Problems solved by technology

The imported polyene phosphatidylcholine capsules are waxy viscous substances that are heated and liquefied, filled into hard capsule shells by special filling equipment, and hard capsule preparations whose contents are waxy viscous substances are formed after cooling. The disadvantage is that it needs expensive special equipment that is not yet domestically produced. The price of a set of imported equipment is not less than 8 million yuan, and the products obtained by this preparation process cannot effectively isolate air and moisture; at the same time, the temperature during storage or transportation is too high. High, its contents will soften, thereby reducing the safety of the drug during storage and transportation
[0006] In the prior art, Chinese patent application 200910079858.0 discloses an oral solid preparation containing polyene phosphatidylcholine and its preparation method, which consists of raw materials polyene phosphatidylcholine, antioxidants and related auxiliary materials necessary for molding the corresponding preparations Composition, the polyene phosphatidylcholine is cryogenically frozen and pulverized to make different dosage forms. The disadvantage is that it requires ultra-low temperature freezing equipment, high energy consumption and is not conducive to industrial operation.
Chinese patent applications 200510037429.9 and 200510094998.7 disclose freeze-dried powder for injection of polyene phosphatidylcholine, which also requires ultra-low temperature freezing equipment, high energy consumption and unfavorable for industrial operation

Abstract

The invention relates to an oral solid preparation containing polyene phosphatidyl choline and a preparation method thereof. The preparation method comprises the following steps: dissolving polyene phosphatidyl choline in ethanol; adequately mixing the polyene phosphatidyl choline with a matrix, an antioxygen and a sorbefacient in a protective state; carrying out vacuum drying and volatilizing to remove ethanol, and preparing pellets by a pill dropping machine; and packaging the pellets coated or packing in hard capsules or tabletting and coating to obtain the oral solid preparation containing polyene phosphatidyl choline. The oral solid preparation containing polyene phosphatidyl choline provided by the invention can enhance the stability of polyene phosphatidyl choline, reduce the gastrointestinal irritation by the medicine and improve the dissolving-out performance of polyene phosphatidyl choline, so that the equipment cost is saved to the benefit of industrialized production.

Description

technical field [0001] The invention relates to the field of pharmaceutical preparations, in particular to an oral solid preparation containing polyene phosphatidylcholine and a preparation process thereof. Background technique [0002] At present, there are tens of millions of patients with various liver diseases in my country, hundreds of millions of hepatitis virus carriers, and hundreds of thousands of people who die each year due to liver diseases. The task of preventing and treating liver diseases in my country is very arduous. There are few drugs that are good and have low side effects, especially those that are effective for various liver diseases and have a broad spectrum for treating liver diseases. [0003] Polyene phosphatidylcholine is a hepatobiliary disease treatment drug developed by SANOFI AVENTIS. It is mainly used clinically for various types of liver diseases, such as: hepatitis, chronic hepatitis, liver necrosis, cirrhosis, Hepatic coma (including prodro...
