Double Blind, Randomized Trial of Bosentan for Sarcoidosis Associated Pulmonary Hypertension
Completed · Phase 2/Phase 3 · Has a placebo group
Conditions studied: Sarcoidosis, Pulmonary Arterial Hypertension
In brief
Patients with advanced sarcoidosis often develop pulmonary hypertension. Pulmonary hypertension is a condition where the right side of the heart has to push the blood though the lungs at a higher pressure than normal. Since this pressure is higher, it is harder for the heart to pump the blood through the lungs to the left side of the body. If the blood can not get through the lungs, it can not get pumped through the rest of the body. This leads to weakness and shortness of breath. This type of hypertension does not usually respond to regular blood pressure medicines. The purpose of this study is to determine if bosentan (Tracleer) will help sarcoidosis associated pulmonary hypertension.
