Methohexital

Methohexital (Brevital) is an ultra-short-acting barbiturate anesthesia agent used for induction, procedural sedation, and ECT due to its rapid, 3-to-7-minute action and quick recovery. It functions by enhancing GABAergic neurotransmission, causing CNS depression, and is administered intravenously, intramuscularly, or rectally. Common side effects include apnea, hypotension, muscle twitching, and hiccups, with severe risks including respiratory depression.
