Future Directions

The incidence of disorders and dysfunctions of the urogenital tract including the kidney are increasing with the aging of the population. Drug treatments for both bona fide organic disorders (endometriosis, prostatitis, BPH, incontinence, BOO) and those more psychologically related (sexual dysfunction) are limited in their efficacy and side effect liabilities and perhaps with new insights into potential genetic causes of these disorders, may be treated via newer targets that have a lesser impact on cardiovascular system function.

The more effective treatment of the spectrum of disorders related to women's health has spurred initiatives both within the industry and government. The latter, the National Institutes of Health's Women's Health Initiative, now 15 years old has spent $725 million in studying 161000 females. It is reportedly plagued with flawed clinical trial designs, patient enrollment criteria, and data misinterpretation, and has raised issues regarding the effectiveness of hormone therapy in the treatment of postmenopausal orders,21 confounding the search for improvements on existing medications. Similarly, the evolution of drug treatments for the lifestyle disorders of ED and FSD, like that of nonmorbid obesity, are confounded by the major psychological component of each making it challenging to prioritize the targeting of new drugs for peripheral versus central targets.
