  • Introduction: Local anaesthetics reversibly block neural transmission in local tissues. The drugs are bound with specific receptors located inside the sodium channels of cell membranes, and thus block the permeability of sodium ions; this is the mechanism of anaesthetic action of these drugs. As the history of local anaesthetics, Von Anrep discovered the local anaesthetic action of an alkaloid cocaine being contained in the leaves of Erythroxylon coca. Then, Karl Koller used cocaine as a local anaesthetic in ophthalmological surgery.

  • Introduction: Cocaine is an alkaloid being contained in the leaves of Erythroxylon coca Lam. or Erythroxylon novogranatense (Morris) Hieronymus of Erythroxylaceae plants. The compound is being used as a local anaesthetic. It also shows stimulating action on the central nervous system; when it is used continuously, psychic dependence on its use appears, resulting in its chronic toxicosis [1]. Cocaine is being abused worldwide; its abuse is most serious in the north and south American continents. Fortunately, in Japan, its abuse is not so many; but it cannot be overlooked.
