Welcome to your 2. 💊 Inflammatory Mediators & Anti-Inflammatory Pharmacology Arena
1.
A patient with allergic airway inflammation has mast-cell activation with release of a prostanoid that contributes to bronchial narrowing. Which mediator is most closely associated with this response?
2.
A 30-year-old woman is prescribed misoprostol. Which pairing best reflects two clinically useful actions of this drug?
3.
A patient takes a large paracetamol overdose. Initially, most hepatic conjugation pathways become saturated. Which subsequent event most directly produces liver injury?
4.
A 55-year-old man with chronic inflammatory joint disease is switched from a non-selective NSAID to a selective COX-2 inhibitor. His gastrointestinal symptoms improve, but the physician explains that one important risk remains. Which adverse effect still requires attention?
5.
A 35-year-old woman with dysmenorrhea obtains good pain relief from ibuprofen. The drug reduces pain mainly because it decreases formation of mediators that sensitize peripheral nociceptors. Which pharmacodynamic consequence is responsible?
6.
A 46-year-old woman with chronic inflammatory pain is prescribed piroxicam. Compared with ibuprofen, she requires less frequent dosing. Which pharmacokinetic feature best explains this difference?
7.
A 60-year-old man with ischemic heart disease is being considered for treatment with a selective COX-2 inhibitor. The physician is concerned that vascular prostacyclin may be reduced while platelet thromboxane formation remains relatively preserved. Which complication may result from this imbalance?
8.
A patient with rheumatoid arthritis is receiving an NSAID that reduces pain and swelling but continues to develop progressive joint damage. Which additional drug category is intended to modify the underlying course of the inflammatory disease?
9.
A newborn has a congenital cardiac lesion in which systemic circulation temporarily depends on continued patency of the ductus arteriosus. Which prostaglandin-related action is therapeutically useful?
10.
A physician compares ibuprofen with piroxicam for two patients requiring NSAID therapy. One patient needs short-term symptom control, while the other requires prolonged action with less frequent administration. Which matching is most appropriate?
11.
A 21-year-old man develops redness and warmth around an inflamed joint. Which prostaglandin-related vascular effect contributes most directly to these findings?
12.
A patient receiving a prostaglandin-related drug for gastric mucosal protection benefits from reduced acid secretion and enhanced defensive mechanisms. Which additional effect contributes most to mucosal protection?
13.
A student compares prostacyclin and thromboxane A₂ in vascular homeostasis. Which statement best describes their physiological relationship?
14.
A 66-year-old man with chronic inflammatory joint pain has a history of cardiovascular disease and previous gastric ulceration. The physician considers a selective COX-2 inhibitor because of its gastrointestinal advantage but remains cautious. Which interpretation best reflects the pharmacological reasoning?
15.
A 58-year-old man with inflammatory arthritis has persistent joint pain despite simple analgesics. He also has a previous history of peptic ulcer disease. The physician wants an anti-inflammatory drug with less inhibition of gastric mucosal protective prostaglandins. Which drug class is most appropriate?
16.
A drug selectively suppresses prostacyclin production in vascular endothelial cells while leaving platelet thromboxane synthesis intact. Which change would most likely occur?
17.
A researcher compares prostaglandin effects in two tissues. The same mediator causes relaxation in one tissue but contraction in another. Which explanation best accounts for this difference?
18.
A student is asked to explain why inhibition of cyclooxygenase can simultaneously reduce pain and fever. Which sequence best explains this relationship?
19.
A vascular endothelial cell synthesizes a prostanoid that increases cyclic AMP in platelets. Which functional consequence is expected?
20.
A 54-year-old man with inflammatory arthritis has previously developed troublesome gastrointestinal symptoms with conventional NSAIDs. He is prescribed celecoxib. Which statement best describes the trade-off associated with this drug?
21.
A patient with pulmonary arterial hypertension receives a prostacyclin-related therapy. Which combination of effects provides the strongest rationale for its use?
22.
A 27-year-old woman at term requires pharmacological cervical ripening before induction of labor. Which action best explains the effectiveness of the selected prostaglandin preparation?
23.
A 64-year-old man taking low-dose aspirin for secondary prevention of arterial thrombosis stops the drug before a planned procedure. Although aspirin is rapidly cleared from plasma, its antiplatelet effect persists for several days. Which property best explains this finding?
24.
A 27-year-old woman takes repeated therapeutic doses of aspirin for fever and musculoskeletal pain. She asks why a considerably lower dose is used when aspirin is prescribed for prevention of platelet aggregation. Which explanation is most appropriate?
25.
A 70-year-old woman with osteoarthritis and reduced renal perfusion starts a non-selective NSAID. A few days later she develops edema and a rise in serum creatinine. Which pharmacological effect most directly contributed to this complication?
26.
A 48-year-old man uses an NSAID for chronic inflammatory pain. He develops epigastric discomfort and occult gastrointestinal blood loss. Which physiological function has most likely been impaired?
27.
A 63-year-old patient with reduced renal perfusion depends on locally produced prostaglandins to help maintain renal blood flow. Which effect is most relevant in this setting?
28.
A 24-year-old man presents shortly after a potentially toxic ingestion of paracetamol. N-acetylcysteine is started promptly. Which action best explains its protective effect?
29.
A 19-year-old woman presents several hours after ingesting a large quantity of aspirin. She is tachypneic and later develops metabolic acidosis. Intravenous sodium bicarbonate is administered. What is the main purpose of alkalinizing the urine?
30.
A 32-year-old woman with severe uterine atony after delivery requires a prostaglandin analogue with a strong uterotonic effect. Which drug best matches this therapeutic need?
31.
A 42-year-old patient takes paracetamol for fever and musculoskeletal discomfort. Compared with a conventional NSAID, the drug produces little reduction in peripheral inflammatory swelling. Which feature best explains this difference?
32.
A prostaglandin binds to a membrane receptor and subsequently alters intracellular cyclic AMP concentration. Which receptor category is most consistent with this mechanism?
33.
A 30-year-old woman has taken a large amount of paracetamol but feels relatively well during the early period after ingestion. Laboratory monitoring is arranged because severe toxicity can still develop. Which organ is the principal site of serious injury?
34.
A patient with severe salicylate poisoning develops confusion, worsening acidemia and renal impairment despite supportive treatment. Which intervention is most appropriate for rapid removal of the toxic substance?
35.
A 32-year-old woman with fever and headache requires an analgesic-antipyretic but has a condition in which significant platelet inhibition is undesirable. Which drug best fits this requirement?
36.
A patient develops an inflammatory response in which local PGE₂ production rises. Which combination of findings is most consistent with this mediator’s effects?
37.
A patient with inflammation develops fever. Cytokine signaling increases prostaglandin formation in the hypothalamic region. Which subsequent event is most directly responsible for the rise in body temperature?
38.
A patient with glaucoma is treated with a PGF₂α analogue. Which physiological change most directly lowers intraocular pressure?
39.
A platelet at the site of vascular injury releases a prostanoid that favors hemostasis. Which combined effect is most characteristic of this mediator?
40.
A 58-year-old man with an acute inflammatory condition has marked pain at the affected site despite only modest tissue injury. Which prostaglandin-mediated mechanism best explains the disproportionate pain?
