Difficulty: EasyCardiovascular System

Match each commonly prescribed cardiovascular medication with its classic clinical adverse effect profile.

  • AmiodaroneThyroid dysfunction and pulmonary interstitial infiltrates
  • LisinoprilBradykinin-mediated dry cough and facial swelling
  • AmlodipineDose-dependent peripheral edema without pulmonary congestion
  • SpironolactonePainful breast enlargement and hyperkalemia

Answer

Amiodarone pairs with thyroid/pulmonary toxicity; Lisinopril pairs with dry cough/angioedema; Amlodipine pairs with peripheral edema; Spironolactone pairs with gynecomastia/hyperkalemia.
Each medication has a unique, high-yield mechanism of toxicity commonly tested: Amiodarone (iodine-rich, tissue deposition), Lisinopril (bradykinin accumulation), Amlodipine (precapillary vasodilation), and Spironolactone (anti-androgen cross-reactivity).

Step-by-Step Solution

1
Evaluate Amiodarone's mechanism and chemical composition.
Identify that its high iodine content and tissue deposition characteristics lead directly to thyroid abnormalities and pulmonary toxicities.
Recognizing unique drug structures helps predict specific long-term end-organ damage.
2
Evaluate Lisinopril's effect on kinin degradation pathways.
Identify that ACE inhibition prevents bradykinin breakdown, identifying the cause of cough and angioedema.
Understanding the secondary metabolic pathways of ACE explains its most common and potentially dangerous non-renal side effects.
3
Evaluate Amlodipine's hemodynamic effects at the capillary level.
Identify that selective precapillary vasodilation causes fluid extravasation into peripheral tissues.
Differentiating vasodilation-induced edema from clinical heart failure is a critical patient management skill.
4
Evaluate Spironolactone's structural receptor affinities.
Identify that it antagonizes androgen receptors in addition to sparing potassium.
Steroid-derivative diuretics often have cross-reactivity with sex hormone receptors.
