Quick Facts

• Sildenafil citrate is used primarily to treat erectile dysfunction.
• Works by increasing blood flow to the penis, aiding erection during sexual arousal.
• Common forms include tablets taken orally.
• Onset of action is typically 30-60 minutes, lasting up to four hours.
• Must not be taken with nitrates due to severe blood pressure interactions.
• Common side effects include headache, flushing, and dizziness.
• Discuss all other medications with a healthcare provider to avoid interactions.
• Not recommended for individuals with severe heart or liver conditions without doctor approval.

What It Is and How It Works

Sildenafil citrate is a phosphodiesterase type 5 (PDE5) inhibitor. By blocking PDE5, it prevents the destruction of cGMP, a molecule that helps relax blood vessels in the penis. This action allows blood flow into the penile tissues when a man is sexually aroused, facilitating an erection.

The technical action involves the release of nitric oxide in the corpus cavernosum during sexual arousal, which activates the enzyme guanylate cyclase. This sequence results in increased levels of cGMP, producing smooth muscle relaxation and inflow of blood to the penis.

Indications / Uses

The primary indication for sildenafil citrate is the treatment of erectile dysfunction. It is effective for many men, including those with ED resulting from psychological or physical causes. Off-label uses include treatment for pulmonary arterial hypertension, although this usually involves other dosages and formulations.

Persons experiencing ED and interested in using sildenafil should discuss it with a healthcare provider to determine if it\’s suitable for their condition.

Dosage Forms and Typical Dosing Considerations

Sildenafil citrate is typically available in tablet form in dosages such as 25 mg, 50 mg, 100 mg, and sometimes 200 mg for severe cases of erectile dysfunction. Dosage is influenced by the user’s age, kidney function, liver function, and other present health conditions.

It is essential to follow a healthcare provider’s guidance on taking sildenafil citrate, as misuse or overuse can lead to serious health risks.
