Vilitra is a medication that contains vardenafil hydrochloride as its active ingredient. It belongs to a class of drugs known as phosphodiesterase type 5 (PDE-5) inhibitors, which are primarily used to treat erectile dysfunction (ED) in men. Vilitra pill works by relaxing the smooth muscles in the blood vessels of the penis, allowing for increased blood flow when a man is sexually aroused. This helps to achieve and maintain an erection suitable for sexual activity. Vilitra is typically taken orally, with water, about 25 to 60 minutes before sexual activity. It should be taken as directed by a healthcare provider or as indicated on the medication packaging. It should be noted that sexual stimulation is necessary for the medication to work; it does not cause an erection without arousal.
