Abstract

The invention discloses salidroside enteric-coated tablets and a preparation method thereof. The tablets comprise salidroside tablet cores and an enteric layer, wherein the salidroside tablet cores are composed of a salidroside main medicine and auxiliary materials, and the auxiliary materials comprise a diluent, a disintegrant, an adhesive, a lubricant, an intestinal absorption accelerant, a pH regulator and the like; an enteric coating comprises hydroxypropyl methylcellulose phthalate or cellulose acetate phthalate and the like. According to the salidroside enteric-coated tablets and the preparation method thereof disclosed by the invention, the problem of instability of salidroside in gastric juice is solved, and the problem of inadequate absorption of salidroside in intestinal tracts is solved simultaneously.

Description

technical field [0001] The invention relates to a salidroside enteric-coated tablet and a preparation method thereof. Background technique [0002] Rhodiola rosea is a precious medicinal material of traditional Chinese medicine and Tibetan medicine. Salidroside is the active ingredient in Rhodiola rosea. 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, myocardial ischemia protection, improving heart function, anti-arrhythmia and other pharmacological functions. [0003] In addition, patent research shows that salidroside has new effects such as preventing and treating muscle atrophy, stroke, anti-asthma, and anti-depression. Patent CN102727505A discloses that salidroside can inhibit the expression of muscle atrophy-specific factor Atrogin-1, myotube atrophy and the reduction of skeletal muscl...
