Brand questions use only name pairings verified against the linked product source. Unverified pairings are withheld from these questions; the other study content remains available.
Label date: 20260717 · For learning, not clinical decisions. US label and brand information; always consult the current source.
Source snapshot checked: 2026-10-21. The source document and selected fields were compared. The complete card has not had an independent clinical review.
Mechanism: Inhibits calcium influx, dilating coronary arteries and arterioles and inhibiting coronary artery spasm.
On both cards: Common side effects — Edema; Flushing; Palpitations
Only on the Nifedipine card: Used for — Vasospastic angina meeting the specified diagnostic criteria or with a suspected vasospastic component; Chronic stable angina despite adequate beta-blocker and/or nitrate treatment, or when those agents cannot be tolerated; Hypertension, for the cited extended-release tablets · Common side effects — Headache; Asthenia · Warnings — Hypersensitivity to nifedipine (contraindicated) · Interactions — Beta blockers: reports of increased heart failure, severe hypotension or worsening angina with the combination; Long-acting nitrates: the label permits coadministration, but controlled studies of the combination’s antianginal efficacy are lacking
Mechanism: Olmesartan blocks angiotensin II effects, amlodipine blocks calcium entry into vascular smooth muscle, and HCTZ promotes sodium and chloride excretion.
On both cards: Common side effects — Dizziness
Only on the Olmesartan / Amlodipine / Hydrochlorothiazide card: Used for — Hypertension requiring the selected olmesartan/amlodipine/hydrochlorothiazide combination; not indicated for initial therapy · Common side effects — Peripheral edema; Headache; Fatigue; Muscle spasms · Warnings — Hypotension in volume-depleted patients; Fluid and electrolyte imbalance; Sprue-like enteropathy · Interactions — NSAIDs; Lithium; Aliskiren (in diabetes)
Mechanism: Benazepril inhibits ACE, lowering angiotensin II and aldosterone; amlodipine is a dihydropyridine calcium channel blocker.
On both cards: Common side effects — Edema
Only on the Amlodipine / Benazepril card: Used for — Hypertension not controlled on monotherapy · Common side effects — Cough · Warnings — Angioedema / anaphylactoid reactions; Hypotension and hyperkalemia; Contraindicated with neprilysin inhibitors · Interactions — Potassium supplements / K-sparing diuretics; Lithium; NSAIDs
An item counts as shared only when both cards use the same wording. If a card does not list an item, that is not a statement that the effect never occurs.
