Cialis (or Tadalafil) was developed by American pharmaceutical company Lilly. It is used to treat erectile dysfunction and belongs to a second generation of PDE5 inhibitors. Studies show that Cialis works very quickly, taking effect in around 15-20 minutes, and has a prolonged effect that can last for up to 36 hours. In a study of 348 cases of mild to severe erectile dysfunction, patients were randomly given 20mg of Cialis or a placebo. Results showed that in comparison to the placebo group, patients who took Cialis experienced improved intercourse success in the 24-36 hours following medication, with many patients achieving successful sexual intercourse twice in 36 hours. Side effect rate and severity were also no different from those of the placebo group. Over 5% of patients in the Cialis group experienced headaches and indigestion. No perceived facial flushing or sight abnormalities following medication. Patients currently taking nitrates, experiencing angina pectoris, suffering from heart disease, patients who have unregulated hypertension or hypotension, or patients who have had a stroke in the past 6 months should not take Cialis. Tadalafil (market name “Cialis” or “Adcirca”) is a kind of PDE5 inhibitor used for the treatment of erectile dysfunction, benign prostatic hypertrophy and pulmonary arterial hypertension. zoloft 50 mg pill -kə, and Tadacip for the treatment of pulmonary arterial hypertension. It initially was developed by the biotechnology company ICOS, and then again developed and marketed worldwide by Lilly ICOS, LLC, the joint venture of ICOS Corporation and Eli Lilly and Company. Food and Drug Administration (FDA) approved Cialis for treating the signs and symptoms of benign prostatic hyperplasia (BPH) as well as a combination of BPH and erectile dysfunction when the conditions coincide. Cialis tablets, in 2.5 mg, 5 mg, 10 mg, and 20 mg doses, are yellow, film-coated, and almond-shaped. The approved dose for pulmonary arterial hypertension is 40 mg (two 20 mg tablets) once per day (OD). On November 21, 2003 the FDA approved tadalafil (as Cialis) for sale in the United States as the third ED prescription drug pill (after sildenafil citrate (Viagra) and vardenafil (Levitra)). Like sildenafil and vardenafil, tadalafil is recommended as an 'as needed' medication. Tadalafil was approved in May 2009 in the United States for the treatment of pulmonary arterial hypertension and is under regulatory review in other regions for this condition. In late November 2008, Eli Lilly sold the exclusive rights to commercialize tadalafil for pulmonary arterial hypertension in the United States to United Therapeutics for an upfront payment of $150 million.

Cialis was developed by Eli Lilly as a treatment for impotence. In this capacity, it is reported that tadalafil functions by inhibiting the formation of cyclic guanosine monophosphate (c GMP)-specific phosphodiesterase type 5 (PDE5). The inhibition of PDE5 presumably lessens impotence by increasing the amount ot c(i MP, resulting in smooth muscle relaxation and increased blood flow. Food and Drug Administration (FDA) approved Cialis for treating the signs and symptoms of benign prostatic hyperplasia (BPH) as well as a combination of BPH and erectile dysfunction (ED) when the conditions coincide. Tadalafil is a PDE5 inhibitor marketed in pill form for treating erectile dysfunction (ED) under the name Cialis, and under the name Adcirca for the treatment of pulmonary arterial hypertension. It initially was developed by the biotechnology company ICOS, and then again developed and marketed world-wide by Lilly ICOS, LLC, the joint venture of ICOS Corporation and Eli Lilly and Company. Cialis tablets, in 2.5 mg, 5 mg, 10 mg, and 20 mg doses, are yellow, film-coated, and almond-shaped. The approved dose for pulmonary arterial hypertension is 40 mg (two 20-mg tablets) once daily. Tadalafil is an orally administered drug used to treat male erectile dysfunction (impotence). It is marketed worldwide under the brand name Cialis. Tadalafil's distinguishing pharmacologic feature is its longer half-life (17.5 hours) compared with Viagra and Levitra (4-5 hours). This longer half-life results in a longer duration of action and is, in part, responsible for the Cialis nickname of the "weekend pill." This longer half-life also is the basis of current investigation for tadalafil's use in pulmonary arterial hypertension as a once-daily therapy.
