Zusammenfassung:	A dosage form that coadministers a drug and a percutaneous absorption enhancer to a defined area of the skin. The dosage form comprises a body that contains supplies of drug and enhancer and has a basal surface that contacts the area of skin and transmits the drug and enhancer to the area for absorption thereby. The drug is provided to the basal surface at a rate at least as great as the rate at which the skin is able to absorb the drug whereas the enhancer is via a rate controlling means at a substantially constant rate that increases the permeability of the treated area of skin to the drug to a level at which the drug is absorbed at a therapeutically effective rate. A preferred embodiment delivers estradiol and employs ethanol as an enhancer, the ethanol delivery rate being about 100-800 mcg/hr/cm2 of skin surface.
