Abstract

The invention discloses a method for preparing compound simvastatin nicotinate sustained-release capsules, and belongs to the field of medicinal preparations. Components of the simvastatin nicotinate sustained-release capsules can exert a synergistic effect in vitro and comprehensively regulate the components of blood fat, so that the medicinal effect is furthest exerted, the toxic or side effect of the medicament can be reduced, fluctuation of blood concentration in vitro is reduced, and the administration frequency of a patient is reduced; and by designing pellets, the contact area between the medicament and the digestive tract is greatly improved, and the bioavailability of the medicament is improved. The method is strong in specificity, good in reproducibility, high in precision and convenient to operate; the capsules can be well applied to treatment of hyperlipidemia and abnormal mixed blood fat; and safety, effectiveness and controllability of clinical medication are really ensured.

Description

technical field [0001] The invention relates to a preparation method of compound simvastatin nicotinic acid sustained-release capsules, belonging to the field of pharmaceutical preparations. Background technique [0002] Cardiovascular disease is currently a killer that threatens human health, and its morbidity and mortality have surpassed tumors and ranked first. A survey on the causes of death in our country showed that cardiovascular diseases accounted for 40%. The most important cause of cardiovascular disease is atherosclerosis, which is the most common and important type of vascular sclerosis. Lesions mainly occurred in the aortic coronary arteries and cerebral arteries, renal arteries and mesenteric arteries also occurred. The pathological changes involve the arterial intima, subintimal layer and middle layer. Lipids accumulate at the lesion site and invade the intracellular or subintimal intercellular spaces, resulting in smooth muscle cell and connective tissue h...
