Problems solved by technology

[0008] Starch is formed by the polymerization of glucose molecules. It is the basic auxiliary material of oral solid preparations. It is often used as a binder, diluent and disintegrating agent in chewable tablets. The starch is extracted from natural substances such as corn and cassava. It is safe, reliable, It is cheap and easy to obtain, but there is no report on the use of starch alone as an auxiliary material for the production of chewable tablets

Abstract

The invention provides an erythromycin ethylsuccinate chewable tablet and a preparation method thereof, and relates to the technical field of medicine production. The erythromycin ethylsuccinate chewable tablet consists of erythromycin ethylsuccinate, starch and sucrose. The tablet disclosed by the invention is capable of overcoming the shortcomings of a normal chewable tablet, and reducing the variety and dosage of accessories in the erythromycin ethylsuccinate chewable tablet; and the medicine preparation is excellent in performance, high in bioavailability, good in stability, high in patient acceptability and free from grittiness, and has important clinical application value.

Description

technical field [0001] The invention relates to the technical field of medicine and medicine production, in particular to a chewable tablet of erythromycin ethylsuccinate and a preparation method thereof. Background technique [0002] Tablets are stable in quality and easy to take, and are the most basic and commonly used preparation form. However, for children, the elderly, and patients with dysphagia, ordinary tablets are often difficult to take, and long-term medication may even lead to psychological drug resistance. Chewable tablets can make up for this deficiency. Chewable tablets are a type of tablet that can be chewed and swallowed in the oral cavity. They are generally the same size as ordinary tablets, and can be made into special-shaped tablets of different shapes according to needs. The tablet is easy to swallow after being chewed, and the surface area of ​​the tablet increases, which can promote the dissolution and absorption of the drug in the body. For drugs ...
