NSG 233 Adult Health III

Module 5

Beta Blockers

-lols

Beta blockers:

 Beta adrenergic blockage in the myocardium and in the electrical

conduction system of the heart

 Decrease heart rate (chronotropic action)

 Decrease myocardial contractility (inotropic [force] action)

 Decrease rate of conduction through the AV node

 Used for primary HTN

 Used for angina, tachydysrhythmias, heart failure, and MI

 Migraine, stage fright, glaucoma

 Metoprolol (Lopressor)

 Atenolol (Tenormin)

 Metoprolol (Toprol XL)

 Labetalol (Normodyne)

 Propranolol (Inderal)

 Can cause

a. Bradycardia

b. Decreased cardiac output

c. AV block

d. Orthostatic hypotension

e. Rebound myocardium excitation

f. Bronchoconstriction: use with caution in patients with asthma

g. Inhibits glycogenolysis

 Contraindicated in AV block and sinus bradycardia

 Contraindicated in patients with asthma, bronchospasm, and heart failure
