A nonflammable, halogenated, hydrocarbon anaesthetic that provides relatively rapid induction with little or no excitement. Analgesia may not be adequate. Nitrous oxide is often given concomitantly. Because halothane may not produce sufficient muscle relaxation, supplemental neuromuscular blocking agents may be required.

Pharmacological action: anaesthetics, inhalation.

Chemical name: Ethane, 2-bromo-2-chloro-1,1,1-trifluoro-
