The present invention relates generally to compositions or formulations for transdermal or transmucosal administration of anti-cholinergic agents such as oxybutynin. The invention utilizes a novel delivery vehicle and is a substantially malodorous-free and irritation free transdermal formulation which is substantially free of long chain fatty alcohols, long-chain fatty acids, and long-chain fatty esters. A method is disclosed for administering such formulations to a person in need thereof while reducing the incidences of peak concentrations of drug and undesirable side effects associated with oral anti-cholinergics.
