Abstract
alkanol, a polyalcohol, and a permeation enhancer of monoalkyl ether of diethylene glycol present in an amount sufficient to provide permeation enhancement of the active agent through dermal or mucosal surfaces. The formulation is substantially free of long-chain fatty alcohols, long-chain fatty acids, and long-chain fatty esters in order to avoid undesirable odor and irritation effects caused by such compounds during use of the formulation. Also, the active agent is testosterone that is present in an amount of about 1%, the alkanol is ethanol that is present in an amount of about 46.28% to about 47.5% of the formulation; the polyalcohol is propylene glycol that is present in an amount of about 6% of the formulation; and the permeation enhancer is diethylene glycol monoethyl ether that is present in an amount of about 5% of the formulation.
