| titleOfInvention | Chubuterol transdermal patch and preparation method thereof |
| abstract | The invention belongs to the technical field of medicine and provides a tranbuterol transdermal patch and a preparation method thereof. The patch is composed of a backing layer, a drug-loaded pressure-sensitive adhesive layer and a release layer, and the drug-loaded pressure-sensitive adhesive layer contains tetrabuterol free base or its organic acid ion-pair complex, pressure-sensitive adhesive and percutaneous absorption promotion agent, wherein the amount of tetrabuterol free base or its organic acid ion-pair complex accounts for 2-15wt%, the amount of pressure-sensitive adhesive accounts for 70-95wt%, and the amount of transdermal absorption enhancer accounts for 0-20wt%. In the terrol organic acid ion-pair complex, the molar ratio of tetrabuterol free base to different organic acids is 1:1. The tranbuterol transdermal patch provided by the invention can increase the transdermal penetration amount of the drug, make the drug play a better role, and greatly improve the utilization rate of the patch. |
