Vilitra 60 mg is a medication used for the treatment of erectile dysfunction (ED) in men. It contains the active ingredient Vardenafil, which is a phosphodiesterase type 5 (PDE5) inhibitor. Vardenafil works by increasing blood flow to the penis during sexual stimulation, facilitating the ability to achieve and maintain an erection. Vardenafil inhibits the action of PDE5, an enzyme that breaks down cyclic guanosine monophosphate (cGMP) in the smooth muscle cells of the penis. Increased levels of cGMP result in smooth muscle relaxation, leading to improved blood flow and the facilitation of an erection. Duration of Action: The duration of action of Vilitra 60 mg is typically around 4 to 6 hours. Sexual stimulation is necessary for the medication to be effective.
