Vardenafil, the active ingredient in Vilitra 10 mg, works by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which restricts blood flow to the penis. By blocking this enzyme, Vardenafil allows the blood vessels in the penis to relax, leading to improved blood flow and an erection in response to sexual stimulation. This mechanism is similar to other PDE5 inhibitors like Viagra (Sildenafil) and Cialis (Tadalafil), but with some differences in how quickly it takes effect and how long it lasts.
