The History Behind Tadalafil’s Approval
The approval of sildenafil in 1998 was the pioneering event for erectile dysfunction treatment with over $1 billion in sales. In 2003, the FDA approved Tadalafil.
ICOS, a biotechnology company originally developed the drug, but it was later redeveloped by Lilly ICOS, LLC, which is a joint venture of the ICOS Corporation and Eli Lilly and company.
It wasn’t until 2009 that Tadalafil was approved in the United States for treating pulmonary arterial hypertension.
What is Tadalafil?
Tadalafil is a phosphodiesterase type 5 inhibitor (PDE5) that increases the flow of blood to the penis and dilates blood vessels in the lungs.
This drug is especially helpful in the treatment of Erectile Dysfunction, benign prostatic hyperplasia (BPH, enlarged prostate), and pulmonary arterial hypertension (PAH, difficulty in the flow of urine, weak stream).
Tadalafil is approved by the FDA for the treatment of erectile dysfunction. In addition, it is also effective in the treatment of lower urinary tract symptoms caused by prostatic hyperplasia.
This drug is also approved by the FDA in enhancing the exercise capability in pulmonary arterial hypertension (PAH) patients.

How does Tadalafil work?
Once it is administered, this drug increases the flow of blood to the penis and relaxes the muscles in the bladder and prostate which helps men in getting and maintaining an erection. The action of Tadalafil on the penis is not automatic. It simply makes it possible for blood to flow to the organ when the man is ready for sex. You need to engage in foreplay to get an erection. The blood will continue to flow for as long as the chemical is in the body.
