What It Is and How It Works

Sildenafil citrate is a phosphodiesterase type 5 (PDE5) inhibitor. It works by relaxing the muscles found in the walls of blood vessels and increases blood flow to particular areas of the body, most notably the penis. When used for erectile dysfunction, sildenafil helps achieve an erection by enhancing the effects of nitric oxide, a natural chemical your body produces that relaxes muscles and widens blood vessels.

In the context of pulmonary arterial hypertension, sildenafil works by relaxing blood vessels in the lungs, which results in lowered pulmonary blood pressure and improved exercise capacity.

Indications / Uses

The primary approved use of sildenafil citrate is for the management of erectile dysfunction. It helps men with ED achieve and maintain an erection sufficient for sexual intercourse. Additionally, it is approved for treating pulmonary arterial hypertension in adults to improve their ability to exercise and delay any worsening of their condition.

Off-label uses exist but should only be considered under the supervision of a healthcare professional.

Dosage Forms and Typical Dosing Considerations

Sildenafil citrate is commonly available in tablet form with varying strengths such as 25 mg, 50 mg, and 100 mg. The typical starting dose for erectile dysfunction is 50 mg taken approximately one hour before sexual activity. However, dosing may vary based on individual health status, response, and side effects and should be followed as prescribed by a healthcare provider.

In paediatric and special populations like those with liver or kidney impairment, dosing needs careful adjustment and professional supervision.

How to Take It Correctly Step-by-Step

To take sildenafil citrate safely, follow these general steps:
