What is Cialis 20mg Tablet

Cialis 20 mg tablet is a medicine that men take for the treatment of Erectile Dysfunction. 

Tadalafil is the active ingredient present in Cialis 20 mg.

Tadalafil in 20 mg Cialis regulates the PDE5 enzyme in the penis that helps men in getting and keeping a firm erection.

Cialis 20mg is a prescription-only medication that can be purchased from any pharmacy or online pharmacy with a valid prescription.

Uses of Cialis 20mg

Cialis 20mg containing Tadalafil primarily treats a male sexual disorder, Erectile Dysfunction (ED). 

Erectile Dysfunction or male impotence happens when a man cannot attain and maintain an erection. 

ED can be caused by various physical and psychological factors affecting the blood flow towards the penile region.

How does the Cialis 20mg tablet work

Tadalafil (PDE-5 inhibitor) is the main ingredient in Cialis 20mg used for increasing the blood flow to the penis by relaxing the muscles in penile blood vessels.

Tadalafil belongs to the PDE5 Inhibitor class of medicines. 

PDE5 enzyme is responsible for breaking down cyclic Guanosine Monophosphate (cGMP).

Cialis works by inhibiting PDE5 enzymes, which results in raised cGMP levels. 

Increased levels of cGMP relax the blood vessels in the penile region. 

Relaxation of the blood vessels leads to increased blood flow in the penis. 

Thus, helping men in getting and maintaining a firm erection for a better sexual experience. 

However, sexual stimulation is necessary for a man to get and keep an erection.
