Substance Name: Halothane [USP:INN:BAN:JAN]
RN: 151-67-7
UNII: UQT9G45D1P
InChIKey: BCQZXOMGPXTTIC-UHFFFAOYSA-N

Note

  • A nonflammable, halogenated, hydrocarbon anesthetic 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. (From AMA Drug Evaluations Annual, 1994, p178)
