Q

Alpha agonist indications

A

topical for nasal congestion and HTN tx

17
Q

prolonged vasoconstriction leads to hypoxia which causes vasodilation and ultimately ___.

A

reactive hyperemia

18
Q

indications for beta agonists

A

severe CHF, cardiac shock, asthma, premature labor

19
Q

alpha blocker indications

A

HTN, BPH

20
Q

beta blocker indications

A

HTN, hyperthyroid, benign tremors, afib

21
Q

do not use beta blockers in these 4 cases

A
  1. asthma, 2. avoid sudden withdrawl in arrhythmias, 3. uncompensated CHF, 4. bradycardia
22
Q

Receptors are blocked, the target cells in myocardium tend to produce more receptors d/t them not getting enough of the drug they need

A

Why is there an increased risk of cardiac arhythmias with abrupt beta blocker withdrawl?
