halothane hal·o·thane (hāl'ə-thān')
A colorless, nonflammable liquid that is widely used as an inhalation anesthetic and that takes effect rapidly and can be rapidly counteracted.
nonflammable, volatile, liquid drug introduced into medicine in the 1950s and used as a general anesthetic. Halothane rapidly achieved acceptance and became the most frequently used of the potent anesthetics, despite its substantially higher cost than ether and chloroform and its tendency to depress respiration and circulation.
