Viagra, also known as sildenafil, primarily treats erectile dysfunction (ED). It works by increasing blood flow to the penis, facilitating an erection. This effect occurs when sexually stimulated.
How Viagra Works
Sildenafil inhibits an enzyme called phosphodiesterase-5 (PDE5). This inhibition allows for increased levels of cyclic GMP, a molecule crucial for achieving and maintaining an erection. The result? Improved blood flow and the ability to achieve and sustain an erection sufficient for satisfactory sexual activity.
Other Uses
Beyond ED, Viagra has shown efficacy in treating pulmonary arterial hypertension (PAH). PAH is a condition causing high blood pressure in the arteries leading to the lungs. Viagra helps lower this blood pressure by relaxing the blood vessels.
Consult your doctor before using Viagra, especially if you have underlying health conditions or are taking other medications. They can assess your suitability and help manage potential side effects.
