Embodiment 1

[0053] Make a mixture with 51mg gentamicin sulfate (700U / mg, Fluka), 51mg sodium lauryl sulfate, 280mg carnauba wax, 1118mg calcium sulfate dihydrate (Fluka) and 1ml water, mix with calcium chloride Homogenize and dry, then grind the mixture obtained. 200 mg of the mixture were each pressed into oblate molded bodies with a diameter of 13 mm within two minutes using a press with a pressure of 5 tons.

Embodiment 2

[0055] Make a mixture with 51mg gentamicin sulfate (700U / mg, Fluka), 51mg sodium lauryl sulfate, 140mg beeswax, 1258mg calcium sulfate dihydrate (Fluka) and 1ml water, mix well with calcium chloride Let dry and grind the mixture obtained. Each 200 mg of the mixture was pressed into oblate molded bodies with a diameter of 13 mm within two minutes using a press with a pressure of 5 tons.

Embodiment 3

[0057] The molded bodies obtained in Examples 1 and 2 were immersed in physiological saline and left at 37°C for 12 days to measure the delayed release of the antibiotic component. After standing for 1, 3, 6, 9 and 12 days, samples were taken for inspection. Through the agar diffusion test, Bacillus subtilis ATCC 6633 was used as the standard microorganism to determine the value of antibiotics (results are shown in Table 1).

Abstract

The invention relates to a preparation method and application of an antibiotic preparation used in human medicine and veterinary medicine for treating local microbial infection of hard tissue and soft tissue. The preparation method of the antibiotic preparation of the present invention is as follows: by water and a kind of amphoteric component such as alkyl sulfate etc., and one or more are selected from aminoglycoside antibiotics, lincosamides (Lincosamid) antibiotics, tetracycline antibiotics Components, an organic auxiliary component and/or an inorganic auxiliary component, and if necessary at least one biologically active auxiliary component are mixed with each other and can be further prepared into molded bodies, granules, powders , film, felt and thread.

Description

technical field [0001] The present invention relates to the preparation and application of an antimicrobial preparation capable of delaying the release of active substances used in human medicine and veterinary medicine for treating local microbial infections of hard and soft tissues. Background technique [0002] In human and veterinary medicine, the treatment of local soft and hard tissue microbial infections requires high concentrations of topical antibiotics in the area of ​​infected tissue. It has long been known that the continuous use of antibiotics has its own set of problems. When continuous medication is used, it is often necessary to use a very high dose of antibiotics in order to achieve an effective antibacterial concentration of antibiotics in the infected tissue. Thus, especially in the case of aminoglycoside antibiotics and tetracycline antibiotics, their kidney and ear toxicity can seriously damage the body. Therefore, it is easy for people to think of loc...
