🔹 Verified Syllabus (Pharmacology & Toxicology – Detailed)

1. Pharmacokinetics (ADME)

  • Absorption: passive diffusion, facilitated diffusion, active transport, bioavailability factors
  • Distribution: protein binding, tissue distribution, volume of distribution
  • Metabolism: Phase I (oxidation, reduction, hydrolysis) & Phase II (glucuronidation, sulfation, acetylation, methylation)
  • Elimination: renal excretion, biliary excretion, clearance concepts
  • Half-life & kinetics (zero-order, first-order, Michaelis–Menten)

2. Pharmacodynamics

  • Dose-response relationship (graded & quantal)
  • Potency, efficacy, therapeutic index, safety margin
  • Receptor theories: lock & key, induced fit, signal transduction pathways
  • Agonists, antagonists, partial agonists, inverse agonists

3. Drug Metabolism & Enzyme Kinetics

  • Cytochrome P450 system
  • Enzyme induction & inhibition
  • Prodrugs and bioactivation pathways

4. Drug Interactions & Adverse Drug Reactions (ADRs)

  • Pharmacokinetic vs pharmacodynamic interactions
  • Idiosyncratic & allergic reactions
  • Classification of ADRs (Type A–F)
  • Drug safety monitoring (pharmacovigilance)

5. Mechanism of Action of Common Drug Classes

  • Antihypertensives: ACE inhibitors, ARBs, beta-blockers, calcium channel blockers
  • Antibiotics: beta-lactams, aminoglycosides, tetracyclines, fluoroquinolones
  • Analgesics: opioids, NSAIDs
  • Anticancer agents: alkylating agents, antimetabolites, targeted therapies

6. Receptor–Ligand Interactions

  • G-protein coupled receptors
  • Ion channel-linked receptors
  • Enzyme-linked receptors
  • Nuclear receptors

7. Pharmacological Screening Methods

  • In vivo vs in vitro studies
  • Preclinical models for CNS, CVS, endocrine system, etc.
  • Dose selection & interpretation of pharmacological results

8. Toxicology

  • Principles of toxicology
  • Acute, sub-acute, chronic toxicity studies
  • Organ-specific toxicities (hepatic, renal, cardiac, CNS)
  • Teratogenicity, mutagenicity, carcinogenicity tests
  • Antidotes for common poisonings

9. Neuropharmacology

  • CNS stimulants (amphetamines, methylxanthines)
  • CNS depressants (barbiturates, benzodiazepines, anesthetics)
  • Psychotropic drugs (antidepressants, antipsychotics, mood stabilizers)
  • Drugs of abuse and dependence

 

🔹 MCQ Collection (Sample)

Question: Which phase of drug metabolism is primarily responsible for conjugation reactions?
a) Phase I – Oxidation
b) Phase I – Reduction
c) Phase II – Conjugation
d) Phase I – Hydrolysis

Answer: c) Phase II – Conjugation

Explanation: 📌 Phase II metabolism (conjugation reactions) involves glucuronidation, sulfation, acetylation, and methylation, making drugs more water-soluble for elimination. Phase I mainly includes oxidation, reduction, and hydrolysis. ✅

Time Limit: 60 seconds

Question: Which receptor is primarily targeted by benzodiazepines?
a) NMDA receptor
b) GABA-A receptor
c) Dopamine D2 receptor
d) Serotonin 5-HT2 receptor

Answer: b) GABA-A receptor

Explanation: ✅ Benzodiazepines enhance the effect of the inhibitory neurotransmitter GABA at the GABA-A receptor, producing anxiolytic, hypnotic, and anticonvulsant effects.

Time Limit: 55 seconds
