Prostaglandins MCQs With Answer provide B. Pharm students a focused, application-oriented review of prostaglandin chemistry, biosynthesis, receptors, and pharmacology. This set emphasizes eicosanoid pathways, cyclooxygenase (COX) isoforms, PGE2, PGD2, PGF2α, and thromboxanes, linking molecular synthesis to physiological roles in inflammation, pain, fever, reproduction, and cardiovascular function. Questions cover mechanisms of action, receptor subtypes, synthesis inhibitors, … Read more

Introduction: Serotonin (5-HT) is a key neurotransmitter involved in mood, gastrointestinal motility, nausea, vascular tone and platelet function. Understanding 5-HT receptor subtypes (5-HT1, 5-HT2, 5-HT3, 5-HT4), synthesis, metabolism and pharmacokinetics is essential for B.Pharm students studying pharmacology. 5-HT antagonists—such as ondansetron, granisetron, ketanserin, cyproheptadine and alosetron—are clinically important for antiemetic, antipsychotic adjunct, antimigraine and IBS … Read more

Histamine and its antagonists MCQs With Answer Histamine is a key bioamine in pharmacology controlling allergy, gastric acid secretion and central neurotransmission. B.Pharm students must master histamine receptors (H1, H2, H3, H4), synthesis by L‑histidine decarboxylase, metabolism via diamine oxidase and HNMT, and the pharmacology of H1 and H2 antagonists. This introduction links mechanism of … Read more

Introduction Autacoids are locally acting biologically active substances that modulate vascular tone, inflammation, bronchial reactivity and platelet function. This concise guide focuses on Classification of autacoids MCQs With Answer for B. Pharm students, covering major groups — eicosanoids (prostaglandins, thromboxanes, leukotrienes), biogenic amines (histamine, serotonin), kinins (bradykinin), nitric oxide and related mediators. Emphasis is placed … Read more

Introduction: Autacoids are locally produced bioactive mediators — such as histamine, serotonin (5‑HT), prostaglandins, leukotrienes, bradykinin and nitric oxide — that regulate vascular tone, inflammation, pain, allergy and homeostasis. For B. Pharm students, understanding autacoid synthesis, receptor subtypes (H1–H4, 5‑HT families, prostanoid and leukotriene receptors), metabolic pathways (MAO, COMT, DAO, 5‑LOX, COX) and clinically relevant … Read more

Pharmacology of antidiuretics explores drugs that mimic or block antidiuretic hormone (ADH/vasopressin) action—key for water balance, plasma osmolality, and blood pressure regulation. This concise guide for B. Pharm students covers mechanisms (V1 vs V2 receptors), intracellular signaling (cAMP, aquaporin-2 insertion), major agents (desmopressin, vasopressin, conivaptan, tolvaptan), clinical uses (central diabetes insipidus, von Willebrand disease, SIADH), … Read more

Introduction The pharmacology of diuretics is a core topic for B. Pharm students, covering drug classes such as loop diuretics, thiazides, potassium-sparing agents, carbonic anhydrase inhibitors and osmotic diuretics. This topic explores mechanisms of action in specific nephron segments, pharmacokinetics, indications (hypertension, edema, heart failure, renal disease), adverse effects (electrolyte disturbances, metabolic alkalosis/acidosis, hyperuricemia), and … Read more

This concise, exam-focused review on Plasma volume expanders MCQs With Answer helps B. Pharm students master pharmacology, formulation, and clinical use of crystalloids and colloids. Topics include mechanisms of action, oncotic versus osmotic effects, common agents (normal saline, Ringer’s lactate, albumin, gelatin, dextrans, hydroxyethyl starch), indications, dosing, adverse effects, monitoring, pharmacokinetics, compatibility, and regulatory issues. … Read more

Antiplatelet drugs MCQs With Answer are essential for B. Pharm students to master pharmacology of antiplatelet agents, mechanisms, clinical uses, dosing, adverse effects and drug interactions. This focused set covers aspirin, P2Y12 inhibitors (clopidogrel, prasugrel, ticagrelor, cangrelor), glycoprotein IIb/IIIa inhibitors, PDE inhibitors (cilostazol, dipyridamole) and newer agents like vorapaxar. Questions emphasize mechanism of action, prodrug … Read more

Fibrinolytic drugs (thrombolytics) are critical agents that dissolve intravascular clots by converting plasminogen into plasmin. B.Pharm students should grasp mechanisms of action, fibrin specificity, pharmacokinetics, major agents (streptokinase, urokinase, alteplase/tPA, reteplase, tenecteplase), clinical indications (acute MI, pulmonary embolism, ischemic stroke), contraindications, adverse effects like bleeding and antigenicity, monitoring parameters (fibrinogen, D‑dimer), and reversal strategies (aminocaproic … Read more
