Abstract

The invention belongs to the technical field of medicines, and concretely relates to a medicinal composition containing prasugrel hydrochloride. The medicinal composition contains prasugrel hydrochloride, lecithin, a disintegrating agent and a lubricant, and also contains adipic acid and anhydrous ethanol. The medicinal composition has the advantages of good stability, completeness in dissolve-out, excellent quality, simplicity and easiness in production operation, and suitableness for industrial production.

Description

technical field [0001] The invention belongs to the technical field of medicines, and in particular relates to a pharmaceutical composition containing prasugrel hydrochloride and a preparation method of tablets thereof. Background technique [0002] Prasugrel hydrochloride is a new orally effective thienopyridine drug. Like clopidogrel, prasugrel hydrochloride is also an inactive prodrug, which needs to be converted into active metabolites by cytochrome P450 enzyme system. Irreversibly inhibits P2Y12 adenosine diphosphate receptors on platelets. The curative effect of prasugrel hydrochloride is better than that of clopidogrel, which can be explained from the improvement of its pharmacokinetic properties. Prasugrel hydrochloride has a higher conversion rate of prodrugs to active metabolites and higher bioavailability, so The onset of effect is faster and can reduce the difference in efficacy among individuals, and reduce the incidence of major ischemic cardiovascular events ...
