Vilitra is a medication primarily used to treat erectile dysfunction (ED) in men. It contains vardenafil as its active ingredient, which is a phosphodiesterase type 5 (PDE5) inhibitor. Vilitra contains vardenafil, which works by increasing blood flow to the penis during sexual stimulation. This helps men achieve and maintain erections suitable for sexual intercourse. Vardenafil in Vilitra generally starts working within 30 to 60 minutes after ingestion, with its effects lasting for about 4 to 6 hours. Individual response may vary, and factors such as metabolism and dosage can influence the duration of action.
