Cialis is the trade name of Tadalafil, a pill taken orally to treat male erectile dysfunction (ED). Cialis was developed by ICOS. It was later brought to the world wide market by Lilly ICOS, LLC, the joint venture of ICOS Corporation and Eli Lilly and Company. Eli Lilly and Company later bought ICOS, fired most of the employes and brought Cialis in completely under Eli Lilly and Company ownership. Cialis is also sold under the name Adcirca as a drug for treating of pulmonary arterial hypertension. It is also approved to be used against benign prostatic hyperplasia. Cialies are sold in 5 mg, 10 mg, and 20 mg doses. Tadalafil is sold under the name Tadacip in India by the Indian Pharmaceutical company Cipla and if you buy Tadalafil online you will sometimes recieve this brand instead of Cialis as tadacip is generally cheaper to buy.

Cialis was approved by the FDA to be sold as an aid for Erectile dysfuntion in the US on November 21, 2003. At this time Viagra and Levitra was allready on the market. Cialis quickly gained the name “The Weekend Pill” due to the fact that the effect last for 36 hours. When used for Erectile dysfuntion Cialis is a drug that can be used as needed or to avoid the hassle of planning for sexual activities it can be taken in a smaller dosage daily.. When used against pulmonary arterial hypertension it is supposed to be taken daily. Cialis was approved to be used for treating pulmonary arterial hypertension in 2009 and during late 2011 it was approved to treat benign prostatic hyperplasia.

Cialis is a PDE5 inhibitor that improve the males ability to get an erection as a result of direct sexual stimulation. It is important to understand that cialis will not cause erections without sexual stimulation. The two competitors Viagra and Levitra are also PDE5 inhibitors but Cialis (tadalafil) has a much longer half-life and can therefor be taken longer before sexual activity. The 17.50 hours half-life time, compared to 4.0–5.0 hours for viagra and levitra is what has earned it the popular name “the weekend pill”. Cialis is unlike the two competitors the only drug that is approved to be used daily treating erectile dysfunction. When used daily a very small dosage of 2.5 mg and 5 mg is recommended. When used as a one time drug up to 20mg can be used but the dosage should be set for each patient individually and it is therefore a good idea to talk to a doctor before starting to use Cialis. About 8 million men use cialis.
