Pharmacology of Antidepressants and Mood Stabilizers

This topic covers the pharmacology of drugs used to treat mood disorders, including tricyclic antidepressants (TCAs) like amitriptyline, selective serotonin reuptake inhibitors (SSRIs), monoamine oxidase inhibitors (MAOIs), and mood stabilizers such as lithium and valproate. For Zambian university students in medicine, psychiatry, and clinical pharmacy, this knowledge is essential for managing depression, bipolar disorder, and anxiety disorders in clinical practice. The content explores mechanisms of action, such as reuptake inhibition and enzyme blockade, pharmacokinetics, therapeutic drug monitoring for lithium, and serious adverse effects like cardiac arrhythmias, serotonin syndrome, and lithium toxicity. Understanding these drug classes is crucial for passing pharmacology and psychiatry examinations and for safe prescribing during clinical rotations in Zambian mental health units. This topic prepares tertiary learners to develop effective, individualized treatment plans, contributing to the improvement of mental healthcare services within Zambia's tertiary health institutions and addressing a significant public health need.
