About this active substance

Bosentan is a medication used for the treatment of pulmonary arterial hypertension (PAH), a condition characterized by increased pressure in the pulmonary arteries. It is an endothelin receptor antagonist that helps relax blood vessels and reduce blood pressure.

The medication is taken orally, usually twice daily, as directed by a doctor. The treatment requires regular monitoring, including blood tests to assess liver function.

Common side effects include headaches, edema, fatigue, and elevated liver enzyme levels. In rare cases, more severe adverse effects such as liver failure or anemia may occur.

Bosentan is not recommended for pregnant women, as it may cause birth defects. Patients should use effective contraception during treatment and inform their doctor about any other medications they are taking to avoid drug interactions.
