About Tadalafil
Tadalafil is a medication for treatment of erectile dysfunction or ED that is taken in pill form. Tadalafil was originally developed by a biotechnology corporation called ICOS. It was once again manufactured in a joint venture between the ICOS Corporation and Eli Lilly and Company, a major pharmaceutical business, marketed under the brand name Cialis. Sold in tablet form and shaped like an almond, tadalafil is available in 5 mg, 10 mg, and 20 mg doses.
Tadalafil (Generic Cialis) acts faster than Viagra and lasts for up to 36 hours.

Tadalafil, or Cialis, the name it was approved under by the FDA in 2003, was the third in a line of erectile dysfunction medications and was preceded to market by sildenafil [Viagra] that was first, and vardenafil [Levitra] that hit the market second. Tadalafil earned its spurs on the basis of fact that it lasted for 36 hours as opposed to 4 – 5 hours for its predecessors. This is why tadalafil became known as “TheWeekend Pill”; and like the others is usually prescribed as needed. Of the three ED medications, tadalafil alone is also offered as a once daily drug therapy.
In addition to the treatment of ED, tadalafil is also being considered as a medication alternative for pulmonary arterial hypertension as a competitor to sildenafil. Pharmaceutical company Eli Lilly put tadalafil’s American rights up for sale for pulmonary arterial hypertension and in late 2008; they were purchased by United Therapeutics for approximately $150 million.
History of Tadalafil
No history of tadalafil would be complete without discussing its predecessor Viagra [or sildenafil]. It was developed, manufactured and marketed by Pfizer Pharmaceuticals as a treatment for ED after FDA approval in 1998. It became a commercial success and an advertising spectacle but sales were beyond one billion dollars. Next, the FDA approved Levitra [or vardenafil] in mid 2003, which was followed up in late 2003 by Cialis [or Tadalafil].
