Abstract
A delivery vehicle for topical pharmaceutical formulations that include a C2 to C4 alkanol, a polyalcohol, and a monoalkyl ether of diethylene glycol present in relative amounts sufficient to provide permeation enhancement of an active agent through mammalian dermal or mucosal surfaces. Preferably, the delivery vehicle as well as the formulations that contain it are substantially free of long-chain fatty alcohols, long-chain fatty acids and long-chain fatty esters in order to avoid potential undesirable odor and irritation effects caused by such compounds during use of the formulation. Without these additives, use of the formulations is facilitated and patient compliance is greater
