Description

Technical Field

[0001] The present invention relates to a combination of crude drugs for preventing or treating epileptic seizures and its uses, and also relates to a pharmaceutical combination comprising a combination of crude drugs and at least one antiepileptic drug and its uses.

Background Art

[0002] The description of the background art contains information helpful for understanding the present invention, and all information provided in this specification should not be regarded as the background art or the technology related to the present invention. Also, any publications cited explicitly or implicitly should not be regarded as the background art.

[0003] Epilepsy is a common neurological disorder that plagues approximately 70 million people worldwide. The characteristics of this disease are recurrent, spontaneous, and unpredictable seizures caused by abnormal discharges of brain nerve cells, mainly occurring in the cerebral cortex and hippocampus. The causes of epilepsy are related to congenital or acquired brain lesions, such as brain damage, infection, stroke, brain tumor, etc., but the seizures of 70% of patients are of unknown origin. Although the cause of most epilepsy is unknown, it is generally considered that the balance between the brain inhibitory nervous system (i.e., GABA system) and the excitatory nervous system (i.e., glutamate system) is disrupted, causing excessive excitation of brain nerve cells.

[0004] Currently, the mechanisms of action of anti-epileptic drugs that suppress epileptic seizures mainly include drugs that directly suppress the excitability of brain nerve cells by blocking sodium channels (e.g., phenytoin, carbamazepine), drugs that suppress glutamate (e.g., lamotrigine, felbamate), or drugs that increase GABA (e.g., benzodiazepines, tiagabine, vigabatrin), etc., to regulate the stability of brain nerve cells. However, there are currently nearly 30 types of anti-epileptic drugs, but about one-third of epilepsy patients have drug resistance to the therapeutic drugs, and the side effects of the drugs also affect the patient's adherence to the current therapeutic drugs used.

[0005] Currently, it is known that commonly used anti-epileptic drugs have many side effects. For example, in the package insert of carbamazepine, side effects such as drowsiness, loss of appetite, diarrhea, dizziness, heaviness in the head, ataxia (coordination movement disorder), leukopenia, aplastic anemia, liver dysfunction, arrhythmia, and rash are described. In the package insert of phenytoin, side effects such as nausea, vomiting, heartburn, loss of appetite, diplopia, nystagmus, ataxia (coordination movement disorder), gingival hyperplasia, hirsutism, facial roughness, involuntary movement, lymph node swelling, malformation, and rash are described. The usual treatment methods after side effects occur are to change the drug, reduce the dosage, or add other drugs to suppress the side effects. However, reducing the dosage makes epilepsy likely to recur, which is painful for the patient both physically and mentally.

[0006] Therefore, it is necessary to search for and develop new drugs that are more effective and safe in the treatment of epilepsy. Medicinal plants have attracted attention because they are widely used in traditional and folk medicine for the treatment and prevention of different nervous system diseases (including epilepsy). In recent years, many plant-derived bioactive molecules have been proven to have an anti-epileptic effect by affecting ion channels, GABA, or glutamate. For example, flavonoids, alkaloids, terpenoids, cannabidiol, etc., medicinal plants have become the research targets of anti-epileptic drugs.

[0007] Taiwan Qingguan No. 1 (NRICM101) is a herbal medicine developed by the National Research Institute of Chinese Medicine in 2020 based on the prescription of "Jingfang Baidu Powder" in the "Shengbai Zhongmiaofang" of the Ming Dynasty and is used for the treatment of the novel coronavirus (COVID-19). It has antiviral, immune regulation and anti-inflammatory effects. Taiwan Qingguan No. 1 is prepared by mixing 10 herbal medicines including Scutellaria Root (Scutellaria baicalensis), Heartleaf Houttuymia (Houttuynia cordata), Indigowoad Root (Isatis indigotica), Mongolian Snakegourd Fruit (Trichosanthes kirilowii), Mulberry Leaf (Morus alba), Magnolia Bark (Magnolia officinalis), Peppermint Herb (Mentha haplocalyx), Fineleaf Nepeta (Nepeta tenuifolia), Saposhnikovia Root (Saposhnikovia divaricate) and Baked Liquorice Root (Glycyrrhiza glabra). Furthermore, various bioactive components have also been discovered in Taiwan Qingguan No. 1. For example, baicalein, epigoitrin, liquiritin, quercetin-3-galactoside, quercetin-3-isorhamnetin, scutellarin, rutin, oroxindin, chlorogenic acid, etc. These components may be the cause of the pharmacological properties of Taiwan Qingguan No. 1. However, there is still no data exploring the anti-epileptic effect of Taiwan Qingguan No. 1. Such an anti-epileptic effect may provide a new option for preventing or treating epileptic seizures, or may reduce the side effects of conventional anti-epileptic drugs by combining with other anti-epileptic drugs.

[0039] The crude drugs contained in the crude drug composition of the present invention are manufactured into liquid preparations through processes such as washing, drying, grinding, and processing. In one embodiment, the liquid preparation is further manufactured into a solid preparation through processes such as extraction, concentration, addition of excipients, and spray granulation. The above manufacturing processes can be increased or decreased according to the dosage forms manufactured by conventional crude drug pharmaceutical technologies.

[0040] In one aspect, the crude drug composition of the present invention can be used in a combination of one or more kinds of pharmaceuticals for preventing or treating epilepsy, or manufactured into a combination of pharmaceuticals. These drugs include known compounds (such as purchasable compounds) for treating, preventing, or alleviating epilepsy symptoms.

[0041] In one embodiment, the present invention provides a method for treating or preventing epilepsy in a subject. This method includes administering the herbal medicine composition of the present invention to the subject in a therapeutically effective amount. In another embodiment, the subject is further co-administered with at least one drug effective for treating or preventing epilepsy. In another embodiment, at least one drug includes, for example, phenytoin, carbamazepine, lamotrigine, felbamate, benzodiazepine, tiagabine, vigabatrin, etc. The dosage of Western medicine can be formulated by a doctor according to the recommended dosage of each drug.

[0042] In one embodiment, the subject with epilepsy is a person who has been newly diagnosed with epilepsy or a person who is taking at least one anti-epileptic drug. In one embodiment, when a combination of the herbal medicine composition of the present invention and at least one anti-epileptic drug is given to a subject newly diagnosed with epilepsy and at least one anti-epileptic drug is administered in combination for prevention or treatment, the dosage is less than the dosage when the anti-epileptic drug is administered alone. In another embodiment, the herbal medicine composition of the present invention is given to a subject who is taking at least one anti-epileptic drug, and further the dosage of the anti-epileptic drug can be reduced.

[0043] The treatment method affects an effective amount of the combination. The therapeutic formulation can be administered to the patient before or after the onset of the disease or symptom. Further, it can be administered daily, or in divided doses at several times and in alternating shifted doses in sequence, or the doses can be administered continuously. In addition, according to the urgency of the treatment or prevention situation, the dosage of the proportional therapeutic formulation can be increased or decreased.

[0044] By administering the herbal medicine composition of the present invention to a patient in an already known order, dosage, and period, epilepsy can be effectively treated or prevented. The effective amount of the herbal medicine composition required for the effect of treating and / or preventing epilepsy varies depending on many factors, such as the activity of the specific herbal medicine composition used; the administration time; the excretion rate of the extract; the duration of treatment; other drugs, compounds, or substances used in combination with the extract; the state of the disease or medical condition before the patient receives treatment, the patient's age, gender, weight, symptoms, general health status, and previous medical history; similar factors well-known in the medical field, etc. The dosage, etc. is adjusted to provide an excellent therapeutic response. For example, a dosage divided into several times a day is administered, or the dosage is decreased in proportion to the urgency of the treatment situation.

[0045] The description of the herbal medicine composition of the present invention is mainly for administration to humans in a method suitable for medical ethics. For those skilled in the art, it should be understandable that the herbal medicine composition is usually suitable for various animals. In order to be able to administer to various animals, it is well-known that the recombination of the herbal medicine composition of the present invention can be carried out, and veterinary pharmacists familiar with the technology can design and implement such recombination by general experiments (if necessary). The subjects to which the herbal medicine composition of the present invention can be administered include humans and other primates, non-mammals, commercially valuable mammals, such as cows, pigs, horses, sheep, cats, and dogs, etc., without limitation.

[0046] In some embodiments, the herbal medicine composition of the present invention is administered to a patient at a dosage of 1 to 5 times a day or even more. In other embodiments, the herbal medicine composition of the present invention is administered to a patient at a dosage of once a day, twice a day, three times a day, four times a day, once every two days, once every three days to one week, or once every two weeks. It is easy for those skilled in the art to understand that the administration frequency of each combination composition of the present invention varies depending on the tester, and the administration frequency is affected by many factors, including age, the disease or medical condition to be treated, gender, overall health status, and other factors, without limitation. Therefore, the present invention should not be construed as being limited to any specific dosage plan, and the attending physician should consider all factors related to the patient and confirm the exact dosage and composition to be administered to the patient.

[0047] In one embodiment, when the crude drug composition of the present invention is administered in combination with at least one anti-epileptic drug, the crude drug composition and at least one anti-epileptic drug can be simultaneously administered to the subject. In another embodiment, the crude drug composition and at least one anti-epileptic drug can be administered to the subject in sequence, before and after, or with an interval therebetween.

[0048] Administration method: Oral administration; The dosage form of the crude drug composition of the present invention for oral administration is solid or liquid. Suitable solid dosage forms include, for example, powders, fine granules, granules, pills, tablets, capsules, lozenges, etc. Suitable liquid preparations include solutions, syrup preparations, suspensions, dispersions, concentrated solutions, etc. These dosage forms are manufactured by selecting and adding pharmaceutically acceptable additives according to conventional pharmaceutical methods.

[0049] Those skilled in the art should be able to understand that by conducting experiments within the normal range, equivalent items such as the specific order, implementation method, scope of claims, and examples described in the present invention can be confirmed. These equivalent items are recognized within the scope of the present invention and are further included in the scope of the claims. For example, modifications of reaction conditions such as reaction time, reaction state / volume, and experimental reagents (such as solvents, catalysts), pressure, atmospheric pressure conditions, and reducing / oxidizing agents, as well as alternatives recognized in the technical field and experiments within the normal range, are all within the scope of the present invention.

[0050] Regarding all numerical values and ranges mentioned in this specification, the description of the range is for convenience and brevity and should not be construed as a limitation on the scope of the present invention. Therefore, all numerical values and ranges included in the numerical values and ranges are included within the scope of the present invention. Also, the upper or lower limits of all numerical values and numerical ranges falling within these ranges are also within the contemplation of the present invention. The description of the range specifically discloses all possible sub-ranges and individual numerical values within the range, and in appropriate cases, some integers of the numerical values are also included within the range. For example, the description of the range from 1 to 6 is considered to specifically disclose sub-ranges, such as from 1 to 3, from 1 to 4, from 1 to 5, from 2 to 4, from 2 to 6, from 3 to 6, etc., and individual numbers within the range, such as 1, 2, 2.7, 3, 4, 5, 5.3, and 6, etc., are all applicable regardless of the range.

[0051] The following examples further illustrate various aspects of the present invention. However, they are not a limitation on the teachings or disclosure of the present invention described herein.

[0052] The present invention will be described with reference to the following examples. These examples are for illustrative purposes only, and the present invention is not limited by these examples. All variations that include the teachings provided herein will be apparent.

[0053] The crude drug compositions exemplified in the present invention are manufactured and / or tested by the following steps.

[0054] The crude drug composition used in one example uses commercially available drugs (Shuntenro, Taiwan Qingguan No. 1).

[0055] Male Sprague-Dawley rats (SD, 150 - 200 g) are purchased from BioLASCO TAIWAN Co., Ltd and housed in the Experimental Animal Center of Fu Jen Catholic University. All animal experiments have obtained permission from the Experimental Animal Management Committee of Fu Jen Catholic University. In accordance with the 3R rules, all experiments are conducted with the minimum number of animals and with the least possible animal suffering while producing reliable results.

[0056] [Component Analysis of Example 1 - NRICM101] Regarding the chemical characteristics of plants in Taiwan Qingguan No. 1 (NRICM101), some standard compounds were selected from the literature, and some active compounds were further identified from the methanol extract. The structures of these compounds were confirmed by 3D fingerprint analysis.

[0057] For high-performance liquid chromatography (HPLC) analysis, 20 mL of 70% methanol was sonicated at 25 °C for 20 minutes to extract 0.5 g of NRICM101. Then, the NRICM101 sample was filtered through a 0.45 μm syringe filter.

[0058] The Waters HPLC system (Milford, Massachusetts, USA) is composed of a Waters 600 pump system, a Waters 2996 photodiode array detector, a Waters 717 autosampler, and a Sugai U-620 column heater (Wakayama, Japan). The stationary phase is a combination of a Cosmosil 5C18-MS-II packed column (5 μm, 4.6 mm × 250 mm, Nacalai tesque, Japan) and a Lichrospher RP-18 high-performance liquid chromatography column (5 μm, 4.0 mm × 10 mm, Merck, Germany). Gradient elution is combined from eluents A, B, and C (A: H2O / KH2PO4 / 10% H3PO4 = 1000 mL / 2.72 g / 1 mL; B: acetonitrile; C: H2O), and gradient elution is performed as follows: from 0 to 30 minutes, 90% - 75% A and 10% - 25% B; from 30 to 40 minutes, 75% - 65% A and 25% - 35% B; from 40 to 55 minutes, 65% - 0% A, 35% - 75% B, and 0% - 25% C; from 55 to 60 minutes, 75% - 10% B and 25% - 90% C; from 60 to 65 minutes, 0% - 90% A, 10% - 10% B, and 90% - 0% C. Gradient elution is used for 3D fingerprint analysis, and the peaks of liquiritin (25.94 minutes, 280 nm), rosmarinic acid (29.44 minutes, 320 nm), baicalin (34.61 minutes, 280 nm), oroxylin A-7-O-glucuronide (40.39 minutes, 280 nm), (wogonin-7-O-glucuronide) (42.53 minutes, 280 nm), glycyrrhizic acid (51.37 minutes, 250 nm), and magnolol (61.79 minutes, 290 nm) are detected. The flow rate is maintained at 1 mL / min, and the column temperature is maintained at 35 °C.

[0059] Figure 1 shows the chromatography of NRICM101. Among the freeze-dried extracts of NRICM101, the contents of baicalin, oroxylin A-7-O-glucuronide, wogonin-7-O-glucuronide, glycyrrhizic acid, liquiritin, magnolol, and rosmarinic acid are 18.34, 1.33, 2.67, 2.42, 1.70, 1.07, and 0.91 mg / g, respectively.

[0060] [Model of animal epilepsy induced by Example 2-KA] The anti-epileptic effect of the crude drug composition of the present invention is evaluated using an animal epilepsy induction model by kainic acid (KA). KA is an analogue of glutamic acid. When KA is injected into rats, the release of glutamic acid is increased, and the glutamic acid receptor is overly activated, thereby causing progressive limbic seizures. This causes an increase in calcium ions in nerve cells, oxidative stress, and mitochondrial function defects, leading to the death of nerve cells in many regions of the brain, especially in the cerebral cortex and hippocampal area. Furthermore, KA is related to the induction of an inflammatory response consisting of nerve cell death, activation of glial cells, and inflammatory-related molecules (e.g., interleukin 1β (IL-1β), interleukin 6 (IL-6), tumor necrosis factor α (TNF-α), high-mobility group protein (HMGB1), interleukin 1 receptor 1 (IL-1R1), toll-like receptor 4 (TLR-4)). Since these pathological changes induced by KA are similar to human epileptic behavior, the model of animal epilepsy induced by KA is a new compound widely used in screening for anti-epileptic activity.

[0061] After injecting KA into the abdominal cavity of rats, the epileptic behavior within 4 hours is analyzed. The evaluation method of seizure severity is based on the Racine scale (1972) and is shown in Table 1.

[0062]

Table 1

[0063] [Evaluation of the Effect of the Herbal Medicine Composition on Animal Seizure Behavior Induced by Example 3-KA] To evaluate the effect of the herbal medicine composition on animal seizure behavior induced by KA, physiological saline, the herbal medicine composition, and CBZ were administered daily at a fixed time by pipette, and KA (15 mg / kg) was intraperitoneally injected 7 days later. The seizure behavior was analyzed within 4 hours after the intraperitoneal injection of KA into the rats, and the seizure behavior was evaluated according to the above Racine scale (1972).

[0064] Different test substances are administered to Sprague-Dawley rats and divided into the following groups. 1. Negative control group: Physiological saline. 2. KA group: The test substance is not administered before injecting kainic acid (KA). 3. Low-dose herbal medicine composition group: 100 mg / kg of the herbal medicine composition. 4. Medium-dose herbal medicine composition group: 200 mg / kg of the herbal medicine composition. 5. High-dose herbal medicine composition group: 300 mg / kg of the herbal medicine composition. 6. Antiepileptic drug group: 100 mg / kg of carbamazepine (CBZ). 7. Antiepileptic drug composition group: Contains 100 mg / kg of the herbal medicine composition and 50 mg / kg of carbamazepine (CBZ).

[0065] Rats in each group are given the test substance daily at a fixed time by pipette, physiological saline is given to the control group, the herbal medicine composition is given to the herbal medicine composition group, carbamazepine is given to the antiepileptic drug group, and the herbal medicine composition and carbamazepine are given to the antiepileptic drug composition group. The herbal medicine composition and carbamazepine are mixed with physiological saline in powder form and then given to the rats. 7 days later, except for the negative control group, rats in each group are intraperitoneally injected with KA (15 mg / kg / i.p. / once). Note that the dosage of KA injection is based on previous studies. The seizure behavior of the rats is analyzed within 3 hours after the intraperitoneal injection of KA, and the results are shown in Figure 2.

[0066] As shown in Figure 2, compared with the KA group, the high-dose group (300 mg / kg) of the crude drug composition of the present invention has a significant effect (p < 0.001). Also, the number of animals that did not have epileptic seizures after treatment with the high-dose group of the crude drug composition was the largest (77%, p < 0.001), followed by the medium-dose group (200 mg / kg) of the crude drug composition (33%, p > 0.05) or the low-dose group (100 mg / kg) of the crude drug composition (40%, p > 0.05). In addition, the high-dose group of the crude drug composition is similar (p > 0.05) to 100 mg / kg CBZ in terms of the time of epileptic seizures and the influence on epilepsy evaluation. Such results prove that the crude drug composition of the present invention has an anti-epileptic effect against KA. In other words, the crude drug composition of the present invention can be used as an alternative to anti-epileptic drugs.

[0067] Furthermore, in the anti-epileptic drug composition group (100 mg / kg of crude drug composition + 50 mg / kg of CBZ), the time and degree of animal epileptic seizures are significantly improved (p < 0.05) compared with the KA (15 mg / kg) group. In other words, the anti-epileptic drug composition can greatly improve the drawback that low-dose anti-epileptic drugs cannot effectively suppress epileptic symptoms. Since the anti-epileptic drug composition group has an anti-epileptic effect against KA similar to that of the anti-epileptic drug group, the results show that combining a low-dose (100 mg / kg) of the crude drug composition and a low-dose (50 mg / kg) of CBZ can prevent KA-induced animal epilepsy, and the low-dose CBZ can further reduce the side effects of anti-epileptic drugs.

[0068] As demonstrated in the rat experiments, the method provided by the present invention can prevent epileptic seizures and has a significant preventive and therapeutic effect on particularly intractable epilepsy symptoms. When the herbal medicine composition of the present invention is used alone, an anti-epileptic effect equivalent to that of an anti-epileptic drug (e.g., CBZ) can be obtained. In other words, the herbal medicine composition can be used instead of an anti-epileptic drug. Further, when the herbal medicine composition of the present invention and an anti-epileptic drug are used in combination, an anti-epileptic effect can be obtained and the dosage of the anti-epileptic drug (e.g., CBZ) can be reduced. Therefore, whether the herbal medicine composition of the present invention is used alone or in combination with an anti-epileptic drug, the side effects of the anti-epileptic drug can be reduced. Since the method provided by the present invention has low toxicity and side effects, it becomes one of the safe and effective epilepsy prevention methods.

[0069] [Evaluate the effect of the herbal medicine composition on animal epileptic behavior induced by Example 4-KA by electroencephalogram recording] Divide the rats into 3 groups as in the above example, and give physiological saline to the control group with a dropper at a fixed time every day, give the herbal medicine composition to the herbal medicine composition group, give carbamazepine to the anti-epileptic drug group, and give the herbal medicine composition and carbamazepine to the anti-epileptic drug composition group. After 7 days, except for the negative control group, inject KA (15 mg / kg / i.p. / once) intraperitoneally into the rats in each group. Note that the dosage of KA injection is based on previous research. Analyze the electroencephalogram within 3 hours after intraperitoneal injection of KA for epileptic seizures.

[0070] Electroencephalogram (EEG) recording is performed using a 3-channel EEG system (Pinnacle Technology Inc., Lawrence, Kansas, USA) based on the above method (see references). After anesthetizing the rats with 3% isoflurane, they are fixed in a stereotaxic frame (RWD, Life.Science, Dover, USA), and four electrodes are implanted surgically. Two of the electrodes are placed on both sides of the prefrontal cortex of bregma (anteroposterior position (AP), +3.9; medial (M) ±2.0), and the remaining two are placed in the parietal cortex (AP - 6.4, ML ±4.0). The surgery is performed under isoflurane anesthesia. One week after the surgery, the rats are connected to an EEG amplifier (mode #8213 - SE3), and further, a data acquisition system (Pinnacle Technology Inc., Lawrence, Kansas, USA) is used to record the EEG signals for 3 hours. The electrical signals from the brain are pre-amplified by an 8-channel explorer (HS-8-CNR-MDR50, Neuralynx). Then, the signals are digitized at 1.6 kHz, and further, online band-pass filtering is recorded between 0.1 and 100 Hz by Cheetah 6.2.0 recording software. In the determined recordings, the criteria for epileptic seizures are high-amplitude, rhythmic discharges, including repetitive peaks, peak-wave discharges, and slow waves, and the duration is at least 10 seconds. The PAL-8200EEG software (Pinnacl Technologies) is used to analyze the number and duration of epileptic seizures in the EEG.

[0071] The seizure peak of the rat brain is evaluated by electroencephalogram recording. As shown in FIGS. 3A and 3B, compared with the control group, treatment with KA increased the number and duration of seizure peaks. However, compared with the KA group, the number and duration of seizures in the NRICM101 300 mg / kg + KA group (high-dose crude drug composition group) and the NRICM101 100 mg / kg + CBZ 50 mg / kg + KA group (antiepileptic drug composition group) were decreased, and this effect was also similar to that of the CBZ 100 mg / kg + KA group (antiepileptic drug group) (p>0.05). From these results, both the crude drug composition of the present invention and the combination of the crude drug composition and an antiepileptic drug have the effect of preventing epilepsy induced by KA. Also, when the crude drug composition of the present invention is combined with an antiepileptic drug, it has an antiepileptic effect and can also reduce the dosage of the antiepileptic drug (such as CBZ).

[0072] Based on the results of the above animal experiments, since the crude drug composition of the present invention can extend the time for suppressing epilepsy induced by KA and can reduce the degree of epilepsy induced by KA, it can be proved that the crude drug composition has the effect of preventing epilepsy. Thereby, the crude drug composition of the present invention is used for the development of antiepileptic drugs and / or related products.
