Abstract

A micropill of danshinolic acid A for relaxating the smooth muscle of aorta, improving the left ventricular function and the cardiac pump function, and preventing and treating myocardial ischemia is prepared from danshinolic acid A or its pharmacologically acceptable salt and one or more medicinal auxiliaries. A capsule containing said micropills is also disclosed.

Description

technical field [0001] The invention relates to salvianolic acid A pellets and salvianolic acid A capsules, in particular to pellets and capsules containing high-purity salvianolic acid A, and belongs to the technical field of medicine. Background technique [0002] Salvia miltiorrhiza is one of the drugs commonly used in traditional medicine in my country, and has a long history of clinical application. The chemical composition of Danshen is mainly divided into two parts: water-soluble components and fat-soluble components. In the early 20th century, fat-soluble components were mainly studied; since the 1980s, Chinese pharmaceutical researchers began to study water-soluble components, and dozens of water-soluble components were discovered in succession, and their chemical structures were clarified, which proved that the main water-soluble active components of Danshen Phenolic acid compounds. [0003] Salvianolic acid A is a phenolic acid component isolated from Salvia mil...
