Pharmacology High-Yield One-Liners
A rapid-revision capsule containing high-yield pharmacological one-liners, classic drug associations, and exam pearls frequently tested in university and competitive entrance exams.
Welcome to Bright Medico’s Rapid Revision series. Pharmacology requires memorizing numerous drug names, mechanisms, toxicities, and antidotes. This article compiles Pharmacology High-Yield One-Liners frequently tested in professional university exams and competitive tests for MBBS, nursing, pharmacy, dental, and physiotherapy students.
Direct Answer & Key Points
For quick recall during your studies, review these essential high-yield points and rapid-revision associations:
- Atropine: Specific antidote for organophosphate poisoning, reversing muscarinic overactivation.
- Methotrexate Toxicity: Reversed by Leucovorin (Folinic acid) rescue.
- Torsades de Pointes: Symptomatic Torsades de Pointes induced by antiarrhythmics is managed with intravenous Magnesium Sulfate.
- Heparin-Induced Thrombocytopenia (HIT): Treated by switching to direct thrombin inhibitors like Argatroban.
- Anaphylaxis: Drug of choice is Adrenaline (Epinephrine) IM.
- Cranial Diabetes Insipidus: Treated with Desmopressin.
- Malignant Hyperthermia: Antidote is Dantrolene.
- Red Man Syndrome: Caused by rapid intravenous infusion of Vancomycin.
Essential Antidotes & Associations
- Paracetamol: N-acetylcysteine replenishes glutathione stores in the liver.
- Opioids: Naloxone acts as a competitive antagonist at mu-opioid receptors.
- Iron Overdose: Deferoxamine binds free iron to form a chelated complex excreted in urine.
- Malignant Hyperthermia: Dantrolene blocks ryanodine receptors (RyR1) to decrease calcium release in skeletal muscle.
Remember This: Exam Pearl
Always remember that Heparin inhibits factor Xa and thrombin via Antithrombin III, monitored by aPTT, whereas Warfarin inhibits Vitamin K epoxide reductase, monitored by PT/INR.
