When Do Serious Side Effects Require Bosentan Cessation?
Understanding Bosentan: A Pulmonary Arterial Hypertension Treatment
Bosentan is a medication used to treat pulmonary arterial hypertension (PAH), a condition characterized by high blood pressure in the arteries of the lungs. PAH can lead to shortness of breath, fatigue, and other symptoms that can significantly impact a person's quality of life. Bosentan works by relaxing the blood vessels in the lungs, making it easier for blood to flow through them.
How Bosentan Works
Bosentan belongs to a class of medications called endothelin receptor antagonists. It blocks the action of endothelin, a substance that causes blood vessels to constrict. By blocking endothelin, bosentan helps to dilate the blood vessels in the lungs, reducing blood pressure and improving blood flow.
