About
Cialis 20mg is the strongest strength available of this erectile dysfunction medication. The active ingredient in this medication is called Tadalafil 20mg and it operates in a similar way to other erection drugs such as Viagra.
Cialis treats erectile dysfunction by increasing blood flow to the penis and relaxing the relevant muscles. It can also be used to make erections last longer as it inhibits the naturally occurring chemical in the body that allows the blood to leave the penis and makes the erection subside.
