Endothelin receptor antagonist

An endothelin receptor antagonist is a drug that blocks endothelin receptors.

Classes

Three main kinds of ERAs exist:

Dual ET Receptor Antagonists, which affect both endothelin A and B receptors is an example of a dual receptor endothelin receptor antagonist.
* aprocitentan, bosentan, macitentan, tezosentan, Feloprentan,
Selective ET_A Receptor Antagonists, which affect endothelin A receptors
* sitaxentan, ambrisentan, atrasentan, BQ-123, sparsentan, zibotentan, avosentan, edonentan, clazosentan, Fandosentan
Selective ET_B Receptor Antagonists, which affect endothelin B receptors
* BQ-788 and A192621 are used in research but have not yet reached clinical trial stage

Macitentan, ambrisentan and bosentan are mainly used for the treatment of pulmonary arterial hypertension, while atrasentan is an experimental anti-cancer drug.
