Cardiac Medications

Cardiac Medications and their effects

Nitrates (nitroglycerin) Decrease proload through peripheral vasodilation, reduce myocardial oxygen demand, reduce angina, may also dilate coronary arteries, improve coronary blood flow.
Beta-adrenergic agents (Propranolol) Reduce myocardial oxygen demand by reducing HR and contractility; control arrhythmias, chest pain, reduce BP
Calcium channel blockers (Cardizem, Procardia) Decrease HR, decrease contractility, dilate coronary arteries, reduce BP, chest pain, control arrhythmias
Antiarrhythmias (four main drugs, ex: Quinidine, Procainamide) Alter conductivity, restore normal heart rhythm, control arrhythmias, improve CO
Antihypertensives (four main class, ex: Propranolol) Control HTN, maintain DBP < 90 mmHg, decrease afterload, reduce myocardial oxygen demand
Digitalis Decrease HR, Increase contractility, Main treatment in CHF
Diuretics (ex: Lasix) Decrease proload and afterload, control HTN
Aspirin May prevent MI
