DABAT study plan
DABAT · Give each week a clear focus.
8 weeks · About 7 hours per week
Scientific and Clinical Foundations of Toxicology
Build a one-page map of core toxicology principles (dose-response, threshold, hormesis, NOAEL/LOAEL, TD50/LD50) and state where each concept is used clinically versus regulatorily
Explain xenobiotic absorption, distribution, and biotransformation phases I and II, naming the major CYP and conjugation enzyme families and two clinically important polymorphisms for each
Differentiate the principal target-organ toxic syndromes (hepatotoxicity, nephrotoxicity, neurotoxicity, cardiotoxicity, hematotoxicity, pulmonary toxicity) by hallmark mechanism and representative agent
Work through 40 domain-1 style questions and log every missed concept with a corrected one-sentence explanation
Your checkpoint
A 2-page condensed 'scientific foundations' cheat sheet plus an error log of at least 15 corrected concepts
Pharmacokinetics and Toxicokinetics
Derive and apply first-order versus zero-order elimination equations, including half-life, volume of distribution, clearance, and steady-state relationships
Calculate loading and maintenance doses and interpret how altered protein binding, hepatic extraction ratio, and renal function change them
Explain toxicokinetic concepts: apparent volume of distribution exceeding body water, flip-flop kinetics, enterohepatic recirculation, and saturated metabolism producing prolonged toxicity
Interpret a two-compartment decay curve and identify the distribution and elimination phases for a named overdose scenario
Complete 30 calculation problems with at least 85% accuracy, reworking every error until correct
Your checkpoint
A timed 20-question pharmacokinetics problem set scored and annotated with the formula used for each item
Mechanisms of Toxicity and Toxicodynamics
Distinguish receptor-mediated, enzyme-inhibiting, membrane-disrupting, and metabolic-activation mechanisms of toxicity and match each to a prototype toxin
Explain how reactive metabolites and free radicals cause covalent binding, lipid peroxidation, and glutathione depletion, using acetaminophen as the working example
Describe oxygen delivery versus utilization failure (hypoxia, histotoxic anoxia, methemoglobinemia, carboxyhemoglobinemia) and how each alters pulse oximetry and co-oximetry
List the mechanisms of ion-channel blockade relevant to sodium channel blocker and potassium channel blocker cardiotoxicity and predict ECG findings
Answer 30 mechanism-to-clinical-sign questions and justify each answer in one sentence
Your checkpoint
A mechanism-to-signature table linking at least 20 toxins to their primary mechanism, target organ, and expected clinical or laboratory finding
Risk Assessment and Regulatory Toxicology
Walk through the four steps of risk assessment and name the uncertainty factors used in deriving reference doses and reference concentrations
Distinguish hazard identification, dose-response assessment, exposure assessment, and risk characterization using one industrial chemical example end to end
Explain how regulatory frameworks differ for pesticides, industrial chemicals, pharmaceuticals, and occupational exposures, including the roles of major national and international bodies
Interpret cancer slope factors, unit risk, and benchmark dose concepts well enough to compare two exposure scenarios
Complete a 25-question regulatory and risk-assessment set with written rationale for each distractor rejected
Your checkpoint
A worked risk-assessment case study for one chemical showing exposure estimate, reference value selection, and a defensible risk conclusion
Clinical Assessment and Diagnosis of the Poisoned Patient
Build a systematic approach to the poisoned patient: stabilization, history, toxidrome recognition, and focused physical examination
Differentiate the six classic toxidromes by vital signs, pupils, skin, bowel sounds, and mental status, and name two confounders for each
Select and interpret the core laboratory and bedside tests, including anion and osmolal gaps, co-oximetry, lactate, and ECG intervals, and state their limitations
Explain the indications, timing, and interpretation of drug screens and therapeutic drug monitoring, including false positives and false negatives
Complete 40 clinical vignettes in which you name the toxidrome, the likely agent, and the two most urgent next steps
Your checkpoint
A toxidrome comparison grid plus a scored set of 40 vignettes with documented reasoning
Management and Treatment of Poisoning (Decontamination, Antidotes, Enhanced Elimination)
Sequence decontamination decisions (gastrointestinal decontamination, skin and eye decontamination, and enhanced elimination) by indication, contraindication, and time since exposure
Match at least 20 antidotes to their toxins, stating mechanism, indication, dose principle, and major adverse effect for each
Compare methods of enhanced elimination (urinary alkalinization, hemodialysis, hemoperfusion, multidose activated charcoal) by the physicochemical properties that make a toxin amenable to each
Explain the rationale and limits of extracorporeal treatment criteria for salicylate, lithium, methanol, and ethylene glycol poisoning
Answer 40 management questions, weighting antidote selection and elimination decisions, and review every error
Your checkpoint
An antidote and enhanced-elimination reference table covering at least 20 agents with mechanism, indication, and key caution
Drugs of Abuse, Withdrawal, and Addiction Toxicology
Classify major drugs of abuse by pharmacologic class and describe the acute intoxication syndrome and the withdrawal syndrome for each
Explain the pathophysiology and timeline of alcohol withdrawal and the role of cross-tolerant agents in withdrawal management
Describe opioid overdose recognition and the pharmacology of reversal, including the risk of precipitated withdrawal and re-narcotization
Discuss stimulant, sedative-hypnotic, and hallucinogen intoxication patterns and the absence or presence of a true withdrawal syndrome
Answer 35 questions on intoxication and withdrawal and write a short differential for each withdrawal scenario
Your checkpoint
A two-column intoxication-versus-withdrawal chart for at least 10 substance classes, plus a scored 35-question set
Environmental, Occupational, and Industrial Toxicology
Characterize the major environmental and occupational exposure routes and the surveillance and exposure-limit concepts used in workplace settings
Explain the toxicology of priority agents such as lead, mercury, arsenic, cadmium, carbon monoxide, organophosphates, and solvents, including biomonitoring markers
Describe the recognition and management principles for mass-exposure and hazardous-materials incidents, including decontamination of responders
Integrate all eight domains by completing two full-length timed practice exams and reviewing every error by domain
Rank remaining weak domains and schedule targeted review of the three lowest-scoring areas before exam day
Your checkpoint
Two completed timed practice exams with a per-domain score report and a written remediation plan for the three weakest domains
