Vardenafil, the active ingredient in Vilitra 60, is a phosphodiesterase type 5 (PDE5) inhibitor. It works by increasing blood flow to the penis during sexual stimulation, which helps men achieve and maintain erections suitable for sexual activity. Due to its relatively long duration of action, Vilitra 60 allows for greater spontaneity in sexual activities. Men can engage in sexual intercourse without strict timing constraints, leading to a more natural and enjoyable experience.
