Very good catch on this.

Doctors could prescribe this drug already for this very condition in place of other BP medications, I would assume.

From what I could see, pulmonary hypertension, is not something that is treated the same as other causes of high blood pressure, if it is diagnosed. I also get impression this drug is fairly new and they do not know why it works. I wonder how under-diagnosed this disorder is. I think most of the time when someone has high blood pressure, rather than take any steps at all to see what the underlying cause is, they just throw a pill at you. It sure does look like a promising treatment for lung cancer, COPD catch all, and some other serious things. It is something I am going to follow. Need to look into when phase III studies will be started and where. They will probably mess around doing studies for another 5 or 10 years or someone will realize there is not big money to be made and it will fade away.
