Key Concepts in Psychiatry-Pharmacology for USMLE:
1. Drug Mechanisms: Understand how various psychiatric medications work at a
biochemical level. This includes knowing which neurotransmitter systems are affected by
different classes of drugs (e.g., SSRIs increase serotonin levels, antipsychotics affect
dopamine pathways).
2. Drug Classes and Their Uses:
o Antidepressants: SSRIs, SNRIs, TCAs, MAOIs. Know their indications, side effects, and
drug interactions.
o Antipsychotics: Typical (first-generation) and atypical (second-generation). Be familiar
