Problems solved by technology

[0013] CN101804029A discloses a kind of atorvastatin liposome, in order to overcome the dosage form existing in the prior art, adopt simple atorvastatin calcium crude drug without any modification to add the alkaline agent that pH is greater than 5 to make and this The stability and bioavailability of the preparation are poor, and the defects of the pharmacological activity of atorvastatin cannot be effectively brought into play. It is made into liposomes of atorvastatin or a pharmaceutical salt thereof, the liposomes obtained above and its None of atorvastatin calcium in fixed formulations overcomes crystalline form leading to bioavailability issues

Abstract

The invention discloses a solid preparation of atorvastatin calcium liposome. The preparation is prepared from the atorvastatin calcium liposome and other pharmaceutically common auxiliary materials, wherein the atorvastatin liposome is prepared from the following components in parts by weight: 1 part of atorvastatin calcium, 2-5 parts of phospholipid and 0.8-3 parts of additive. The atorvastatin solid preparation prepared from the liposome has the advantages that the dissolution rate is increased, the stability and bioavailability are greatly improved, the product quality of the preparation is improved and the toxic and side effect is reduced.

Description

technical field [0001] The present invention relates to an atorvastatin calcium liposome preparation, especially an amorphous atorvastatin calcium liposome preparation maintaining high bioavailability, and further relates to an atorvastatin calcium liposome solid preparation and its preparation method, which belongs to the field of medical technology. Background technique [0002] Cardiovascular disease is one of the most common and serious diseases that endanger human health. It has the characteristics of "high incidence, high disability rate, high mortality rate, high recurrence rate and many complications". At present, there are more than 270 million patients with cardiovascular and cerebrovascular diseases in my country. In recent years, domestic and foreign guidelines for the prevention and treatment of hypertension have indicated that the blood pressure of hypertensive patients should be actively and persistently lowered to below 140 / 90 mmHg (the best should be lowered...
