Etomidate offers cardiovascular stability and potential neuroprotection, but causes adrenal suppression and myoclonus. Recent advances include a new formulation and pretreatment to mitigate side effects.
Area of Science:
- Anesthesiology and Pharmacology
Background:
- Etomidate is an anesthetic agent known for its lack of cardiovascular side effects.
- It is also suggested to possess neuroprotective properties.
- However, known side effects include adrenal suppression and myoclonus.
Purpose of the Study:
- To review recent literature on etomidate.
- To discuss its clinical applications, adverse effects, and mechanism of action.
Main Methods:
- A comprehensive literature review was conducted.
Main Results:
- Recent advancements include a new etomidate preparation free from propylene glycol and its associated side effects.
- A novel pretreatment method has been developed to potentially decrease the occurrence of myoclonus.
- The specific site of action for etomidate within the central nervous system has been identified.
Conclusions:
- Etomidate remains a valuable anesthetic due to its hemodynamic stability.
- Ongoing research is addressing its side effect profile, particularly adrenal suppression and myoclonus.
- Advances in formulation and administration aim to improve patient outcomes and expand its clinical utility.

Sedatives and Hypnotics: Overview
Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...
