Abstract: A pharmaceutical composition contains an acid addition salt of a basic drug and a fatty acid or bile acid. The acid addition salts thus formed exhibit enhanced transmucosal and transdermal penetration of the basic drug. The acid addition salts, an inclusion complex containing said salts and a use of said salts are also disclosed.

Abstract: A process for the optical resolution of racemic 3-(p-chlorophenyl)glutaramide (GAM) into its R isomer R--COOH and its S isomer S--COOH, which process includes the steps of either:(1) reacting racemic 3-(p-chlorophenyl)-glutaramide dissolved in a suitable solvent with S-(-)-.alpha.-methylbenzylamine of the formula H.sub.2 N--S'(2) precipitating out of the solution of step (1) R--CO.sub.2.sup.-.H.sub.3.sup.+ N--S';(3) dissolving the precipitate of step (2) in water, with the addition of a suitable acid; and(4) precipitating out of the solution of step (3) R--COOH; or(5) reacting racemic -3-(p-chlorophenyl)-glutaramide dissolved in a suitable solvent with R-(+)-.alpha.-methylbenzylamine of the formula H.sub.2 N--R';(6) precipitating out of the solution of step (5) S--CO.sub.2.sup.-.H.sub.3.sup.+ N--R';(7) dissolving the precipitate of step (6) in water, with the addition of a suitable acid, and(8) precipitating out of the solution of step (7) S--COOH.
