Avosentan is an oral endothelin receptor A antagonist which was developed by Roche and then licensed by Speedel (now Novartis). The drug was tested in phase III of clinical trials in patients suffering from diabetic nephropathy, however drug development was terminated due to safety reasons: avosentan caused severe heart failure and even deaths.

Porcine ciliary arteries were incubated with avosentan (10(-6) M and 10(-8) M) and then exposed, cumulatively, to increasing concentrations of endothelin-1 (10(-12) M-3 × 10(-8) M). Avosentan had a strong inhibitory effect on the endothelin-1-induced contractions. The inhibitory effect of 10(-6) M avosentan was significantly stronger than the effect of 10(-8) M avosentan.
