Sildenafil citrate is the active ingredient in Viagra and other medications used to treat erectile dysfunction (ED). It works by increasing blood flow to the penis, facilitating an erection. This happens by inhibiting an enzyme called phosphodiesterase-5 (PDE5).
How Sildenafil Citrate Works
PDE5 breaks down a chemical called cGMP, crucial for achieving and maintaining an erection. By blocking PDE5, sildenafil allows cGMP levels to remain high, resulting in improved blood flow and easier erection. This mechanism requires sexual stimulation to initiate the process; sildenafil doesn’t create an erection independently.
Important Considerations
Dosage: Always follow your doctor’s prescribed dosage. Incorrect usage can lead to adverse effects. The recommended starting dose is usually 50mg. Side Effects: Common side effects include headache, flushing, nasal congestion, and visual disturbances. Severe side effects are rare but require immediate medical attention. Interactions: Sildenafil can interact with certain medications, especially nitrates. Inform your doctor about all medications you are currently taking. Contraindications: Individuals with certain heart conditions, low blood pressure, or severe liver/kidney problems should avoid using sildenafil. Consult a doctor before using sildenafil.
Sildenafil and Chewable Tablets
Chewable tablets offer faster absorption compared to regular tablets, potentially leading to a quicker onset of action. However, this doesn’t necessarily translate to a longer duration of effect.
