Sildenafil citrate is the medication that is most commonly used to treat erectile dysfunction (ED) in men. However, there are some other medications that are also used to treat ED, such as the following:

The most commonly prescribed ED medications include Sildenafil citrate (generic name: Viagra), which is a PDE5 inhibitor. Sildenafil is a PDE5 inhibitor that works by blocking the enzyme that breaks down cGMP, which helps relax the smooth muscle in the penis. This allows the blood vessels in the penis to widen, resulting in improved blood flow and an erection.

Sildenafil citrate is usually taken as a single dose before sexual activity. However, it’s important to take it at least 30 minutes before sexual activity, and you should be sure to finish the entire dose. This can help prevent the effects of the drug from affecting your blood pressure and heart rate. If you’re unsure about how to take Sildenafil citrate, consult your doctor about the correct dosage and precautions.
