Viagra, or sildenafil citrate, primarily treats erectile dysfunction (ED), a condition affecting a man’s ability to achieve or maintain an erection firm enough for satisfactory sexual intercourse. It works by increasing blood flow to the penis.
How Viagra Works
Viagra inhibits an enzyme called phosphodiesterase-5 (PDE5). This allows increased levels of cyclic GMP, a chemical that relaxes muscles in the penis, facilitating blood flow. This mechanism is crucial for achieving and sustaining an erection. The effects usually begin within 30 to 60 minutes of ingestion and can last for up to four hours.
Beyond Erectile Dysfunction
While primarily used for ED, Viagra has shown promise in treating pulmonary arterial hypertension (PAH), a condition causing high blood pressure in the arteries leading to the lungs. This application uses a lower dosage than that for ED treatment. Consult your doctor to discuss if this is an appropriate treatment option.
Important Considerations
Dosage: Always follow your doctor’s prescribed dosage. Incorrect dosage can lead to side effects or ineffectiveness. Side Effects: Common side effects include headache, flushing, nasal congestion, and visual disturbances. Severe side effects are rare but require immediate medical attention. Interactions: Viagra can interact with certain medications, particularly nitrates. Always inform your doctor about all medications you are currently taking. Contraindications: Viagra is not suitable for everyone. Individuals with heart conditions, low blood pressure, or certain eye conditions should exercise caution and consult with their physician.
