Viagra, or sildenafil citrate, primarily treats erectile dysfunction (ED). It works by increasing blood flow to the penis, enabling a firmer erection suitable for sexual intercourse. This effect results from the drug’s inhibition of an enzyme called phosphodiesterase-5 (PDE5).
Who Can Use Viagra?
Men diagnosed with ED, typically defined as consistent difficulty achieving or maintaining an erection sufficient for satisfactory sexual activity, are candidates. However, Viagra isn’t suitable for everyone. Consult your doctor; pre-existing conditions like heart problems, low blood pressure, or certain eye diseases may preclude its use. Also, those taking nitrates or specific other medications should avoid Viagra due to potential interactions. Your physician will assess your suitability and help determine the correct dosage.
Beyond Erectile Dysfunction: Other Uses
While primarily known for ED treatment, research suggests potential uses in treating pulmonary arterial hypertension (PAH), a type of high blood pressure affecting the arteries in the lungs. It’s also being studied for its possible role in other conditions, though these applications remain under investigation.
