Pharmacotherapeutic management of erectile dysfunction

Erectile dysfunction is a common condition in aging men and significantly affects their quality of life and interpersonal relationships. Its prevalence and incidence are associated with aging, lifestyle factors and cardiovascular comorbidities. Preoccupation with male virility has been present for centuries, and a wide variety of herbs and potions have been used to treat any sexual deficiencies. Recent major advances in understanding of erectile physiology and pathophysiology led to development of currently available systemic and local pharmacotherapies. They are designed to work either centrally or peripherally and to either suppress anti-erectile mechanisms, enhance the pro-erectile ones or influence both. Since all the current formulations have variable safety and efficacy profiles, the search for highly specific, simple, convenient and clinically effective impotence treatments or prophylactics continues.
