A method is provided for increasing the permeability of skin or mucosal tissue to transdermally administered oxybutynin. The method involves use of a specified amount of a hydroxide-releasing agent, the amount optimized to increase the flux of the drug through a body surface while minimizing the likelihood of skin damage, irritation or sensitization. Formulations, drug delivery systems and methods of treatment are provided as well.

A method is provided for increasing the permeability of skin or mucosal tissue to topically or transdermally administered pharmacologically or cosmeceutically active agents. The method involves use of a specified amount of a hydroxide-releasing agent, the amount optimized to increase the flux of the active agent through a body surface while minimizing the likelihood of skin damage, irritation or sensitization. Topically applied formulations and drug delivery devices employing hydroxide-releasing agents as permeation enhancers are provided as well.

Methods are provided for enhancing the permeability of skin or mucosal tissue to topical or transdermal application of pharmacologically or cosmeceutically active agents. The methods entail the use of a base in order to increase the flux of the active agent through a body surface while minimizing the likelihood of skin damage, irritation or sensitization. The permeation enhancer can be an inorganic or organic base. Compositions and transdermal systems are also described.
