Study Notes
First-Generation Antipsychotics (FGAs)
- Primarily work by blocking dopamine D2 receptors
- Used to treat schizophrenia and related disorders
- Potentially cause side effects such as:
- Extrapyramidal symptoms (EPS)
- Akathisia, parkinsonism, dystonia, tardive dyskinesia
- Neuroleptic malignant syndrome (NMS)
- Endocrine effects (e.g., galactorrhea, menstrual irregularities)
- Cardiovascular effects (e.g., orthostatic hypotension)
- Metabolic effects (e.g., weight gain, dyslipidemia)
- Several additional side effects
- Extrapyramidal symptoms (EPS)
Second-Generation Antipsychotics (SGAs)
- Often have a lower risk of EPS compared to FGAs
- May be more effective in treating negative symptoms of schizophrenia
- Potentially cause side effects such as:
- Metabolic effects (e.g., weight gain, dyslipidemia)
- Increased risk of diabetes
- Sexual dysfunction
Antidepressants
- May take several weeks to show effects
- Different classes with varying mechanisms of action
- Potentially cause side effects such as:
- Nausea/vomiting
- Sexual dysfunction
- Weight gain/loss
- Sleep disturbances
- Serotonin syndrome
- Anticholinergic effects (e.g., dry mouth, constipation)
Mood Stabilizers
- Used to treat bipolar disorder and other mood disorders
- Examples include: lithium and valproate
- Potentially cause side effects such as:
- Gastrointestinal problems (e.g., nausea, diarrhea)
- Tremor
- Weight changes
- Renal problems
- Thyroid problems
