Sildenafil is primarily used to treat erectile dysfunction (ED) in men. It helps achieve and maintain an erection by increasing blood flow to the penis. It is also used under the brand name Revatio to treat pulmonary arterial hypertension (PAH), a condition of high blood pressure in the lungs.
Sildenafil is a phosphodiesterase type 5 (PDE5) inhibitor, which works by relaxing the blood vessels in the penis and lungs. This relaxation allows for increased blood flow, which helps in achieving an erection or reducing blood pressure in the lungs.
For erectile dysfunction, Sildenafil is taken orally, usually 30 minutes to an hour before sexual activity. It can be taken with or without food, but a high-fat meal might delay its effect. For pulmonary hypertension, it is taken in a lower dose, usually three times a day.
The effects of Sildenafil typically last for up to 4 hours. However, this does not mean you will have an erection for 4 hours; it means you may achieve an erection within that time window when sexually stimulated.
Sildenafil typically begins to work within 30 to 60 minutes after ingestion, but it may take up to 2 hours to reach full effect, especially if taken with a heavy meal.
