Bosentan 62.5mg tablet contains Bosentan, an oral endothelin receptor antagonist used primarily for the treatment of pulmonary arterial hypertension (PAH). It works by blocking endothelin-1, a substance in the body that causes blood vessels to constrict. By inhibiting endothelin receptors (ETA and ETB), Bosentan helps relax and widen pulmonary blood vessels, reducing pulmonary vascular resistance and improving blood flow. Bosentan 62.5mg is commonly prescribed to improve exercise capacity, delay disease progression, and reduce symptoms such as shortness of breath and fatigue in patients with PAH. It may also be used in certain cases of systemic sclerosis to prevent new digital ulcers. This medication requires regular liver function monitoring due to potential hepatic side effects and should be taken strictly under medical supervision.
