[PHARM-10] Clinical Toxicology, Emergency Resuscitation Antidotes & Immunopharmacology
PHARM-10 • 10. Clinical & Hospital PharmacyLearning Objectives
Pair every major clinical toxin and drug overdose with its specific antidote, mechanism, and emergency dosing from Chapter 12 and Appendix B.; Contrast intramuscular vs intravenous Adrenaline ([12.32] vs [App-B.1]) across anaphylaxis and cardiac arrest (ACLS) to eliminate 10-fold dilution medication errors.; Classify snakebite envenomation syndromes in India ('Big Four') and anti-snake venom (ASV) reaction management.
Chapter Overview & Core Explanation
Clinical toxicology and emergency pharmacology focus on rapid stabilization of airway, breathing, and circulation (ABCs) followed by targeted antidotes that neutralize poisons, displace toxins from receptors, or regenerate essential enzymes.
Key Exam & Clinical Takeaways
- Always verify Adrenaline concentration (1:1,000 IM for anaphylaxis vs 1:10,000 IV for cardiac arrest) before administration.
- [12.36] Naloxone has a shorter half-life (30–60 min) than Morphine or Methadone; patients must be observed for recurrent respiratory depression (renarcotization).
