The main purpose of vilitra is to treat male erectile dysfunction. A guy with erectile dysfunction is unable to get or keep an erection strong enough for sexual activity. When sexually aroused, it helps the user develop and maintain an erection by increasing blood flow to the penis. Vardenafil, the active component of Vilitra 60, functions by preventing the PDE-5 enzyme from functioning. Cyclic guanosine monophosphate (cGMP), which is essential for controlling blood flow to the penis, is broken down by this enzyme. PDE-5 inhibition raises cGMP levels, which relaxes the smooth muscles in the penis and increases blood flow to the erectile tissues.
