Viagra, also known as sildenafil, treats erectile dysfunction (ED) by increasing blood flow to the penis. This allows men to achieve and maintain an erection sufficient for satisfactory sexual intercourse.
It works by inhibiting an enzyme called phosphodiesterase-5 (PDE5). This enzyme normally breaks down cGMP, a molecule that relaxes smooth muscles in the penis. By blocking PDE5, Viagra increases cGMP levels, leading to vasodilation and improved blood flow.
Viagra isn’t a performance enhancer; it only helps men with ED achieve erections. It’s important to note that sexual stimulation is still required for Viagra to be effective.
While primarily used for ED, Viagra also treats pulmonary arterial hypertension (PAH), a condition involving high blood pressure in the arteries leading to the lungs. In this context, it improves blood flow to the lungs, easing breathing difficulties.

| Pulmonary Arterial Hypertension (PAH) | Improves blood flow to the lungs, reducing strain on the heart and improving breathing. |
Consult your doctor before using Viagra. They can assess your health, determine if Viagra is suitable, and discuss potential side effects, such as headache, flushing, and nasal congestion. Your physician will help you determine the appropriate dosage and address any concerns.
