dilates renal and mesenteric
positive intoropic but little effect on heart rate
diuretic
treats shock, renal failure, CHF |

|
Term
|
Definition
B1 ag
increase HR and contractility
CHF
tachycardia is major adverse effect |
|
|
Term
|
Definition
A1 ag
vasoconstrictor, decongestant, mydriatic, detumescent (reduces swelling)
reflex bradycardia is side effect |
|
|
Term
|
Definition
A2 ag
reduces sympathetic outflow to heart and causes vasodilation
hypertension, pain
causes bradycardia or rebound hypertension if withdrawn |

Definition
a1 blocker
little effect on bp
bph dudes can pee
abnormal 'jaculation
don't use'em wit vasodilators for ED--extreme hypotension |
|
|
Term
|
Definition
non-selective beta adrenergic blocker
competitive antagonist
don't use in diabetics or with (initial) heart failure, or with asthma
decreases heart rate and contractility
initial increase in peripheral resistance due to B2 block
B1-decrease renin release, promotes bronchoconstriction, inhibits glycolosis
Adverse: bradycardia, asthma aggravation, sexual dysfunction, fatigue |

B1 selective
hypertension, CHF, MI |

|
Term
| OTHER properties of beta blockers |
|
Definition
some block A1 too!
differences in lipid solubility
intrinsic sympathomimetic activity--only partial agonists--little effect on HR and CO
local anesthetic due to ion channel blockade
additional properties like vasodilation and antioxidant effects |
