1 Abstract

An anhydrous transdermal composition is disclosed comprising in a 20 to 100% lyotropic liquid crystalline arrangement: 5 to 15 weight % of optically active or racemic N-methyl-N-(1-phenyl-2-propyl)-2-propynylamine or N-methyl-N-{1-(4-fluorophenyl)-2-propyl}-2-propynylamine or a pharmaceutically acceptable salt thereof; 40 to 70% by weight of liquid polyethylene glycol; 10 to 20% by weight of solid polyethylene glycol; 2 to 30% by weight of a nonionic surface active agent; 2 to 20% by weight of propylene glycol, and if desired, 0.5 to 2% by weight of a polymer, the a value of which is greater than 0.6, and optionally, in an amount needed up to 100% an emulsifying agent.
