Cardiovascular

Drugs acting on the heart, vessels, blood pressure and clotting. Seven classes you'll administer and monitor constantly on any med-surg or telemetry floor.

13 drug classes 47 key drugs

Beta-Blockers

-olol High-yield

Slow heart rate & lower BP by blocking β-adrenergic receptors. Watch for bradycardia.

ACE Inhibitors

-pril High-yield

Lower BP by blocking angiotensin conversion. Classic dry cough & angioedema risk.

Statins

-statin

Lower LDL cholesterol via HMG-CoA reductase inhibition. Monitor for myopathy.

Anticoagulants

High-yield Bleed risk

Prevent clot formation. High-alert medications — bleeding precautions essential.

Calcium Channel Blockers

-dipine

Relax vessels (dihydropyridines) or slow the heart (non-dihydropyridines). Watch edema & bradycardia.

Diuretics

High-yield

Offload fluid via the kidney — loop, thiazide & potassium-sparing. Monitor electrolytes closely.

Antiarrhythmics

High-yield

Restore & maintain normal rhythm across the four Vaughan-Williams classes. All can be proarrhythmic.

Cardiac Glycosides (Digoxin)

High-yield

Strengthen and slow the heart in HF and atrial fibrillation. Narrow therapeutic index — a high-alert drug.

Nitrates

High-yield

Vasodilators that relieve angina by cutting cardiac workload. Never combine with PDE5 inhibitors.

ARBs

-sartan High-yield

Block the angiotensin II receptor — the ACE-inhibitor alternative without the cough. Recognizable by -sartan.

Antiplatelets

High-yield

Stop platelets from clumping — the arterial-clot drugs. Distinct from anticoagulants; do not stop after a stent.

Vasopressors & Inotropes

High-yield

Adrenergic drugs that raise blood pressure and cardiac output in shock. High-alert ICU titration.

Other Antihypertensives

Alpha-blockers, central alpha-2 agonists, and direct vasodilators — the add-on/resistant-HTN agents.
