ABSTRACT
In the preceding chapters the pharmacological actions of analgesics and other drugs used to facilitate analgesia have been described, as have the basic approaches to be used by the physician confronted with a patient in pain. Although the information presented is applicable regardless of the etiology of the pain, there are certain groups who may be particularly sensitive to drug effects or who, by virtue of an underlying medical or psychologic disorder, may be particularly recalcitrant to therapy.
