Bosentan is used to treat high blood pressure in a condition called pulmonary arterial
hypertension, which effects the lungs. PAH is a condition that is caused by increased levels
of an endothelin-1 in the body. It reduces the number of open wounds, especially on
fingertips and knuckles. Bosentan is a dual endothelin receptor antagonist, in that it
selectively inhibits the production of the substance Endothelin-1. The goal of Bosentan
therapy is to improve ability to exercise and slow the progression of the disease. Bosentan has
been shown effectiveness mostly in patients with symptoms that were rated as WHO
Functional Class II-III.

How does Bosentan work?
Bosentan is an antagonist of endothelin-1. When functioning normally, endothelin-1 causes the
pulmonary blood vessels to constrict. Endothelin also causes abnormal growth of the muscle
of the blood vessels in the lungs thus narrowing passages. This increases the pressure
required to push the blood through the lungs to get oxygen. Conversely, Endothelin-1 has
been associated with both vasodilation and vasoconstriction of vascular smooth muscle and
tissue. Bosentan blocks the receptors, causing a total decrease in pulmonary vascular
Bosentan blocks off the effects of endothelin-1, which helps lower blood pressure in the
lungs, slow the worsening of symptoms from the disease. Because it can reduce the stress on
the lungs it also improves our ability to exercise and related research studies have verified
