In every central and state government pharmacist competitive examination (including Railway RRB CEN 05/2026, ESIC, AIIMS CRE, UPSSSC, and State NHM), factual questions from Pharmacology Antidotes, First-Line Drugs of Choice, Statutory Schedules of the Drugs and Cosmetics Act 1940, and Pharmacopoeial Storage Temperatures consistently account for 25 to 35 direct marks.
To help aspirants revise quickly during the final preparation window, we have consolidated these essential recurring topics into official, structured comparison tables based on the Indian Pharmacopoeia (IP), statutory CDSCO rules, and standard clinical pharmacology guidelines.
Table 1: Complete Specific Antidotes Chart for Poisoning & Drug Toxicities
| Toxic Agent / Poison | Specific Antidote | Mechanism of Action / Clinical Note |
|---|---|---|
| Paracetamol (Acetaminophen) | N-Acetylcysteine (NAC) | Replenishes hepatic glutathione stores; conjugates toxic metabolite NAPQI. |
| Unfractionated Heparin | Protamine Sulfate | Strongly basic protein binds acidic heparin ionically to form an inactive salt complex. |
| Warfarin (Coumarin Anticoagulants) | Phytomenadione (Vitamin K1) | Promotes hepatic synthesis of functional clotting factors II, VII, IX, and X. |
| Opioids (Morphine, Heroin, Codeine) | Naloxone (Narcan) | Pure competitive opioid receptor antagonist at mu (μ), kappa (κ), and delta (δ) receptors. |
| Benzodiazepines (Diazepam, Alprazolam) | Flumazenil | Competitive antagonist at the benzodiazepine binding site on GABA-A receptor complex. |
| Organophosphates & Carbamates | Atropine + Pralidoxime (2-PAM) | Atropine blocks muscarinic excess; Pralidoxime reactivates phosphorylated acetylcholinesterase. |
| Digoxin (Digitalis Glycosides) | Digoxin Immune Fab (DigiFab) | Antigen-binding fragments bind free intravascular digoxin and promote renal excretion. |
| Iron Toxicity (Acute Overdose) | Deferoxamine (Desferrioxamine) | Chelates free ferric (Fe3+) iron to form water-soluble ferrioxamine, excreted in urine (vin rose urine). |
| Lead (Plumbism) & Heavy Metals | Calcium Disodium EDTA / Dimercaprol (BAL) | Chelating agents forming stable non-toxic coordination complexes with heavy metal cations. |
| Copper Toxicity / Wilson’s Disease | D-Penicillamine / Trientine | Chelates excess copper and enhances urinary excretion. |
| Cyanide Poisoning | Hydroxocobalamin / Sodium Nitrite + Thiosulfate | Forms cyanocobalamin; nitrites induce methemoglobinemia which binds cyanide. |
| Methanol & Ethylene Glycol | Fomepizole (4-Methylpyrazole) or Ethanol | Inhibits alcohol dehydrogenase (ADH), preventing formation of toxic formic/oxalic acid. |
| Beta-Blocker Overdose | Glucagon IV | Stimulates myocardial adenylate cyclase directly, bypassing blocked beta-adrenergic receptors. |
| Methotrexate Overdose | Leucovorin Calcium (Folinic Acid) | Rescues normal bone marrow cells by bypassing dihydrofolate reductase (DHFR) inhibition. |
| Isoniazid (INH) Induced Neurotoxicity | Pyridoxine (Vitamin B6) | Overcomes competitive inhibition and renal loss of pyridoxal-5-phosphate. |
| Anticholinergic Toxicity (Atropine, Datura) | Physostigmine | Tertiary amine reversible acetylcholinesterase inhibitor that crosses blood-brain barrier. |

| Absence Seizures (Petit Mal Epilepsy) | Ethosuximide (or Sodium Valproate) | Oral |
| Generalized Tonic-Clonic Seizures (GTCS) | Sodium Valproate | Oral / IV |

| Acute Gouty Arthritis Attack | NSAIDs (Indomethacin) / Colchicine | Oral |
| Chronic Gout (Uric Acid Reducer) | Allopurinol / Febuxostat | Oral |
| MRSA (Methicillin-Resistant S. aureus) | Vancomycin | IV Infusion |
| Syphilis (Treponema pallidum) | Benzathine Penicillin G | Intramuscular (IM) |
| Type-2 Diabetes Mellitus (First-Line) | Metformin (Biguanide) | Oral |
| Hypothyroidism | Levothyroxine (T4) | Oral (Empty Stomach) |
| Hypertension in Pregnancy (Pre-Eclampsia) | Labetalol / Methyldopa / Hydralazine | Oral / IV |
| Eclampsia (Seizure Prophylaxis & Control) | Magnesium Sulfate (MgSO4) | IV / IM (Pritchard regimen) |

Frequently Asked Questions (FAQ) — Pharmacist High-Yield Revision:
Q1: Which subjects carry the maximum weightage in Government Pharmacist CBT exams?
Answer: Pharmacology & Toxicology and Pharmaceutics collectively carry 50% to 60% of technical marks across RRB, ESIC, and AIIMS. Key high-yield scoring chapters include autonomic nervous system (ANS), cardiovascular drugs, antibiotics, biopharmaceutics, sterilization kinetics, and statutory D&C Act schedules.
Q2: What is the mandatory retention period for Schedule H1 drug registers?
Answer: Under the Drugs and Cosmetics Rules 1945, the separate register containing patient details, prescribing doctor’s name, and drug quantities for Schedule H1 substances must be preserved for a minimum period of 3 years from the date of the last entry. In contrast, Schedule X prescription duplicates are preserved for 2 years.
Q3: What is the official vaccine cold chain temperature standard in government hospitals?
Answer: The national cold chain guideline and Indian Pharmacopoeia mandate storing all routine vaccines (except long-term OPV) strictly between +2°C and +8°C with continuous twice-daily digital temperature logger monitoring.
