Which anesthetic is a barbiturate that was historically used for rapid induction but is now less common due to the 'redistribution' effect terminating its action?
Show answer and explanation
Correct answer: Thiopental
Thiopental is a highly lipophilic ultra-short-acting barbiturate. Its effect on the brain ends not because of metabolism, but because the drug redistributes from the brain into less perfused tissues like muscle and fat.
