Abstract
Novel external medications comprise, as essential components, the following three components (A) to (C): PA0 (A) an .alpha.-monoglyceryl ether represented by the following formula (I): ##STR1## wherein R means an alkyl or alkenyl group having 10 - 24 carbon atoms; (B) a physiologically active material; and PA0 (C) an oily material. The external medications have extremely high skin occlusive properties and significantly-improved absorptivity of phosiologically active materials. Therefore, a smaller amount of the medications compared with the conventional ones can give sufficient pharmacological effects and thus side effects can be reduced. The external medications may contain physiologically active materials such as drugs, growth hormones and the like, which are expected to show pharmacological effects upon their percutaneous absorption.
