| description | Methods, formulations, and drug delivery systems are provided for enhancing the flux of a transdermally administered hydrophilic drug using a basic permeation enhancer composition. The enhancer composition contains an inorganic hydroxide and a weaker, nitrogenous base, wherein the bases are selected such that a 0.1M aqueous solution of the nitrogenous base has a pH that is about 1.0 to about 6.5 lower than the pH of a 0.1M aqueous solution of the inorganic hydroxide. Additionally, the molar ratio of the nitrogenous base to the inorganic hydroxide in the enhancer composition is in the range of about 0.5n:1 to about 20n:1, where n is the number of hydroxide ions per molecule of the inorganic hydroxide. |
