Clinical experience with oral methadone administration in the treatment of pain in 196 advanced cancer patients.

Abstract

Oral methadone administered every 8 hours was shown to be an appropriate analgesic therapy in the treatment of advanced cancer-related pain. The worsening of the other symptoms under study can be considered linked to the progression of the disease, and in fact, only a small percentage of the patients reported methadone-related side effects that warranted suspension of treatment. We consider oral methadone to be a useful analgesic therapy, and it should be considered in clinical practice for the treatment of cancer pain.
