Abstract
A large group of lipophilic, pharmacologically active compounds can be effectively delivered across intact skin by applying them topically in a binary, penetration-enhancing vehicle containing (1) a C.sub.3 -C.sub.4 diol, diol ester, or diol ether and (2) a cell envelope-disordering compound. This vehicle provides surprising enhancement of skin penetration for the pharmacological active, compared to either component alone.
