Abstract

The present invention relates to an artemether cataplasma and the application. The cataplasma is prepared by artemether and proper excipients. The artemether cataplasma of the present invention is composed of three parts of a back lining layer, a paste body containing drug and a cover lining layer. The major part is the paste body containing drug which is prepared by artemether, adhesives, fillers, transdermal enhancers, moisturizing agents and other excipients according to a certain mixing ratio, each paste contain 20mg to 300mg of artemether. The cataplasma has the anti-fever effect and is characterized by fast acting, good moisture retention performance, good air permeability and comfortable usage, the product of the present invention has easy usage, small irritation on the skin and high compliance of the patients.

Description

technical field [0001] The present invention relates to the technical field of medicines, in particular to an external dosage form of artemether, which can be used for children and adults, and has a good therapeutic effect on fever caused by various infectious diseases and non-infectious diseases. its application. Background technique [0002] Catapult is an external preparation that dissolves or mixes drugs in a natural or synthetic water-soluble polymer matrix and spreads them on the backing material for sticking on the skin. It can act systemically or locally through transdermal absorption. It is also a transdermal drug delivery preparation, and its prototype is "poultica". Due to the rapid development of modern fine chemical industry and polymer material science, more excipients with superior performance have been provided for pharmacy. Therefore, cataplasm was first successfully developed by Japan in the 1970s. Up to now, a large number of cataplasms have been launch...
