as the "ref (reference)" item outlined in Example 5 above, and is toltrazuril. This refers to an oral formulation containing only [the specified ingredient]. Item "ref2 (reference 2)" refers to the test item for this example. This is the same as in 1, but without the addition of activated iron.
[0210] The formulation was produced in the same manner as in Example 5.
[0211] [Table 12]
[0212] In a parallel project, three test groups were prepared, each consisting of six piglets. The animals were treated for each item on the third day after birth. The preparations related to ref1 (reference 1) The piglets in the administered group received a single oral bolus (similar to the above in Example 5). The piglets in the other two groups received a single injection of the two formulations on the third day after birth.
[0213] Frequent blood draws should be performed at 0, 4, 8, 24, 32, 48, and 72 hours. The tests were performed after each procedure on the 7th, 14th, 21st, and 28th (n=11 / animal). Plasma The concentration of the active substance toltrazuril was determined by turbulent chromatography / tandem mass spectrometry. The analysis was performed. The limit of quantification was 25 μg / L for each analyte.
[0214] The PK data shown in Table 12 was calculated from the collected samples.
[0215] [Table 13]
[0216] The above data shows that surfactants with an HLB of 10 or higher and polynuclear iron (regardless of the route of administration) III) The addition of polysaccharide complex compounds clearly demonstrates a good combined effect, but the interface activity of Example 5 Surfactants with even higher HLB compared to pharmacokinetic agents have a positive impact on achieving pharmacokinetic properties. To further enhance it.
[0217] To summarize the above examples 1 to 6, surfactants with an HLB value of 10 or more are found to be Toltraz The already improved pharmacokinetic properties of the combination of lyl polynuclear iron(III) polysaccharide complex compounds are substantial To increase, and such effects are not limited to formulations which are solutions or dispersions of the active substance. And it may become clear that such effects are not due to that particular application route.
