Evaluation of mean arterial blood pressure, heart rate, and sympathetic nerve activity in rabbits after administration of two formulations of etomidate

Etomidate in the commercial drug product is solubilized with propylene glycol, a cosolvent associated with adverse side effects on injection. An aqueous formulation of etomidate has been developed, which utilizes SBE-CD as a solubilizing agent. The data suggest that the SBE-CD etomidate formulation may be a safer IV induction formulation than the commercial etomidate drug product.
