Vilitra is a medication primarily used to treat erectile dysfunction (ED) in men. It contains the active ingredient Vardenafil, which is a type of phosphodiesterase type 5 (PDE5) inhibitor. Vardenafil helps to increase blood flow to the penis by inhibiting the enzyme PDE5. This leads to improved erectile function when a man is sexually aroused. It is typically taken orally about 30 minutes to an hour before sexual activity. The effects can last for several hours, though the exact duration may vary from person to person. It's important to use Vilitra under the guidance of a healthcare provider to ensure it's safe and appropriate for your specific situation.
