Vilitra is a medication used for the treatment of erectile dysfunction (ED) in men. It contains the active ingredient vardenafil, which belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. Vardenafil works by inhibiting the action of the PDE5 enzyme, which is responsible for the degradation of a chemical called cyclic guanosine monophosphate (cGMP) in the penis. During sexual stimulation, nitric oxide is released in the erectile tissue of the penis, which activates an enzyme called guanylate cyclase. This enzyme increases the production of cGMP, which relaxes the smooth muscles in the penile blood vessels, allowing increased blood flow into the penis. This increased blood flow leads to an erection. PDE5 inhibitors like vardenafil prevent the breakdown of cGMP by blocking the action of the PDE5 enzyme. By doing so, vardenafil helps to maintain higher levels of cGMP in the penis, promoting prolonged and improved blood flow, which facilitates an erection. It's important to note that vilitra vardenafil requires sexual stimulation to work effectively. It does not automatically cause an erection; it enhances the natural erectile response when sexual arousal is present. The medication typically starts working within 30 to 60 minutes after ingestion and can last for up to 4 to 5 hours, providing a window of opportunity for sexual activity. It is important to follow the instructions of your healthcare provider and not exceed the recommended dosage.
