Sarpogrelate hydrochloride

Описание

Sarpogrelate hydrochloride, a potent and selective serotonin 5-HT₂ receptor antagonist, was launched in Japan as an antithrombotic. It exhibits inhibition of ex vivo platelet aggregation stimulated by serotonin in combination with collagen and suppression of blood vessel constriction mediated by 5-HT₂ in vitro. Its antithrombotic effects have been demonstrated in several in vivo experimental models including reduction of the mortality rate in acute pulmonary thromboembolic disease, arterial thrombosis, and peripheral obstructive disease. Sarpogrelate has been shown to be especially useful as an antiplatelet agent for patients with Type 2 diabetes mellitus, in whom 5-HT₂mediated amplification of collageninduced platelet aggregation is significantly increased.
