[0014] CN102048701B (Chinese Patent Application No. 201010581413.5) discloses a pitavastatin calcium enteric-coated sustained-release pellet preparation and a preparation method thereof, which can solve the following problems in the prior art: (1) pitavastatin calcium is low in gastric juice In the pH environment, configuration transformation is easy to occur, and the stability is poor; (2) the release of ordinary tablets is too fast, so that the active ingredients cannot fully exert their cholesterol-lowering effect
The above-mentioned rivaro tablets have not changed their prescriptions since they were launched in 2003

Abstract

The invention relates to a pitavastatin calcium tablet pharmaceutical composition and a dry or wet preparation method thereof. Specifically, one aspect of the invention relates to a pitavastatin calcium tablet which comprises a tablet core and a coating layer, wherein the tablet core comprises 1 part of pitavastatin calcium, 40-120 parts of a filling agent, 4-20 parts of a disintegrating agent, 0.5-5 parts of an adhesive, 0.5-5 parts of a stabilizer and 0.3-3 parts of a lubricating agent. The tablet core can be made from lactose, microcrystalline cellulose, tricalcium phosphate, low substituted hydroxypropy cellulose, crospovidone, sodium carboxymethyl starch, aluminum-magnesium silicate, aluminum-magnesium metasilicate, hydroxypropyl methylcellulose, magnesium stearate and other excipients and combinations thereof. The tablet core can be prepared through a dry granulation tabletting process or a wet granulation tabletting process. The invention further relates to a preparation method of pitavastatin calcium tablets and application thereof in preparation of drugs for treating and / or preventing hypercholesteremia or familial hypercholesterolemia. The tablet pharmaceutical composition disclosed by the invention has excellent properties shown in the specification.
