Etomidate - 2


Etomidate is an ethyl ester of a carboxylated imidazole, specifically:


Only the R(+) enantiomer is hypnotically active; and etomidate is the only anesthetic agent marketed as only the active isomer.

Etomidate is insoluble and unstable in neutral water, so is prepared and marketed as etomidate (Amidate), 2 mg/ml in propylene glycol (35% by volume), pH 6.9, osmolality 4,640 mOsm/L.
