Need a clear, concise explanation of Viagra’s active compound? It’s sildenafil citrate. This medication directly affects blood flow to the penis, facilitating erections. Understanding its mechanism is key to safe and effective use.
Sildenafil works by inhibiting a specific enzyme, phosphodiesterase-5 (PDE5). This enzyme normally breaks down cGMP, a molecule vital for penile erection. By blocking PDE5, sildenafil allows cGMP levels to rise, leading to increased blood flow and improved erectile function. This process is highly targeted, minimizing side effects in many individuals.
However, remember that sildenafil interacts with certain medications. Always consult a doctor before starting any new medication, including Viagra, especially if you have heart problems, high blood pressure, or are taking nitrates. Your doctor can help determine the appropriate dosage and address any potential concerns to ensure your safety.
