Viagra, or sildenafil citrate, primarily treats erectile dysfunction (ED). It works by increasing blood flow to the penis, allowing for a firmer erection. This improved blood flow results from the drug’s inhibition of a specific enzyme, PDE5.
How Viagra Works
Viagra doesn’t act as a direct stimulant; it enhances the body’s natural response to sexual stimulation. For Viagra to be effective, sexual stimulation is necessary. The drug is not a performance enhancer in the absence of desire. It’s crucial to understand this distinction.
Beyond ED: Pulmonary Hypertension
Beyond ED, Viagra also treats pulmonary arterial hypertension (PAH). In PAH, blood pressure in the arteries leading to the lungs is abnormally high. Viagra helps dilate these blood vessels, reducing blood pressure and improving blood flow to the lungs. This application requires a prescription and close medical supervision.
Important Note: Viagra has potential side effects, including headache, flushing, and nasal congestion. Consult your doctor before using Viagra or any medication to discuss potential risks and interactions with other medications you may be taking. Self-treating can be dangerous; always seek professional medical advice.
Dosage and Administration
Viagra dosages vary based on individual needs and medical history. Your physician will determine the appropriate dosage. Typically, it’s taken orally, approximately 30-60 minutes before anticipated sexual activity. It’s generally not recommended to take more than one dose per day.
