Bosentan is an endothelin receptor antagonist primarily used to treat pulmonary arterial hypertension (PAH). It works by blocking the action of endothelin, a substance that constricts blood vessels, thereby relaxing the blood vessels and improving blood flow to the lungs. This medication helps enhance exercise capacity and improve quality of life in patients with PAH. Common side effects may include headaches and swelling, but these typically resolve over time. In simple terms, Bosentan helps lower blood pressure in the lungs and improves overall heart function.
Bosentan selectively antagonizes endothelin-1 receptors (ETA and ETB), leading to vasodilation and reduced pulmonary vascular resistance.
