While the precise biological actions of sildenafil in the heart are not fully understood, the drug is known to work by stopping the action of an enzyme, called phosphodiesterase 5 , the researcher says. This enzyme is involved in the breakdown of a key molecule, cyclic GMP, which helps control stresses and limit overgrowth in the heart. PDE5A is also the biological pathway blocked in the penis by sildenafil to promote the relaxation of blood vessels and maintain erections. The researchers’ findings, which appear in the journal Circulation online Oct. 24, are believed to be the first confirmation in humans that sildenafil has a direct effect on the heart.

Sildenafil is also approved to treat pulmonary arterial hypertension, which is high blood pressure in the vessels that carry blood to the lungs. The drug treats this condition by relaxing blood vessels in the lungs, which allows blood to flow more easily, according to the NIH.

The best time to take sildenafil is about 1 hour before sexual activity, but you can take the medication any time from 4 hours to 30 minutes before sexual activity.

Simply said, as far as exercise capacity, the drug could be considered a treatment in response to the effects of high altitude as opposed to an ergogenic, or performance-enhancing, aid.
