Claims
- 1. A method for enhancing penetration of systemically active agents through the skin or mucosal membranes and into the bloodstream of humans and animals, said method comprising the topical administration of effective amounts of a systemically active agent and of a membrane penetration enhancer having the structural formula ##STR7## 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, ##STR8## wherein R" is H or halogen, and salts thereof.
- 2. The method of claim 1 wherein R is hydrogen or a lower alkyl group, R' is H, X is oxygen, and A is a divalent radical represented by the general formula --(CH.sub.2).sub.n wherein n is 0 to 17.
- 3. The method of claim 2 wherein n is 4 to 16.
- 4. The method of claim 3 wherein n is 10.
- 5. The method of claim 1 wherein the systemically active agent is therapeutic agent.
- 6. The method of claim 5 wherein the administration is concurrent.
- 7. The method of claim 1 wherein the membrane penetration enhancer is selected from the group consisting of N-(1-oxodecyl)morpholine, N-(1-oxodecyl)-piperazine, 1,4-bis(1-oxodecyl)piperazinium chloride and N-(1-oxodecyl)thiomorpholine.
- 8. The method of claim 1 wherein the systemically active agent is selected from the group consisting of haloperidol, isosorbide dinitrate, nitroglycerin, estradiol, clonidine, propranolol, indomethacin, nifedipine, nicardipine, diclorofenac and metaproterenol.
- 9. The method of claim 7 wherein the systemically active agent is selected from the group consisting of haloperidol, isosorbide dinitrate, nitroglycerin, estradiol, clonidine, propranolol, indomethacin, nifedipine, nicardipine, diclorofenac and metaproterenol.
