    Study Notes

    Antidepressants Overview

    • Lithium: Used as a mood stabilizer, particularly in bipolar disorder.
    • SSRIs: New class of antidepressants, effective for depression and anxiety disorders.

    Tricyclic Antidepressants (TCAs)

    • Therapeutic Uses:

      • Treats depression and panic disorders.
      • Used for nocturnal enuresis (bedwetting) in children.
      • Prophylaxis for migraines.

    • Skin Manifestations:

      • Can cause blisters (bullae) over pressure points, particularly on hands and feet.

    • Gastrointestinal Issues:

      • Notable for diminished bowel sounds, indicating reduced intestinal activity.

    Distinguishing Features

    • Comparison to Barbiturates:

      • Barbiturate poisoning may lead to hypothermia and bullae formation, distinct from TCAs.

    • Common Lab Findings:

      • Hyperglycemia is common due to insulin release suppression from the pancreas.
      • Electrolyte imbalances may occur, including hypokalemia or hyperkalemia.
      • Lactic acidosis may develop.

    Treatment Protocols

    • Immediate Interventions:

      • Follow ABCs (Airway, Breathing, Circulation) measures for resuscitation.

    • Gastrointestinal Decontamination:

      • Important in cases of overdose or severe toxicity.

    • Hypokalemia Management:

      • Chronic toxicity risk due to loop diuretics, diarrhea, or inadequate dietary potassium intake.

    Investigations

    • Cardiac:

      • Monitor for severe refractory shock and hypotension.

    • Respiratory:

      • Look for pulmonary edema, cough, and dyspnea.

    • Hepatic:

      • Centrilobular necrosis may be indicative of significant liver damage.

    • Metabolic:

      • Assess for signs of metabolic acidosis which could complicate patient condition.
