Vilitra 40 is a medication used to treat erectile dysfunction (ED) in men. It contains Vardenafil as the active ingredient, which is a PDE5 inhibitor. This medication helps improve blood flow to the penis, enabling men to achieve and maintain an erection when sexually aroused. Increased levels of cGMP lead to relaxation of the smooth muscles and dilation of blood vessels in the penis, allowing for enhanced blood flow during sexual stimulation. Swallow the tablet whole with a glass of water. It is recommended to take it on an empty stomach or after a light meal. Avoid heavy meals before taking the medication, as it may delay its effects.
