Brompton cocktail, sometimes called Brompton mixture or Brompton's cocktail, was an elixir meant for use as a pain suppressant dosed for prophylaxis. Made from morphine or diacetylmorphine (heroin), cocaine, highly-pure ethyl alcohol (some recipes specify gin), and sometimes with chlorpromazine (Thorazine) to counteract nausea, it was given to terminally-ill individuals (especially cancer patients) to relieve pain and promote sociability near death. A common formulation included "a variable amount of morphine, 10 mg of cocaine, 2.5 mL of 98% ethyl alcohol, 5 mL of syrup BP and a variable amount of chloroform water." Brompton's cocktail was given most in the mid twentieth century. It is now considered obsolete.
