Sildenafil citrate is the active ingredient in Viagra and other medications used to treat erectile dysfunction (ED). It’s a phosphodiesterase-5 (PDE5) inhibitor. This means it works by increasing blood flow to the penis, helping men achieve and maintain an erection.
How Sildenafil Citrate Works
Sildenafil citrate blocks the action of PDE5, an enzyme that breaks down cyclic GMP. Increased cyclic GMP levels relax the muscles in the blood vessels of the penis, allowing more blood to flow in.
- This increased blood flow is crucial for achieving an erection. The effect only occurs in the presence of sexual stimulation.
Important Considerations
Sildenafil citrate is not a performance enhancer; it facilitates natural responses. Consult a doctor before use, especially if you have heart problems, high blood pressure, or take other medications. Common side effects include headache, flushing, and nasal congestion. Discuss any concerns with your physician. Dosage varies depending on individual needs and should be determined by a healthcare professional.
Remember, always consult a doctor or pharmacist before starting any new medication.
