The 60-year-old classification system of the approximately 150 medications utilized for the treatment of psychiatric disorders (antipsychotics, antidepressants, mood stabilizers, sedative-hypnotics, etc.) is being replaced by a neuroscience-based nomenclature.

Using clinical vignettes, the application of this system to the pharmacological treatment of different psychiatric disorders will be summarized.
