Cardiac Medications ๐โค๏ธ
This visual neatly organizes three of the most essential cardiac drug classes: Calcium Channel Blockers (CCBs), Beta Blockers (BBs), and ACE Inhibitors (ACEIs) โ each playing a unique role in keeping the heartโs rhythm and pressure in check.
๐น Calcium Channel Blockers (Amlodipine, Diltiazem, Verapamil)
Think of these as the โmuscle relaxersโ for your heart and vessels. They work by relaxing the smooth muscles in blood vessels, helping blood flow more easily โ perfect for hypertension, angina, and arrhythmias.
โ ๏ธ Side effects: Constipation, headache, and peripheral edema.
๐ก Nursing note: Avoid grapefruit juice (it boosts drug levels dangerously!) and remind patients about good oral hygiene โ these drugs can cause gingival hyperplasia.
๐ธ Beta Blockers (Metoprolol, Atenolol, Carvedilol)
These are your heartโs โbrakes.โ They slow down heart rate and decrease the force of contraction โ ideal for hypertension, heart failure, and arrhythmias.
โ ๏ธ Side effects: Bradycardia, fatigue, and bronchospasm.
๐ก Nursing note: Always monitor heart rate and blood pressure before giving the dose. In diabetic patients, beta blockers can mask hypoglycemia symptoms โ teach them to monitor glucose closely!
๐ก ACE Inhibitors (Lisinopril, Enalapril, Ramipril)
These drugs are the โprotectorsโ โ they block the conversion of angiotensin I to angiotensin II, reducing vasoconstriction and easing the heartโs workload. Commonly used for hypertension, heart failure, and diabetic nephropathy.
โ ๏ธ Side effects: Dry cough, angioedema, and hyperkalemia.
๐ก Nursing note: Check renal function and potassium levels, especially when starting or adjusting doses. Strictly avoid in pregnancy โ these can cause fetal harm.
๐ฌ In short:
CCBs = relax the heart and vessels ๐ซ
BBs = slow the heart ๐
ACEIs = protect the heart and kidneys ๐ง
