Psychiatry Pharmacology Basics and Critical Thinking

This topic reviews essential psychiatric pharmacology, covering major drug classes including antipsychotics, antidepressants, mood stabilisers, anxiolytics, and atypical agents, with their therapeutic uses, key side effects, and critical safety considerations. It emphasises priority nursing actions, such as monitoring for neuroleptic malignant syndrome, agranulocytosis, lithium toxicity, and drug–food interactions (e.g., tyramine with monoamine oxidase inhibitors, or MAOIs), as well as timing and administration strategies to optimise efficacy and minimise risk. By integrating neurotransmitter functions, pharmacokinetics, and pharmacodynamics, nurses are equipped to make informed clinical decisions and provide safe and effective medication management for psychiatric patients.
