Psychopharmacology algorithms

Psychopharmacology Algorithms, 2nd Edition provides thirteen evidence-based treatment algorithms developed by the Harvard South Shore Psychiatry Program. Each algorithm offers clear, practical guidance for selecting psychiatric medications, supported by critical evaluation, updated recommendations, and detailed rationale for every step.

Psychopharmacology Algorithms, Second Edition is a unique, authoritative, and highly practical clinical reference that translates the best available psychiatric research into clear, evidence-based treatment pathways for everyday patient care. Developed from the renowned Psychopharmacology Algorithm Project at the Harvard South Shore Psychiatry Residency Training Program, this essential text is prepared by leading expert Dr. David N. Osser and is widely recognized for its rigor, clarity, and clinical relevance.

Unlike traditional psychopharmacology textbooks, this book presents thirteen carefully constructed psychopharmacology treatment algorithms designed to guide clinicians through the safe, rational, and effective use of psychiatric medications. Each algorithm is grounded in a thorough critical appraisal of the scientific evidence, offering transparent explanations of the clinical rationale behind each treatment decision, along with the advantages, limitations, and alternatives to recommended interventions.

Each chapter provides:

• Background on the development and purpose of the algorithm

• A node-by-node walkthrough of treatment decisions

• Clear flowcharts for quick reference in clinical settings

• Key clinical takeaways to support evidence-based prescribing

• The full original algorithm paper, followed by updated recommendations where newer evidence warrants changes

The Second Edition includes four all-new algorithms addressing some of the most challenging and high-impact clinical scenarios in contemporary psychiatric practice:

• Management of agitation in acute psychotic and manic episodes

• Treatment of generalized anxiety disorder in older adults

• Pharmacologic approaches to core symptoms of autism spectrum disorder in adults

• Management of behavioral and psychological symptoms in dementia

All algorithms from the first edition have been thoroughly updated to reflect the latest research, medications, and clinical guidelines. In addition, the accompanying eBook includes new video lectures by Dr. Osser, recorded specifically for this edition. Each in-depth lecture—often one hour or longer—provides expert commentary, clinical pearls, and real-world prescribing insights that enhance understanding and application of the algorithms.

The book also features introductory chapters that examine the evidence base supporting clinical algorithms and offer guidance on how to integrate algorithm-based decision-making into routine psychiatric practice effectively and flexibly.

Ideal for practicing psychiatrists, psychiatry residents and fellows, psychiatric nurse practitioners, physician assistants, advanced practice pharmacists with prescribing authority, primary care clinicians, as well as psychopharmacology educators and researchers, Psychopharmacology Algorithms, Second Edition is an indispensable resource for clinicians committed to safe prescribing, evidence-based psychiatry, and improved patient outcomes.
