Transdermally delivered aspirin

摘要

An aspirin formulation suitable for transdermal delivery has powdered aspirin dissolved in relatively high concentrations in a solution composed of a pharmaceutically acceptable solvent and an organic amine a. The primary solvent is preferably an organic hydroxy compound having good transdermal propellant characteristics. The resulting aspirin solution is nonirritating to the skin and exhibits good stability over the useful life of a transdermal delivery patch. A patch suitable for delivering the aspirin solution to the skin of a patient is also described.
