This invention provides compositions for enhancing penetration of physiologically active agents through the skin or mucosal membranes and for retaining these agents in body tissues, said composition comprising effective amounts of a physiologically-active agent and a compound represented by the general formula ##STR1## wherein X may represent sulfur, oxygen or nitrogen; a and b may be 0 or 1, c may be 0, 1 or 2, except that when X is oxygen, a, b and c are 0, when X is nitrogen c is 0 and only one of a or b is 1, and when X is sulfur a and b are 0; A is a branched or a straight chain, divalent aliphatic radical having from 0 to 2 double bonds; R' is selected from the group consisting of H, a lower alkyl group having from 1 to 4 carbon atoms, phenyl, lower alkyl or halogen substituted phenyl, acetamido, halogen, piperidinyl, lower alkyl or halogen substituted piperidinyl, carbalkoxy, carboxamide, and alkanoyl; and R is hydrogen or a lower alkyl group having from 1 to 4 carbon atoms, ##STR2## wherein R" is H or halogen, and salts, e.g. acid or quaternary derivatives, thereof. These compositions are useful in topical or transdermal applications of the physiologically-active agent.
这项发明提供了用于增强生理活性剂穿透皮肤或黏膜膜并在体内组织中保留这些剂量的组合物,所述组合物包括生理活性剂和由一般式##STR1##表示的化合物的有效量,其中X可以代表硫、氧或氮;a和b可以是0或1,c可以是0、1或2,但当X为氧时,a、b和c都为0,当X为氮时,c为0,a或b中只有一个为1,当X为硫时,a和b都为0;A是具有0到2个双键的支链或直链的二价脂肪族基;R'选自H、具有1到4个碳原子的低烷基基团、苯基、低烷基或卤代苯基、乙酰胺基、卤素、哌啶基、低烷基或卤代哌啶基、羰基醇酯、羧酰胺和烷酰;R为氢或具有1到4个碳原子的低烷基基团,##STR2##其中R"为H或卤素,以及其盐,例如酸性或季铵衍生物。这些组合物在生理活性剂的局部或经皮应用中是有用的。
