Preparation process of cold compress gel

Abstract

The invention relates to a preparation process of cold compress gel. The preparation process comprises the following steps: determining the dosage of each raw material according to the total preparation demand, preparing component A powder, preparing a component A concentrated solution, preparing first extract, preparing component B powder, preparing a component B concentrated solution, preparing second extract, and mixing the first extract and the second extract to prepare the cold compress gel. According to the preparation process, a preset demand matrix S0 and a preset particle size matrix R0 are established when the component A raw material is ground, the preset particle size when the component A powder is prepared is determined according to the actual use demand of to-be-prepared cold compress gel, the corresponding powder particle size is determined according to the actual use demand of the to-be-prepared cold compress gel, and effective components meeting the demand can be efficiently extracted in the subsequent process of extracting effective components of the component A powder, thereby effectively improving the preparation efficiency of the method for the cold compress gel.

Description

technical field [0001] The invention relates to the technical field of cold compress gel preparation, in particular to a preparation method of cold compress gel. Background technique [0002] As a transdermal drug delivery preparation, the cold compress gel can absorb the drug through the skin and play a therapeutic role for corresponding diseases; on the other hand, after the gel is attached to the skin, the body surface skin temperature is transmitted to the cold gel , the heat is absorbed by the water molecules in the gel, and a large amount of heat is taken away through the evaporation of water, thereby reducing the local temperature of the skin on the body surface, and reducing the burning sensation, pain, swelling and sensitivity of the skin. [0003] The cold compress gel preparation process in the prior art is by grinding the drug into powder and extracting the active ingredient in the drug powder, and mixing the active ingredient with the paste carrier to complete t...
