Usage

Description

ACT-132577 is a drug compound that belongs to the family of endothelin receptor antagonists. It is an active metabolite of N-Despropyl-macitentan and is used for the treatment of pulmonary arterial hypertension (PAH). Endothelin receptor antagonists work by blocking the action of endothelin-1, a potent vasoconstrictor, thereby reducing blood vessel constriction and improving blood flow in PAH patients.

Uses

Used in Pharmaceutical Industry:
ACT-132577 is used as a therapeutic agent for the treatment of pulmonary arterial hypertension (PAH). It functions as an endothelin receptor antagonist, which helps in reducing the constriction of blood vessels and improving blood flow in PAH patients. This makes it a valuable drug for managing the symptoms and progression of PAH, ultimately improving the quality of life for those affected by the condition.
