Abstract

The invention relates to a trimetazidine hydrochloride sustained-release tablet. The trimetazidine hydrochloride sustained-release tablet is specifically prepared from trimetazidine hydrochloride, a framework material, a thinner and an adhesive, wherein the framework material is a mixture of hydroxypropyl methyl cellulose and zein. The trimetazidine hydrochloride sustained-release tablet has the advantages that by using the hydroxypropyl methyl cellulose and the zein as the framework material, the burst release effect in the early period of trimetazidine hydrochloride is overcime; the in-vitrorelease of the obtained sustained-release tablet is free from the influence by the pH (potential of hydrogen) environment; the release degree in 8 hours is greater than 80%; the release curve is uniform with the release curve of a market product; the trimetazidine hydrochloride sustained-release tablet is suitable for industrialized large-scale production.

Description

technical field [0001] The invention relates to a sustained-release preparation for treating angina pectoris, in particular trimetazidine hydrochloride sustained-release tablet, and a preparation method of the sustained-release tablet. Background technique [0002] Angina pectoris is a common cardiovascular disease, which is caused by coronary artery atherosclerosis and stenosis, coronary artery insufficiency, temporary myocardial ischemia and hypoxia, and a group of comprehensive symptoms with precordial pain as the main clinical manifestation. It is a kind of coronary heart disease with the highest incidence rate, which seriously threatens the health and life of human beings. It is mainly divided into stable angina and unstable angina. Angina pectoris can occur at any time in 24 hours, but most of them are from early morning to morning, and variant angina pectoris often occurs regularly at night. Therefore, it is required that the therapeutic drug can maintain an effecti...
