How Does Megalis 20 mg Work?

Tadalafil is working as a PDE-5 inhibitor. PDE-5 enzyme is responsible to return the penis to its normal state after sexual intercourse. The tablet restricts the action of the PDE-5 enzyme, which increases the erection time to roughly 4-6 hours.

In normal circumstances when a man is stimulated, the blood circulation is increased in the body, which increases the flow of the blood in the penis causing an erection. Males that are suffering from ED, can face problems in achieving an erection because the muscles around the blood vessels in the penis are contracted. The Megalis 20 mg helps to relax these muscles and improve the flow of the blood through arteries in the penis causing an erection. Before you intend to take Megalis 20 mg or other ED medicine, it is recommended to consult a doctor because it may be useless or you can experience severe side effects.
