Stahl´s Essential Psychopharmacology has established itself as the preeminent source of education and information in its field. This much-expanded third edition relies on advances in neurobiology and recent clinical developments to explain the concepts underlying drug treatment of psychiatric disorders. New neurotransmitter systems; theories on schizophrenia; clinical advances in antipsychotic and antidepressant therapy; coverage of attention deficit disorder and drug abuse; and new coverage of sleep disorders, chronic pain, and disorders of impulse control. The fully revised text is complemented with many new, instructive and entertaining illustrations, their captions may be used independent of the main text for a rapid introduction to the field or for review.
