This compound works by relaxing the blood vessels in the penis, allowing increased blood flow and facilitating an erection when sexually aroused.
Sildenafil citrate was first introduced by Pfizer in 1998 as an effective treatment for ED. It was approved by the FDA in 2003 for the treatment of pulmonary arterial hypertension (PAH).
This compound belongs to the class of phosphodiesterase type 5 (PDE5) inhibitors and works by increasing blood flow to the penis during sexual stimulation. It helps men achieve and maintain an erection when sexually aroused.
Sildenafil citrate is effective for the treatment of erectile dysfunction (ED), which is the inability to achieve or maintain an erection sufficient for sexual activity. It has also been found to be effective for the treatment of pulmonary arterial hypertension (PAH), a condition where high blood pressure in the lungs is a significant risk factor for ED.

The medication can also have a vasodilatory effect when sexual stimulation occurs, which helps to improve sexual performance and satisfaction.
The recommended dosage of Sildenafil citrate is one tablet taken orally, with or without food, approximately 30 minutes to an hour before engaging in sexual activity. The recommended dosage is based on the patient’s age, health condition, and response to therapy.
Common side effects include headache, flushing, indigestion, nasal congestion, dizziness, and upset stomach. More severe side effects, though rarer, may include prolonged erections, vision changes, and vision loss. Rare but more serious side effects, though less common, include severe chest pain, high blood pressure, and priapism (a prolonged and painful erection).

Sildenafil citrate can also interact with certain medications, including nitrates, alpha-blockers, and blood pressure medications. Nitrates, for example, can lower blood pressure and cause a drop in blood pressure when used in combination with Sildenafil citrate. Alpha-blockers and blood pressure medications can also increase blood pressure and cause a drop in blood pressure when used with Sildenafil citrate. Therefore, it is important to inform your healthcare provider about all medications and supplements you are taking.
Store Sildenafil citrate at room temperature, away from moisture, heat, and direct light. Do not store in a bathroom. Keep all medications away from children and pets.
