Viagra, or sildenafil citrate, primarily enhances blood flow to the penis, facilitating erections. This occurs by inhibiting an enzyme called phosphodiesterase-5 (PDE5), leading to increased levels of cGMP, a molecule crucial for penile erection. The result is improved erectile function, allowing for stronger and more sustained erections.
However, remember Viagra isn’t a magic bullet. Its efficacy varies depending on individual factors such as overall health, the underlying cause of erectile dysfunction, and even concurrent medication. Optimal results often require a prescription and a discussion with a healthcare professional to rule out any contraindications or potential interactions with other drugs.
Common side effects include headaches, flushing, nasal congestion, and visual disturbances. These are usually mild and temporary. Serious side effects are rare but include vision loss and prolonged painful erections (priapism). Seek immediate medical attention if you experience such symptoms. Always follow your doctor’s instructions regarding dosage and frequency to minimize potential risks and maximize benefits.
