Bosentan 62.5mg Tablet is an oral prescription medication designed to treat pulmonary arterial hypertension (PAH), a serious condition marked by high blood pressure in the arteries of the lungs. PAH can cause shortness of breath, fatigue, chest pain, and even right-sided heart failure if not properly managed. Bosentan belongs to the endothelin receptor antagonist (ERA) class of drugs, which works by blocking endothelin—a naturally occurring substance that causes blood vessels to constrict—thereby lowering pulmonary vascular resistance and improving blood circulation in the lungs.

Bosentan 62.5mg Tablet is often used as an initial therapy or maintenance dose for adults with PAH, including idiopathic, heritable, or connective tissue disease–associated forms. By reducing pulmonary artery pressure, this medication helps patients enhance exercise tolerance, relieve symptoms, and improve overall quality of life.

Before beginning therapy, patients should undergo baseline liver function tests, blood counts, and pregnancy screening, as Bosentan may have significant side effects and drug interactions. Regular monitoring during treatment ensures safe use and allows dosage adjustments when necessary.
