Problems solved by technology

However, when the amount of drug powder accounts for a large proportion of the preparation or when the preparation is produced using traditional Chinese medicine or natural medicine extracts, the emulsification system formed by the general surfactant cannot meet the stability requirements, and matrix phase separation is prone to occur, which will destroy the uniformity and stability of the preparation.

Abstract

The invention provides a matrix for a suppository or a paste medicine and a method preparing the suppository or the paste containing the matrix. The matrix comprises (1) fat soluble matrix and (2) polyethylene glycol fatty acid ester. The invention also provides application of the matrix on preparing the suppository or the paste medicine for treating prostatitis. When being used to manufacture the suppository or the paste, the matrix of the invention can carry high dose and at the same time the suppository or the paste containing the matrix can bear high temperature in the transportation process and keep good stability.

Description

technical field [0001] The invention relates to a matrix of suppository or ointment medicine and a preparation method of the matrix, in particular to a matrix of suppository or ointment medicine for treating prostatitis and a preparation method thereof. Background technique [0002] A suppository is a solid preparation that, when applied to the rectum, urethra, and vagina, etc., softens or melts at body temperature, or dissolves in the local mucous membrane, allowing the drug to be absorbed into the body through the mucous membrane. In the existing suppositories, mixed fatty acid glycerides are often used as the suppository matrix, which is less irritating to the mucous membranes, but when mixed with water-soluble powders, some pharmaceutical surfactants need to be added to achieve drug in the matrix. Dissolve, disperse, and form water-in-oil or oil-in-water emulsion systems. However, when the amount of drug powder accounts for a large proportion of the preparation or when ...
