Vilitra 20 mg is commonly prescribed to treat a male s*xual dysfunctional condition called impotence, also known as erectile dysfunction (ED). Each tablet of this medicine contains 20 mg of a monohydrochloride salt (HCl) of vardenafil. Classified in the phosphodiesterase 5 inhibitor drug class (PDE-5 inhibitor), it helps to achieve an erection by letting more blood flow into the penis. It can be taken with or without food. Effects usually appear between 30 minutes and 1 hour after consumption. The effects of this drug last for 4 to 5 hours.
Cyclic guanosine monophosphate (cGMP) plays a crucial role in achieving an erection because it increases the vasodilation of the penile muscles, increasing blood flow. However, PDE-5 is an enzyme known to break down cGMP and cause a weak erection. Vardenafil (the active substance in Vilitra) stops the activity of the PDE-5 enzyme by mimicking cGMP. It is structurally so similar to cGMP that the PDE-5 enzyme binds to Vardenafil instead of cGMP. A higher concentration of cGMP in the blood will increase blood circulation in the p*nis and help you get / maintain a firm erection during sexual intercourse.
