Treatment of erectile dysfunction (ED) in adult men.
Treatment of pulmonary arterial hypertension (PAH) in specific cases (different dosages and formulations may be used).
Pah 20mg Tab (Sildenafil) inhibits phosphodiesterase-5 (PDE5), an enzyme that breaks down cyclic guanosine monophosphate (cGMP). Increased cGMP levels relax blood vessels in the penis, leading to improved blood flow and facilitating erection in men with ED. In PAH, it improves blood flow in the pulmonary arteries, reducing blood pressure.

Dosage for ED is typically 50mg taken as needed, approximately 1 hour before sexual activity. Dosage may be adjusted to 25mg or 100mg depending on individual response and tolerance.
