Sildenafil citrate is the key component responsible for Viagra’s effects. It’s a phosphodiesterase-5 (PDE5) inhibitor. This means it works by blocking the action of an enzyme that breaks down cyclic GMP, a molecule crucial for blood vessel dilation in the penis.
Increased cyclic GMP leads to increased blood flow. This mechanism facilitates penile erection in response to sexual stimulation. It’s important to note that sildenafil citrate does not cause erections on its own; sexual stimulation is required.
Viagra comes in various dosages, typically ranging from 25mg to 100mg. Your doctor will determine the appropriate dosage based on your individual health and medical history. Always follow their prescribed dosage instructions carefully.
Common side effects can include headache, flushing, nasal congestion, and visual disturbances. These are usually mild and temporary. More serious side effects are rare but require immediate medical attention. Consult your doctor about any concerns.
Remember: Sildenafil citrate, the active ingredient in Viagra, is a prescription medication. Always obtain it from a licensed healthcare professional and discuss potential drug interactions or health risks before use. Misuse can be dangerous.
