Viagra, or sildenafil citrate, primarily treats erectile dysfunction (ED). It works by increasing blood flow to the penis, facilitating an erection when sexually stimulated. This effect arises from inhibiting an enzyme called phosphodiesterase-5 (PDE5).
How Viagra Works
PDE5 normally breaks down cGMP, a molecule responsible for relaxing penile muscles. Viagra’s inhibition of PDE5 allows cGMP levels to remain high, promoting relaxation and blood vessel dilation. This increased blood flow is key to achieving and maintaining an erection.
Beyond Erectile Dysfunction
While widely known for ED, Viagra also finds use in treating pulmonary arterial hypertension (PAH), a condition causing high blood pressure in the arteries leading to the lungs. It improves blood flow to the lungs, easing breathing difficulties. Always consult a doctor before using Viagra for any condition.
