Problems solved by technology

However, the problem caused by a large amount of disintegrants is that it is easy to absorb moisture, which leads to the degradation of atorvastatin calcium
Furthermore, a certain amount of sodium lauryl sulfate is added to the formula to improve the dissolution rate in vitro, but the addition of surfactants will cause gastrointestinal irritation
[0010] Chinese patent CN102309462A provides a kind of atorvastatin calcium tablet, which adopts dry secondary granulation technology, the process is relatively complicated, the stability is poor, and it cannot be completely dissolved in acid
However, the tablet only dissolves 60% in 30 minutes in acid, and fails to dissolve rapidly completely.
At the same time, lactose is an acidic substance, which will lead to the degradation of atorvastatin calcium

Abstract

The invention relates to the technical field of pharmaceutical preparations, in particular to an atorvastatin calcium tablet and a preparation process thereof. The atorvastatin calcium tablet comprises the following components in parts by weight: 5-15 parts of atorvastatin calcium, 40-70 parts of filler, 1-5 parts of binder, 20-35 parts of disintegrant, 1-5 parts of lubricant, 3-8 parts of auxiliary agent. The invention has the advantages of good dispersibility, high disintegration rate and dissolution rate, and excellent stability of related substances.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical preparations, in particular to an atorvastatin calcium tablet and a preparation process thereof. Background technique [0002] Atorvastatin calcium (Atorvastatin Calcium) belongs to the inhibitor of hydroxymethylglutaryl CoA (HMG-CoA) reductase, which can reduce the concentration of cholesterol in plasma and serum lipoprotein by inhibiting the biosynthesis of HMG-COA reductase and cholesterol in the liver , and enhance the uptake and metabolism of low-density lipoprotein by increasing the hepatic low-density lipoprotein receptors on the cell surface. Atorvastatin calcium can effectively reduce plasma total cholesterol, low-density lipoprotein cholesterol, apolipoprotein and triglyceride in patients with homozygous and heterozygous familial hypercholesterolemia, nonfamilial cholesterolemia and mixed lipid metabolism disorders At the same time, the levels of high-density lipoprotein choleste...
