Abstract

The invention discloses a tablet composition containing pitavastatin calcium and a preparation method of the tablet composition. The tablet composition contains main medicine-pitavastatin calcium, porous filler, a disintegrating agent, a lubricating agent and opadry film premix. A direct powder compression method is adopted; the stability of a product is remarkably improved.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, in particular to a tablet composition containing pitavastatin calcium and a preparation method thereof. technical background [0002] Pitavastatin Calcium is a new generation of hydroxymethylglutaryl-CoA reductase inhibitor, which can lower blood lipid and resist arteriosclerosis by inhibiting the synthesis of endogenous cholesterol. Clinically, it is mainly used to treat hypercholesterolemia, familial hypercholesterolemia and lipid metabolism disorders. A large number of clinical experiment data show that pitavastatin calcium generally has good drug resistance, low toxicity and side effects, and obvious therapeutic effect, which makes it have the reputation of "super statin" among statin drugs. [0003] The traditional pitavastatin calcium tablet composition and its preparation method are wet granulated and then pressed into tablets. The raw and auxiliary materials are affected by dam...
