Ambrisentan
Ambrisentan
Ambrisentan (pronounced am-bri-sen-tan) is a type of medication used primarily in the treatment of pulmonary arterial hypertension (PAH). It belongs to a class of drugs known as endothelin receptor antagonists.
Etymology
The name "Ambrisentan" is derived from the chemical structure of the drug. "Ambri" is a prefix used in pharmaceutical nomenclature to denote a specific chemical structure, while "sentan" is a suffix commonly used for endothelin receptor antagonists.
Usage
Ambrisentan is used to treat pulmonary arterial hypertension (PAH), a condition characterized by high blood pressure in the arteries of the lungs. By blocking the action of endothelin, a substance in the body that constricts blood vessels and raises blood pressure, Ambrisentan helps to relax and widen the blood vessels in the lungs, thereby reducing blood pressure and improving symptoms.
