Showing 1–4 of 4 questions
Q1 · Organophosphate Poisoning
NEET PGEasyExplanation
Organophosphates inhibit acetylcholinesterase, causing a cholinergic crisis (DUMBELS). Atropine blocks the muscarinic effects while pralidoxime reactivates the enzyme if given before ageing of the enzyme-inhibitor complex.
Q2 · Paracetamol Antidote
NEET PGEasyExplanation
N-acetylcysteine replenishes hepatic glutathione, allowing conjugation and clearance of the toxic metabolite NAPQI. It is most effective within 8 hours of ingestion and prevents hepatic necrosis.
Q3 · Methanol Poisoning
MediumExplanation
Fomepizole inhibits alcohol dehydrogenase, preventing conversion of methanol to toxic formic acid, which causes the visual loss and acidosis. Ethanol is an alternative competitive substrate, and haemodialysis removes methanol in severe cases.
Q4 · Beta Blocker Overdose
HardExplanation
Glucagon raises intracellular cAMP through a receptor independent of the beta adrenergic receptor, restoring heart rate and contractility in beta blocker overdose refractory to atropine. High-dose insulin-euglycaemia therapy is an adjunct.
Toxicology and Antidotes sits within Pharmacology, which carries the same syllabus in both exams. This set runs to 4 questions, each tagged Easy, Medium or Hard, 1 of them at Hard, and 2 drawn from previous-year papers.
Answer first, then read the explanation even on the ones you got right — the reasoning is where Toxicology and Antidotes marks are actually won, and it is what separates a recalled fact from a question you can solve in a new form. Once the Easy set feels comfortable, filter to Hard to find the gaps Pharmacology examiners keep returning to.
FAQ

Toxicology and Antidotes sits within Pharmacology, which appears in the same form in both syllabuses. Drug classes, mechanisms and adverse effects. One of the highest yield subjects per hour of study, because the same drugs recur across cycles.
