What is Sildenafil?

Sildenafil, the generic for Viagra, is a prescription medicine used to address male sexual dysfunction known as erectile dysfunction (ED) and pulmonary arterial hypertension. Sildenafil belongs to a group of medications called phosphodiesterase type 5 (PDE5) inhibitors.

How Does Sildenafil Work?

Sildenafil works by improving the body's natural response to sexual stimulation. When a man is sexually aroused, the body releases a chemical known as nitric oxide in the penis.

Sildenafil blocks the activity of an enzyme called PDE5 that normally breaks down the signals triggered by nitric oxide. This allows the smooth muscles of the penis to relax. This improves blood flow to the penis and as the erectile tissue fills with proper blood, it compresses the veins that normally drain blood away. This process helps to get and sustain a firm penile erection.

For PAH, sildenafil (Revatio) works by relaxing or widening the arteries. When the arteries are widened, it makes it easier for your heart to pump blood through the lungs, lowering blood pressure in the lungs.

What is Sildenafil Used For?

Sildenafil is used to address the symptoms of erectile dysfunction (ED) in adult men and pulmonary arterial hypertension (PAH) in children and adults, depending on the formulation or brand [1].

How Long Does Sildenafil Take to Work and How Long Does It Last?

It usually takes between 30 to 60 minutes for Sildenafil to show its effects for most people. It reaches its peak effect after around an hour. Everyone responds to medication slightly differently. Some individuals may take a little longer to feel the effects of Sildenafil, while others may feel them within just 12 minutes of taking it. This difference is completely normal and depends on how quickly your body absorbs the medicine. It works best on an empty stomach therefore avoid fatty meals before taking it.

Sildenafil usually lasts between 4 to 6 hours before its effects fully wear off. This does not mean a man should have a continuous erection if used for ED.

Sildenafil is available in the dosage strengths of 20 mg, 25 mg, 50 mg and 100 mg depending on the formulation and the condition being addressed.
