Abstract
Pharmaceutical formulations, transdermal drug delivery devices, and methods of drug delivery using the formulations and devices of the invention are disclosed which make it possible to enhance the rate of transdermal drug delivery of pharmaceutically active compounds and in particular molsidomine. The rate of drug delivery is increased by using absorption promoters which include monoalkyl phosphates and salts thereof alone or in combination with other absorption promoters such as polyhydroxyl esters, longchain fatty acids, polyhydroxyl alcohols and terpenes. Particular combinations of monoalkyl phosphates with one or more additional absorption promoters provides synergistic effects with respect to enhancing the rate of drug delivery of certain pharmaceutically active drugs such as molsidomine.
