  1. Common Toxic Syndromes
    P. 309 in pharm book Kaplan
  2. Heavy Metal Poisoning: ARSENIC
    • Where it is found: wood preservatives, pesticides, ant poisons)
    • Sxs: ACUTE: gastroenteritis, hypotension, metabolic acidosis, garlic breath, "rice water" stools, torsades, seizures CHRONIC: pallor, skin pigmentation (raindrop pattern), alopecial, stocking glove neuropathy, myelosuppression
    • Intervention/antidote: activated charcoal, dimercaprol, penicillamine or succimer
  3. Heavy Metal Poisoning: Iron
    • Where it is found: medicinal for anemias, prenatal vitamins)
    • Sxs: ACUTE: mainly children, severe GI distress, necrotizing gastrogeneteritis with hematemesis & blood y diarrhea, dysnpea, shock, coma (blood from both ends)
    • Intervention/antidote: gastric aspiration + carbonate lavage, deferoxamine IV
  4. Heavy Metal Poisoning: Lead
    • Where it is found: tap water, leaded pain chips, herbal remedies, gas sniffing, glazed kitchenware)
    • Sxs: ACUTE: nausea/vomiting, GI distress, pain, malaise, tremor, tinnitis, paesthesia, encephalopathy (red or black feces). CHRONIC: multisystem effects: anemia (decreased heme synthesis), neuropathy (wrist drop), nephropathy (proteinuria, failure), hepatitis, mental retardation (from pica), decreased fertility, increased stillbirths, will see Pb on Xray in long bones
    • Intervention/antidote: DECONTAMINATION: gastric lavage + dimercaprol (severe) or EDTA or succimer (penicillamine if unable to use dimercaprol or succimer), children: succimer PO
  5. Heavy Metal Poisoning: Mercury
    • Where it is found: elemental in instruments, salts in amalgams, batteries, dyes, electroplating, fireworks, photography
    • Sxs: ACUTE: vapour inhalation- chest pain, dyspnea, pneumonitis, inorganic ingestion- hemorrhagic gastrogenteritis, acute tubular necrosis, shock. CHRONIC: organic Hg- CNS effects, ataxia, paresthesias, auditory and visual loss, loosening of teeth
    • Interventions/antidote: succimer PO or dimercaprol (IM). Activated charcoal for ingestion, then support with succimer PO or dimercaprol (not IV) bc it causes redistribution of Hg to CNS = neurotoxicity
  6. Antidotes: (note chart on page 311 in kaplan)
    Acetaminophen poisioning
  7. Antidotes:
    AChEI inhibitors poisoning: physostigmine, neostigmine, pyridostigmine, organophsophates (insecticieds like malathion & parathion)
    Atropine + pralidoxime (or irreversible AChE inhibitors)
  8. Antidotes:
    Iron and Iron Salts
  9. Antidotes:
    Digoxin immune F(ab)
  10. Antidotes:
    Arsenic, gold, mercury, lead
    Oral succimer for milder lead and mercury toxicity, dimercaprol (BAL)
  11. Antidotes:
    theophylline, beta agonist
  12. Antidotes:
    Benzodiazepine, zolpidem, zalplon
  13. Antidotes:
    Opiod analgesics
  14. Antidotes:
    Carbon monoxite
  15. Antidotes:
    copper (Ex: Wilson's disease), iron, lead, mercury
  16. Antidotes:

    activate charcoal (time dependent though)
