Problems solved by technology

[0007] 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 loratadine composition chewable tablets and a preparation method thereof, and relates to the technical field of medicine and medicine production. The loratadine composition chewable tablets comprise loratadine, starch and sucrose; the tablets overcome the shortcomings of common chewable tablets, and the types and amount of accessories in the loratadine chewable tablets are reduced; and the medicine preparation has good performance, high bioavailability and good stability, is highly accepted by patients, avoids gritty feel and has an important value in clinical application.

Description

technical field [0001] The invention relates to the technical field of medicine and medicine production, in particular to a loratadine composition chewable tablet 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 that are...
