Tracleer is an endothelin receptor antagonist prescribed to treat pulmonary arterial hypertension (PAH), a condition involving high blood pressure in the blood vessels of the lungs. Tracleer helps to relax the blood vessels in the lungs by blocking a particular hormone, which allows blood to flow more easily and improves a patient's ability to exercise.
Tracleer has been linked to the following serious side effects:
- Birth defects
- Liver damage
- Low red blood cell count (anemia)
- Reduced sperm count
