Definition

Atenolol

Class II antiarrhythmic that is a selective beta-1 blocker; decreases heart rate, blood pressure, and cardiac output. Used to treat supraventricular tachyarrhythmias, PVCs, hypertension, and cardiomyopathy

Captopril

ACE inhibitor used as a combined vasodilator to reduce afterload in heart failure patients. Trade name is Capoten

Digoxin

Cardiac glycoside derived from the foxglove plant; increases the strength of contraction and decreases hear rate. Used to treat CHF. Serum drug levels are monitored to help prevent toxicity

Diltiazem

Class IV antiarrhythmic that is a calcium channel blocker. Used to treat supraventricular tachyarrhythmias in dogs and cats and hypertrophic cardiomyopathy in cats. Trade name is Cardizem

Dobutamine

Synthetic inotropic agent with direct beta-1 adrenergic activity; increases cardiac output with very little tendency to produce arrhytthmias or increased heart rate. Administered by IV infusion

Dopamine

Precursor of norepinephrine that stimulates adrenergic receptors to produce increased heart contractility, increased heart rate, and increased blood pressure. Used to treat acute heart failure and oliguric renal failure

Epinephrine

Catecholamine that is the drug of choice for stimulating the heart after cardiac arrest. Also used for treatment of anaphylaxis. Stored in the refrigerator.

Furosemide

Loop diuretic that is the diuretic of choice for reducing edema associated with congestive heart failure. Trade name is Lasix

Hydralazine

Arteriolar dilator that works directly on smooth muscle in arterial walls to decrease afterload associated with CHF; trade name is Apresoline

Lidocaine

Class IB antiarrhythmic that is also a local anesthetic. Administered IV to treat PVCs and ventricular tachycardia; works by stabilizing cardiac cell membranes and decreasing automaticity

Nitroglycerin

Ointment used as a venodilator to improve cardiac output and reduce pulmonary edema. Used in horses as a leg sweat and a treatment for laminitis.

Prazosin

Combined vasodilator that blocks alpha-1 adrenoreceptors. Used as an adjunctive treatment of CHF, for dilated cardiomyopathy in dogs, systemic hypertension, and pulmonary hypertension. Trade name is Minipress.

Procainamide

Class IA antiarrhythmic used to treat PVCs and ventricular tachycardia; trade name is Pronestyl

Propranolol

Class II antiarrhythmic that is a nonselective beta-adrenergic blocker; reduces heart rate, cardiac output, and blood pressure. Used to treat hypertrophic cardiomyopathy, arrhythmias, and systemic hypertension in cats

Spironolactone

Potassium-sparing diuretic and aldosterone antagonist used as an adjunct diuretic with other medications to reduce edema associated with congestive heart failure.

Verapamil

Class IV antiarrhythmic that is a calcium channel blocker; used to treat supraventricular tachycardia, atrial flutter, and atrial fibrillation. Trade names are Calan or Isoptin.
