Cialis is a new prescription drug that cures erectile dysfunction. Approved by the FDA in 2003 this has become the third medicine officially dealing with ED problems. Due to its long lasting effect up to 36 hours, Cialis became known as the “weekend pill”.
It was discovered in 1993 by the ICOS Company under the codename IC351. A year later the company was granted patent and clinical studies started right away. These were divided in three phases which lasted over 5 year. In 1998 Icos and Eli Lilly and Co. joined forces to market the drug for the treatment of sexual dysfunction and two years later the new company filed a new drug application with the FDA changing the name of IC351 into Cialis. After three more years of successful testing, Cialis was approved and began to be commercialized in all drug stores.
