Co-administration of a prostaglandin and an androgenic agent in the treatment of female sexual dysfunction

This invention relates generally to methods and pharmaceutical formulations for treating female sexual dysfunction, and more particularly relates to vaginal, vulvar and/or urethral administration of a vasoactive agent, such as a prostaglandin, in such treatment. The invention further relates to additional methods of using the present pharmaceutical formulations, including, but not limited to, the prevention of yeast infections and the improvement of vaginal muscle tone. Methods and formulations for treating female sexual dysfunction are provided. A pharmaceutical composition formulated so as to contain a selected vasoactive agent is administered to the vagina, vulvar area or urethra of the individual undergoing treatment. Suitable vasoactive agents are vasodilators, including naturally occurring prostaglandins, synthetic prostaglandin derivatives, endothelial-derived relaxation factors, vasoactive intestinal polypeptide agonists, smooth muscle relaxants, leukotriene inhibitors, and others. The formulations are also useful for preventing the occurrence of yeast infections, improving vaginal muscle tone and tissue health, enhancing vaginal lubrication, and minimizing excess collagen deposition. A clitoral drug delivery device is also provided.
