Method for reducing emesis and nausea induced by the administration of an emesis causing agent

摘要

A method for preventing or relieving nausea and emesis associated with the use of an emesis-causing agent in warm-blooded animals comprises administering to the animal both a narcotic analgesic and a quaternary derivative of noroxymorphone prior to, simultaneously with of after administering the emesis-causing agent. A particularly preferred noroxymorphone derivative is methylnaltrexone. The method is highly effective in preventing or relieving nausea and emesis induced by anticancer drugs, and by apomorphine.
