Abstract

The invention discloses a drug for treatment of acute and chronic bacterial infection caused by sensitive bacteria and a preparation method thereof. The drug for treatment of acute and chronic bacterial infection caused by sensitive bacteria comprises the following components by weight: 100 parts of erythromycin estolate, 50-70 parts of sodium alginate, 40-50 parts of hydroxypropyl methyl cellulose, 150-190 parts of glucan, 30-50 parts of sodium carboxymethyl starch, 30-40 parts of sodium dodecyl sulfate, and 5-7 parts of aerosol. The preparation method provided by the invention employs sodium alginate inclusion technology to prepare erythromycin estolate into an inclusion compound, and then the main drug inclusion compound is further prepared into dispersible tablets. The erythromycin estolate product prepared by the method provided by the invention has increased solubility, high dissolution rate, shortened disintegration time, and improved bioavailability and curative effect. The preparation method has the characteristics of simple process, low production cost, low energy consumption, and easy realization of industrial production.

Description

technical field [0001] The invention belongs to the field of medicines and relates to a medicine and a preparation method thereof, in particular to a medicine for treating acute and chronic bacterial infections caused by sensitive bacteria and a preparation method thereof. Background technique [0002] Erythromycin Erythromycin, English name Erythromycin Estolate, Chinese alias erythromycin propionate dodecyl sulfate, erythromycin propionate dodecyl sulfate, erythromycin sulfate laurate, odorless erythromycin dry Syrup, odorless erythromycin, this product is a macrolide antibiotic, which is the dodecyl sulfate of erythromycin propionate.
