Like the brand Levitra, Generic Levitra contains the active ingredient Vardenafil which is the second member of the drug class phosphodiesterase type-5 inhibitors.
Vardenafil in Levitra generic after consumption of the tablet, dissolves in the stomach, gets absorbed in the body and enters the blood stream. After this, it blocks the action of the enzyme PDE-5 which is the main reason behind the occurrence of ED in men. As it inhibits the enzyme PDE-5, the levels of the enzyme nitric oxide and guanylyl cyclase increases in the penile region. This leads to an increase in the phosphodiesterase type-5 specific cyclic guanosine monophosphate (cGMP) which is considered and is a proven dilator or a chemical that widen the blood vessels present underneath the penis of a male. Widening of the penile blood vessels increases the flow of the blood in the penile region. Inhibition of PDE-5 also leads to relaxation of penile muscles which leads enhancement in the inflow of the blood to the penis and less blood moving outside the penis. These mechanisms lead to long-lasting erection which is hard and firm enough for satisfactory sexual intercourse.
