Description

technical field [0001] The invention belongs to the technical field of medicines, and in particular relates to an oral solid composition of sargrel hydrochloride and its preparation process and application. Background technique [0002] Sarpogrelate hydrochloride is a 5-hydroxytryptamine (5-HT2) receptor blocker that can specifically bind to 5-HT2 receptors. 5-hydroxytryptamine (5-HT) was first proposed as a vasoactive substance in 1955. 5-HT exists widely in animals, especially in the cardiovascular system. Except for a small part that is re-uptaked and stored in platelets, almost all 5-HT is inactivated by endothelial cells in the liver and lungs. Sagrelate hydrochloride can specifically bind to 5-HT2 receptors, showing a special antagonistic effect on receptors on platelets and vascular smooth muscle. Therefore, it exhibits anti-platelet effect and inhibits vasoconstriction, and exerts a series of biological effects. Sagrelate hydrochloride is an antithrombotic drug, m...
