How Megalis 20 works?

Like Sildenafil and Vardenafil, Megalis is a selective and a potent Phosphodiesterase type 5 enzyme (PDE5) inhibitor. By inhibiting the enzyme, Megalis increases the amount of cGMP (cyclic Guanosine Monophosphate) inside the penis. This releases nitric oxide and therefore, increases the blood flow inside the penis.  Thus, ultimately it leads to a penile erection during sexual intercourse.
