What is Sildenafil? A Potent Phosphodiesterase-5 Inhibitor Explained
- Drug Class: Phosphodiesterase type 5 (PDE5) inhibitor
- Common Brands: Viagra®, Revatio®
- Main Uses: Erectile dysfunction, pulmonary arterial hypertension
- First Approved: 1998 (FDA.gov)
Sildenafil is a well-known medication designed primarily for the management of erectile dysfunction (ED) in men. The story doesn’t end there, however—it’s also prescribed under the name Revatio® for pulmonary arterial hypertension (PAH), a rare and serious heart-lung condition. The mechanism of action is rooted in a simple yet powerful principle: enhancing blood flow where your body needs it most.
How Does Sildenafil Work? The Science Behind the Blue Pill
Sildenafil works by selectively inhibiting phosphodiesterase type 5 (PDE5), an enzyme responsible for breaking down cyclic GMP. When PDE5 is blocked, levels of cGMP increase, resulting in relaxation of smooth muscle and improved blood flow. Here’s what that means for you:
- Enhanced Blood Flow: To the penis (improving erections) or lungs (reducing blood pressure in PAH).
- Faster and Fuller Erections: But only with sexual stimulation—no awkward surprises!
- Duration: Effects noticeable within 30-60 min, lasting 4-6 hours (source: NHS.uk).

| Duration | 4-6 hours | up to 36 hours | 4-5 hours |

Indications: Why is Sildenafil Prescribed?
- Erectile Dysfunction (ED): Most commonly prescribed, affecting 1 in 10 men at some point (Cleveland Clinic).
- Pulmonary Arterial Hypertension (PAH): Under the brand Revatio®—improves exercise capacity and delays disease progression.
- Off-label Uses: Raynaud’s phenomenon, altitude sickness—always consult a healthcare provider.
Sildenafil for Erectile Dysfunction: How to Use Safely
- Take 30-60 Minutes Before Activity: Swallow tablet with water, with or without food.
- Recommended Starting Dose: 50 mg, adjusted between 25-100 mg depending on response and tolerability.
- Do Not Exceed Once Per 24 Hours: To avoid adverse events.
- Sexual Stimulation Is Required: Sildenafil does not cause erections in the absence of stimulation.

PAH Treatment with Sildenafil: Special Guidelines
- Often prescribed at a lower dose (20 mg, three times daily).

- Not interchangeable with ED formulations without consulting a prescriber.
