There is increasing evidence that epidermal carboxylesterase may be involved in the stereoselective hydrolysis of prodrugs in percutaneous absorption. The present study was designed to evaluate the stereoselective characteristics and mechanisms of ketoprofen ethyl ester hydrolysis by epidermal carboxylesterase expressed
