Zibotentan

Zibotentan is an experimental medication designed to block the effects of endothelin, a substance in the body that constricts blood vessels and can promote the growth of certain tumors. By inhibiting endothelin, zibotentan aims to improve blood flow and potentially slow the progression of diseases like prostate cancer and other conditions involving abnormal cell growth or blood vessel constriction. It is still under clinical research and not yet widely available, but it represents a targeted approach to treating these diseases by addressing specific biological pathways.
