Beta Blockers

Question 1

BB general uses (what do they treat?)

Answer 1

hypertension, anxiety, tremor, arrythmias

Question 2

What is the general net effect of BBs?

Answer 2

vasoconstricting

Question 3

What do BBs do in the body?

Answer 3

block B1 and B2 receptors
causing a decrease in HR, contractility, and renin release

Question 4

How do BBs help lower BP?

Answer 4

decrease of heart rate, decrease of force of contraction, decrease of renin release

Question 5

How do BBs help treat heart failure?

Answer 5

decreasing the heart rate gives the heart more time to relax instead of working too hard (restores HR variability, prevents arrhythmias, prevents/slows remodeling process)

Question 6

What is the net effect of BBs?

Answer 6

mixed net effect
increased preload, decreased contractility, increased afterload

Question 7

What does a BB do to cardiac output in heart failure?

Answer 7

Decreases it
(makes pt feel worse at first, but helps them live longer)

Question 8

What are side effects of beta blockers?

Answer 8

bronchospasm, heart failure, bradycardia, vasospasm, hyperglycemia, decreased LDL, depression, withdrawal syndrome

Question 9

Which beta blockers are cardio selective?

Answer 9

Metoprolol, atenolol
these are good to be used in pt with asthma (less pulmonary effect)

Question 10

Which BBs are nonselective?

Answer 10

propanolol

Question 11

Which BBs are vasodilating action?

Answer 11

Carvedilol, labetolol
