Vilitra is a medication used for the treatment of erectile dysfunction (ED) in men. It contains vardenafil as its active ingredient, which is a phosphodiesterase type 5 (PDE5) inhibitor. Vardenafil, like other PDE5 inhibitors, helps improve blood flow to the penis, facilitating an erection when there is sexual stimulation.
Here's how Vilitra works:
Active Ingredient - Vardenafil: Vilitra's active ingredient, vardenafil, specifically targets the PDE5 enzyme. PDE5 is responsible for breaking down cyclic guanosine monophosphate (cGMP), a chemical that promotes smooth muscle relaxation and vasodilation in the penile blood vessels.
Increased cGMP Levels: When a man is sexually aroused, nitric oxide is released in the penile tissues, leading to the production of cGMP. Vardenafil inhibits PDE5, allowing cGMP levels to increase. Elevated cGMP levels lead to the relaxation of smooth muscles in the penile blood vessels, allowing increased blood flow to the penis.
Enhanced Blood Flow to the Penis: The increased blood flow to the erectile tissues of the penis results in an improved ability to achieve and maintain an erection during sexual stimulation.
On-Demand Use: Vilitra is typically taken 25 to 60 minutes before anticipated sexual activity. It is effective when there is sexual arousal, as it enhances the natural physiological response to sexual stimuli.
Duration of Action: Vardenafil has a duration of action of around 4 to 5 hours. This means that the medication remains effective for a period of time after ingestion, allowing for a window of opportunity for sexual activity.  |
