Abstract

The invention discloses a solid preparation of a compound ammonia phenol renin medicine composition liposome and a preparation method thereof. The method comprises that the compound ammonia phenol renin medicine composition liposome is prepared by acetaminophen, anhydrous caffein, phenylephrine hydrochloride, chlorpheniramine maleate, vitamin B1, egg yolk lecithin acyl serine, phosphatidyl ethanolamine and octadecylamine which are selected according to specified weight ratio, and then the solid preparation is prepared by the compound ammonia phenol renin medicine composition liposome through an ordinary preparation method. The solid preparation of the liposome is high in encapsulation and even in particle size, improves quality of a preparation product, reduces toxic and side effects, andis suitable for industrialized production. In addition, the preparation method is simple, and the medicine is reserved in blood circulation for a long time.

Description

technical field [0001] The invention relates to a liposome solid preparation of a compound aminophenol renin pharmaceutical composition and a preparation method thereof. The active ingredients include acetaminophen, anhydrous caffeine, phenylephrine hydrochloride, chlorpheniramine maleate and vitamin B 1 , belonging to the field of medical technology. Background technique [0002] The active ingredients of compound aminophenol renin pharmaceutical composition liposome solid preparation are acetaminophen, anhydrous caffeine, phenylephrine hydrochloride, chlorpheniramine maleate and vitamin B 1 The combination of paracetamol can inhibit the synthesis of prostaglandins and produce antipyretic and analgesic effects; caffeine is a central stimulant, and it can strengthen antipyretic and analgesic effects when used in combination with antipyretic and analgesic drugs; phenylephrine hydrochloride can Shrink the capillaries of the upper respiratory tract, eliminate the congestion of...
