About Cialis.

Cialis is an oral therapy indicated for treatment of male’s impotence marketed by Eli Lilly and Company and available on the pharmaceutical market since November 2003 when it was approved by FDA after several clinical studies which proved efficacy and safety of the medication.
Cialis is produced in a dosage form of tablets, in 5 mg, 10 mg, and 20 mg doses. The pills are yellow, film-coated, and almond-shaped.
