Abstract

The invention provides a new-type cataplasma matrix and its preparing method. The formulation is: carbomer 2.0-10.0 shares, arabic gum 5.0-20.0 shares, glycerin 20.0-60.0 shares, Polyethylene Glyco 3.0-10.0 shares, polyvidone 10.0-40.0 shares, glutin 10.0-40.0 shares, sodium hydroxide 1.0-4.0 shares, ultrapure water 70.0-120.0 shares, azone 0.0-6.0 shares, camphor 0.0-5.0 shares, menthol crystal 0.0-5.0 shares, or azone 0.0-6.0 shares, capsicum extract 0.0-5.0 shares. The inventive cataplasma matrix has a good adhesive force to skin, a storage stability in a temperature and humidity change, a good compatibility with different medicine, a wide application area and fits for the free activity of the affected part and a high dosage medicine. The cataplasma matrix can be taken off and adhered again and again without pain and residue.

Description

technical field [0001] The invention relates to a novel cataplasm matrix and a preparation method of the cataplasm matrix. The cataplasm matrix relates to a matrix that can be used for making cataplasms and various external medical patches. Background technique [0002] Transdermal drug delivery system is the frontier direction in the current pharmaceutical field, and drug absorption through the skin has many advantages. Traditional plasters (soft plasters, black plasters) are all based on fat-soluble materials, which have serious defects in application, such as small drug load, poor transdermal performance, allergies, rashes, adhesion of hair, and contamination of clothing. At that time, the medical circles in Europe and Japan were all committed to improving the traditional external patch, and tried to develop a kind of patch with large drug content, good transdermal effect, controllable and slow release of drug components, good air permeability, and no irritation to the sk...
