Viagra, or sildenafil citrate, treats erectile dysfunction (ED) by increasing blood flow to the penis. This allows for firmer, easier-to-achieve erections.
How Viagra Works
Viagra inhibits an enzyme called phosphodiesterase-5 (PDE5). This enzyme usually breaks down a chemical called cyclic GMP, which is crucial for achieving an erection. By blocking PDE5, Viagra allows cyclic GMP to remain active longer, leading to improved blood flow.
Conditions Treated
While primarily used for ED, Viagra can also help treat pulmonary arterial hypertension (PAH), a condition causing high blood pressure in the arteries leading to the lungs. It improves blood flow in this context as well. Always consult a doctor before using Viagra for any condition.
Important Considerations
Viagra is a prescription medication. Side effects can include headaches, flushing, nasal congestion, and visual disturbances. It’s not suitable for everyone, particularly individuals with certain heart conditions, low blood pressure, or those taking specific medications like nitrates. A doctor will assess your suitability and potential risks.
