Abstract

The invention discloses a simethicone dry suspension and a preparation method thereof. The simethicone dry suspension contains simethicone of 4% in mass percentage and a carrier which is pharmaceutically acceptable. The preparation method is simple and convenient in operation, low in cost and suitable for industrialized production. The simethicone dry suspension has the advantages of good taste, uniform distribution, high dissolubility and stable quality, is more advantageous and convenient than conventional liquid simethicone suspensions and emulsions in aspects of packaging, carrying and transporting, is used for treating diseases like abdominal distension, abdominal discomfort, indigestion and postoperative abdominal distension caused by abdominal gas gathering and has good application prospect.

Description

technical field [0001] The invention belongs to the field of pharmaceutical preparations, in particular to simethicone dry suspension, and also relates to a preparation method of simethicone dry suspension.
