Understanding What Sildenafil Is
Sildenafil, commonly known by its brand name Viagra, is a medication primarily used to treat erectile dysfunction (ED) and pulmonary arterial hypertension (PAH). Developed by Pfizer, it has become one of the most prescribed drugs since its approval by the FDA in 1998.
Mechanism of Action
Sildenafil works by inhibiting the phosphodiesterase type 5 (PDE5) enzyme, which results in the dilation of blood vessels. This action increases blood flow to specific areas of the body, notably the penis, facilitating an erection. For PAH patients, this mechanism helps relax blood vessels in the lungs, reducing blood pressure and enhancing exercise capacity.
Indications for Use
- Erectile Dysfunction (ED): Helps achieve and maintain an erection sufficient for sexual intercourse.
- Pulmonary Arterial Hypertension (PAH): Improves exercise ability and delays clinical worsening.
Dosage and Administration
The typical starting dose for erectile dysfunction is 50 mg, taken as needed, approximately one hour before sexual activity. For pulmonary arterial hypertension, the standard dose is 20 mg three times daily. However, dosage may vary based on individual health conditions and response to treatment. Always consult your healthcare provider for personalized advice.
Potential Side Effects
Like all medications, Sildenafil may cause side effects. Common adverse effects include headaches, flushing, indigestion, nasal congestion, and dizziness. Serious, but rare effects can involve vision changes, sudden hearing loss, or an erection lasting more than four hours, which requires immediate medical attention.
Insights from Healthcare Experts
“Sildenafil has transformed the treatment landscape for erectile dysfunction and pulmonary hypertension,” says Dr. Emily Thorne, a board-certified urologist. “It’s crucial for patients to understand the potential effects and to follow their doctor’s recommendations closely.”
