These complex mechanisms have been extensively studied in laboratory animals, but less is known of their incidence or importance in man. The pharmacokinetic interactions of widely used drugs could be of major clinical importance. This review focuses on a commonly prescribed group, the sedative, hypnotic, and antianxiety agents.
