Procedure

95% ethanol (USP) was diluted with water (USP), glycerin (USP), and glycerol monooleate (Eastman Chemical, Kingsport N.Y.) to provide a final solution at ethanol/water/glycerin/glycerol monooleate percent ratios of 35/59/5/1, respectively. Oxybutynin free base was then dissolved into the above solution to a concentration of 10 mg/gram. The resultant solution was then gelled with 1% hydroxypropyl cellulose (Aqualon, Wilmington, Del.) to provide a final oxybutynin gel. One to two grams of the above gel is applied topically to approximately 200 cm2 surface area on the chest, torso, and or arms to provide topical administration of oxybutynin.
