timolol
beta-blocker
doxazosin
alpha1 blocker
prazosin
alph1 blocker
terazosin
alpha1 blocker
clonidine
central acting sympatholytic
guanabenz
central acting sympatholytic
guanfacine
central acting sympatholytic
methyldopa
central acting sympatholytic
alpha1
vasculature
beta1
cardiac
catecholamine
from adrenal medulla
-affect tone of resistance in vessels as well as HR and output
beta1 selective blocker
metoprolol and atenolol
non-selective beta blocker
propanolol
ISA
intrinsic sympathomimmetic activity
- low sympathetic tone - agonist
- high sympathetic tone - antagonist
carvedilol and labetalol
alpha and beta blockers
nadolol
non-selective beta blocker
-contraindicated in asthma
beta2 bronchodilation
non-selective beta blockers
-relative contraindication
diabetes
don’t want non-selective beta blocker
beta-blockers
no longer first line treatment for HTN
-except when with heart failure, recent MI, or reduced left ventr. function
labetalol
selective alpha 1 blocker
non-selective beta 1 and 2 blocker
partial agoninst at beta 2
- IV for severe HTN
- acceptable for HTN during pregnancy
carvedilol
non-selective beta-blocker and alpha-1 blocker
also antioxidant
nebivolol
beta1 selective blocker
- also decreases TPR and BP
- via increased nitric oxide formation
phenylephrine
alpha agonist
alpha 1 > alpha 2
beta blockers with vasodilator activity
non-selective - carteolol, carvedilol, labetalol
beta-1 selective - betaxolol, nebivolol
ex/ nebivolol - increases NO
esmolol
beta1 selective
-very rapid onset and short duration of action
IV for peri-op tachycardia and HTN, hypertensive emergencies, arrhythmias
also used in electroconvulsive therapy
aka brevibloc
prazosin
alpha-1 selective blocker
-no loss of alpha2 inhibition on NE release
admin of phenylephrine - no effect
phentolamine
non-selective alpha blocker
- decreased alpha 2 inhibitor
- therefore larger increase of NE release
men with HTN and BPH
alpha-1 selective blocker
-prazosin
clonidine receptor agonist
clonidine
clonidine
alpha 2 receptor agonist
-central acting
increased BP, then decreased BP**
sudden withdrawal - hypertensive crisis
dangerous effect on fetus
ACE (-)
-ends in pril
methyldopa
converted to methyl-NE
-stored in NE vesicles
central alpha2 agonist
- decreased sympathetic outflow
- decreased BP
-treat HTN in pregnancy***
aka aldomet
hypertensive emergency
involves organ damage
drugs given IV
renoprotective
ACE (-) or ARBs
no used unless specific indication
beta-blockers
african descent
ARB and ACE (-) worse
