Tezosentan

Tezosentan is a medication designed to help treat severe heart and lung problems related to high blood pressure in the lungs, known as pulmonary edema. It works by blocking a specific substance called endothelin, which causes blood vessels to tighten. By blocking endothelin, Tezosentan helps relax and widen blood vessels, reducing the pressure in the lungs and improving breathing. It is typically administered in hospital settings to critically ill patients, especially during surgeries or treatments where blood pressure management is crucial. However, it’s used with caution due to potential side effects like low blood pressure and other complications.
