Pulmonary hypertension I have been scouring the scientific literature to see if there is any drug, approved or in development, that can reverse pulmonary hypertension, so that the disease is fixed, not just temporarily helped while the drug is being taken.
I can find none.
There are a bunch of drugs out there that lower pulmonary pressure but as soon as you stop taking them the pulmonary blood pressure goes right back up to where it was before the drug was started.
In the same animal models of pulmonary hypertension, R-107 is different, based on the press release from Claritas last month. It said that R-107 fixes the blood pressure in the lung so that it stays low even after stopping R-107.
As far as I can tell, and I read about 150 articles, everything I could get my hands on through MEDLINE, there is no other drug that has ever been shown to do this. R-107 appears therefore to be a cure, not a temporary fix.
