Sildenafil is a medication used to treat erectile dysfunction (ED) in men. It belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors, which work by relaxing the blood vessels in the penis, increasing blood flow, and allowing for an erection to occur in response to sexual stimulation.

Sildenafil is marketed under the brand name Viagra, and it was approved by the United States Food and Drug Administration (FDA) in 1998. It is also used to treat pulmonary arterial hypertension (PAH), a condition in which the blood pressure in the arteries that supply the lungs is too high.

How Does Sildenafil Work?

Sildenafil works by blocking the action of an enzyme called phosphodiesterase type 5 (PDE5), which is responsible for breaking down a substance called cyclic guanosine monophosphate (cGMP) in the penis. cGMP is a molecule that helps to relax the smooth muscle in the blood vessels in the penis, allowing for increased blood flow and an erection to occur.

When a man is sexually stimulated, the body releases nitric oxide (NO) into the penis, which activates an enzyme called guanylate cyclase. Guanylate cyclase then produces cGMP, which causes the smooth muscle in the blood vessels to relax and increases blood flow to the penis, resulting in an erection.

However, in men with erectile dysfunction, PDE5 breaks down cGMP too quickly, preventing the smooth muscle in the blood vessels from relaxing and reducing blood flow to the penis. Sildenafil works by inhibiting PDE5, which allows cGMP to accumulate, leading to increased blood flow and improved erectile function.

It is important to note that Sildenafil does not work without sexual stimulation. It enhances the body’s natural response to sexual stimulation, but it does not increase sexual desire on its own.

Dosage and Administration of Sildenafil

Sildenafil is available in tablet form, and the recommended dosage varies depending on the individual and the condition being treated.

For erectile dysfunction, the usual starting dose of sildenafil is 50 milligrams (mg), taken one hour before sexual activity. The dose can be adjusted based on the individual’s response and tolerance, up to a maximum dose of 100 mg per day. Sildenafil should not be taken more than once per day.

For pulmonary arterial hypertension, the starting dose is usually 20 mg, taken three times per day, with a maximum dose of 80 mg per day.

Sildenafil should be taken with a full glass of water, and it can be taken with or without food. It is important to avoid eating high-fat meals before taking sildenafil, as this can slow down the absorption of the medication and reduce its effectiveness.

It is important to follow the dosage instructions provided by a healthcare professional and not exceed the recommended dose. Overdose of sildenafil can lead to serious side effects and should be avoided. If a dose is missed, it should be taken as soon as possible, but the next dose should not be taken too soon, according to the prescribed schedule.

Side Effects of Sildenafil

Like all medications, Sildenafil can cause side effects, although not everyone experiences them. Some common side effects of Sildenafil include:

• Headache
• Flushing (warmth, redness, or tingly feeling in the face, neck, or chest)
• Dizziness or lightheadedness
• Nausea or stomach upset
• Nasal congestion
• Changes in vision, such as blurred vision or color changes
• Back pain or muscle pain

These side effects are usually mild and go away on their own. However, if they persist or become severe, a healthcare professional should be consulted.
