Megalis is an anti-impotent drug that works to treat erectile dysfunction. It is a generic version of Cialis. Tadalafil is the active ingredient in this pill and acts to enhance blood flow to the male organ, which helps to collect the blood in the penile head. This anti-impotent drug works to dilate blood vessels and relax smooth muscles and helps a man to attain an erection when a man is sexually aroused. This drug fails to work if a man lacks sexual desire. Megalis is proven to be effective in improving erectile function in men. It works efficiently irrespective of the severity of erectile dysfunction and the age of a man. This medicine is suitable only for adult men.

The Megalis contains tadalafil, which is a potent PDE5 inhibitor drug that helps to palliate erectile dysfunction. This medicine can act on the root cause of erectile dysfunction. It works to inhibit this enzyme at a cellular level. This enzyme causes a contraction of arteries, which blocks the blood flow. It helps to prevent cyclic Guanosine Monophosphate (cGMP). In short, this drug stops the production of this enzyme called phosphodiesterase-5 (PDE5) temporarily. After this reaction, the body makes nitric oxide in a higher amount, which helps in improving blood flow in the whole body, including to the penile organ. This reaction helps a man to attain an erection when a man is sexually stimulated. Megalis effect lasts up to 36 hours.

Average Rating :

After my major heart surgery, I was dealing with feeble erections. I came to know about the Megalis pill, and I started its dosage after asking my physician. Finally, my love life is normal like before.
