As research continues, the scope of Viagra's impact on medicine may expand even further. In conclusion, Viagra has made a significant impact on the treatment of erectile dysfunction since its introduction. For instance, it has shown potential benefits in treating pulmonary arterial hypertension (PAH), a rare but serious heart condition. It is marketed under the brand name Revatio for this purpose. Beyond its primary use in treating ED, Viagra has also been explored for other medical conditions.

In PAH, Viagra helps relax blood vessels in the lungs, improving blood flow and reducing the heart's workload. While Viagra has been a game-changer in sexual health, it is not without potential side effects. More serious but rare side effects can include priapism (a prolonged and painful erection) and cardiovascular events such as heart attack or stroke, particularly in those with pre-existing heart conditions. Common adverse effects include headaches, flushing, indigestion, nasal congestion, and impaired vision.

The mechanism of action for Viagra involves the blocking of the PDE5 enzyme, which is predominantly found in the penis. The active ingredient in Viagra, sildenafil, belongs to a class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors.
