What is sildenafil?
In an animal model of ventricular hypertrophy induced by pressure overload, sildenafil administration prevented the development of ventricular hypertrophy and, in animals with established hypertrophy, reversed the hypertrophy. The postulated mechanisms are improved calcium handling, sildenafil-induced increase in cGMP concentration, and thus increase in cGMP-dependent protein kinase activity, which in turn appears to lead to a decrease in downstream hypertrophy signaling. At the same time, animals treated with sildenafil showed an improvement in ventricular systolic function.96,106 These findings are very encouraging and suggest that sil-denafil may successfully and safely decrease pulmonary artery pressures in patients with systolic heart failure and improve symptoms and exercise capacity even in patients with heart failure but without significant pulmonary hypertension.103 Larger prospective clinical trials are needed to confirm these findings and to evaluate the benefit of this agent on morbidity and mortality outcomes in patients with systolic heart failure. Moreover, the evidence that sildenafil may reverse hypertrophy suggests that it may have a role in the treatment of diastolic heart failure, as reviewed in detail in Chapter 48.

MeSH terms
Medical causes of impotence include diabetes and circulatory, neurological, or urological conditions. Penile erection is caused by the engorgement of the penis with blood. This engorgement occurs when the blood vessels delivering blood to the penis increase the delivery of blood and the blood vessels carrying blood away from the penis decrease the removal of blood. Under normal conditions, sexual stimulation leads to the production and release of nitric oxide in the penis. Nitric oxide then activates the enzyme, guanylate cyclase, which causes the production of cyclic guanosine monophosphate (cGMP).
Other Medical Problems
It is the cGMP that is primarily responsible for the erection by affecting the amount of blood that the blood vessels deliver and remove from the penis. Viagra inhibits an enzyme called phosphodiesterase-5 (PDE5) which destroys the cGMP. Thus, Viagra prevents the destruction of cGMP and allows cGMP to accumulate and persist longer. The longer cGMP persists, the more prolonged the engorgement of the penis. The FDA approved Viagra in March 1998.
