Abstract

The invention relates to a gentamycin sulfate capsule which is prepared by the following raw materials in percent by weight: 20-40 percent of gentamycin sulfate, 20-65 percent of starch, 5-25 percent of calcium sulfate, 0.5-10 percent of microcrystalline cellulose, 0.5-5 percent of hydroxy propyl methyl cellulose and 5-20 percent of lubricating agent. The capsule adds the stability of gentamycin sulfate, also avoids the bitterness of gentamycin sulfate, and increases the compliance of patients.

Description

technical field [0001] The invention relates to a capsule preparation of medicines, in particular to a gentamicin sulfate capsule and a preparation method thereof. Background technique [0002] Gentamicin sulfate is an aminoglycoside broad-spectrum antibiotic produced by Micromonospora. It is a multi-component antibiotic, and its sulfate is commonly used. [0003] Gentamicin hinders the initiation of protein synthesis by inhibiting the formation of the 70S synthesis initiation complex and causing the dissociation of N-methionyl-tRNA from the 70S synthesis initiation complex, so it has antibacterial and bactericidal effects on All kinds of Gram-negative bacteria and Gram-positive bacteria have good antibacterial effect, and have good antibacterial effect on various Enterobacteriaceae bacteria such as Escherichia coli, Klebsiella, Proteus, Salmonella, Shigella, Enterobacteriaceae Bacillus, Serratia and Pseudomonas aeruginosa have good antibacterial effect. Neisseria and Haem...
