Summary
Etomidate, an anesthetic, causes significant side effects like injection pain and adrenal suppression. Newer agents offer better safety profiles, suggesting it
Area of Science:
- Anesthesiology and pharmacology.
- Drug development and clinical pharmacology.
Background:
- Etomidate is an intravenous hypnotic used in anesthesia and critical care.
- It is favored for hemodynamic stability and rapid onset/offset but has notable side effects: injection pain, myoclonus, and adrenocortical depression.
Discussion:
- Despite chemical modifications like methoxyethyl etomidate hydrochloride (ET-26), drawbacks persist.
- Alternatives such as propofol, ketamine, and remimazolam present fewer adverse effects.
- The persistent issues with etomidate and its derivatives question its continued development.
Key Insights:
- Etomidate's side effect profile, including pain and adrenocortical suppression, remains a significant clinical challenge.
- Attempts to chemically modify etomidate have yielded limited success in mitigating its adverse effects.
- Existing alternatives offer improved safety and tolerability compared to etomidate.
Outlook:
- The focus should shift from refining etomidate to developing novel anesthetic agents.
- Future research should prioritize agents with improved safety and efficacy profiles.
- Exploring new chemical entities for anesthesia may overcome the limitations of current drugs.

01:24Parenteral Anesthetics: Overview
96
Intravenous anesthetics are drugs administered parenterally to induce anesthesia or sedation. Propofol is a widely used agent formulated as a 1% emulsion in soybean oil, glycerol, and egg phosphatide. It induces rapid anesthesia primarily due to its rapid distribution from the bloodstream to target tissues and is metabolized in the liver. However, it can cause significant pain on injection and hypertriglyceridemia. Fospropofol, a water-based prodrug of propofol, lacks these adverse effects.

145
Sedatives and hypnotics encompass a wide range of substances, each with its unique mechanism of action, uses, and potential adverse effects.
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...

01:20Inhalational Anesthetics: Overview
176
Inhalation anesthetics are drugs that induce general anesthesia upon inhalation. They work by increasing the sensitivity of GABAA receptors or inhibiting NMDA receptors, leading to a decrease in central nervous system activity. The depth of anesthesia can be rapidly adjusted by changing the concentration of the inhaled gas. Some common examples of inhalational anesthetics include volatile liquids like isoflurane, desflurane, sevoflurane and gases like xenon and nitrous oxide. Isoflurane, a...

01:23Sedatives and Hypnotics: Overview
270
Sedatives are drugs that alleviate anxiety, while hypnotics induce sleep. Both classes of medication suppress neuronal activity, leading to a calming effect for sedatives and facilitating sleep for hypnotics.
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...

01:20Sedatives and Hypnotics Drugs: Barbiturates
192
Sedatives and hypnotics encompass a drug class that acts on the central nervous system (CNS) to alleviate anxiety, promote relaxation and induce sleep.These drugs function by amplifying the actions of the neurotransmitter γ-aminobutyric acid (GABA), resulting in reduced neuronal activity. Barbiturates, a subset of sedatives and hypnotics first synthesized in the late 1800s, are categorized into ultra-short, short, intermediate, and long-acting groups based on their duration of effect.

184
Benzodiazepines have both sedative and hypnotic properties. They include compounds such as diazepam (Valium) and alprazolam (Xanax). Structurally, their cores are similar, consisting of the fusion of a benzene ring and a diazepine ring, but they share a common mechanism of action in the central nervous system (CNS).
Benzodiazepines work by enhancing the effects of the inhibitory neurotransmitter GABA. They bind to the GABAA receptor, increasing its affinity for GABA, which opens chloride...
