Abstract

The invention provides an epinastine hydrochloride transdermal patch. The epinastine hydrochloride transdermal patch is composed of a back lining layer, a drug containing layer and a anti-adhesion layer, wherein the drug containing layer is composed of, by weight percentage, 0.5-10% of epinastine hydrochloride, 60-90% of pressure-sensitive adhesives, 5-20% of plasticizer and 4-30% of transdermal enhancer. The preparation method of the epinastine hydrochloride transdermal patch comprises stirring and dissolving the plasticizer and the transdermal enhancer, sequentially add in and uniformly mixing the epinastine hydrochloride and the pressure-sensitive adhesives, performing degassing and drying processes, applying anti-adhesion materials to form the anti-adhesion layer, drying the anti-adhesion layer and covering the back lining layer to obtain the epinastine hydrochloride transdermal patch. The epinastine hydrochloride transdermal patch is prepared by mixing and matching water-soluble polymer materials and main drugs and is low in dosage; the epinastine hydrochloride transdermal patch can be prepared into thin patches, which are stable in properties, safe, free from irritation and good in skin tolerance; compared with traditional oral medicines, the epinastine hydrochloride transdermal patch is good in effects, beneficial to absorption by patients and capable of avoiding first-pass effects of liver of the patients.

Description

technical field [0001] The invention relates to the field of medicine preparation, in particular to an epinastine hydrochloride transdermal patch and a preparation method thereof.
