Abstract

The invention discloses a salidroside enteric-coated tablet and a preparation method thereof. The tablet comprises a salidroside tablet core and an enteric-coated layer. The salidroside tablet core is composed of salidroside main drug and auxiliary materials. The auxiliary materials include: diluents, disintegrating agents, binders, lubricants, intestinal absorption promoting agents and pH regulators, etc. Enteric coatings include: hydroxypropylmethylcellulose phthalate or cellulose acetate phthalate, etc. The invention solves the problem of salidroside being unstable in gastric juice and at the same time solves the problem of insufficient absorption of salidroside in intestinal tract.

Description

Technical field [0001] The invention relates to a salidroside enteric-coated tablet and a preparation method thereof. Background technique [0002] Rhodiola is a precious medicinal material of Chinese medicine and Tibetan medicine. Salidroside is the active ingredient in Rhodiola. At present, salidroside can be obtained by chemical synthesis or extraction from plants. Pharmacological studies have shown that salidroside has good cardiovascular and cerebrovascular effects, such as improving vascular effects, protecting myocardial ischemia, improving heart function, and anti-arrhythmia. [0003] In addition, patent research shows that salidroside has new effects in preventing and treating muscle atrophy, stroke, anti-asthma, anti-depression and so on. Patent CN102727505A discloses that salidroside can inhibit the expression of muscle atrophy-specific factor Atrogin-1, myotube atrophy and the reduction of the cross-sectional area of ​​skeletal muscle fibers in the process of muscle ...
