  • Patent number: 6197782
    Abstract: Disclosed are nitrosated and/or nitrosylated phosphodiesterase inhibitors having the formula NOn-PDE inhibitor where n is 1 or 2. The invention also provides compositions comprising such compounds in a pharmaceutically acceptable carrier. The invention also provides a composition comprising a therapeutically effective amount of an phosphodiesterase inhibitor (PDE inhibitor), which can optionally be substituted with at least one NO or NO2 moiety, and one to ten fold molar excess of a compound that donates, transfers or releases nitrogen monoxide as a charged species, i. e., nitrosonium (NO+) or nitroxyl (NO−), or as the neutral species, nitric oxide (NO.) or which stimulates endogenous EDRF production. The invention also provides compositions comprising such compounds in a pharmaceutically acceptable carrier. The invention also provides methods for treating sexual dysfunctions in males and females.
