Abstract
The topical drug delivery composition and method of the present invention provides a composition and method for delivering amounts of diclofenac effective for treating inflamed and/or painful joints or muscles percutaneously via a gel. Diclofenac sodium is solubilized in a mixture of water, a low molecular weight alcohol, and a glycol. In the present invention, the transdermal flux of diclofenac is unexpectedly enhanced by the addition of an ether alcohol and a fatty alcohol ester. The transdermal flux can be further enhanced by the addition of a glycol such as hexylene glycol.
