- FGA (Typical): Low potency (Chlorpromazine, Thioridazine) vs. High potency (Haloperidol, Fluphenazine, Pimozide)
- SGA (Atypical): D2/5-HT2 blockers vs. Partial agonists (Aripiprazole, Cariprazine, Brexpiprazole)
- Chemical classes: Phenothiazines, Butyrophenones, Thioxanthenes
2. Dopamine Pathways - All 4 tracts (Mesolimbic, Mesocortical, Nigrostriatal, Tuberoinfundibular) with clinical implications
3. Mechanism of Action - D2 blockade, D2 + 5-HT2A (SGAs), partial agonism, glutamate hypothesis, clozapine's unique profile
4. Pharmacokinetics - Absorption, distribution, metabolism, depot (LAI) forms
5. Adverse Effects (most detailed section):

- NMS (FALTER mnemonic) with NMS vs. Serotonin Syndrome comparison
- Metabolic effects, QTc prolongation, clozapine-specific effects
6. Clinical Uses - Primary indications, non-psychotic uses, treatment algorithm
7. Drug Comparison Table - 10 major drugs compared across EPS, sedation, weight gain, prolactin, QTc
