HTN Practice Pt2 Flashcards
amlodipine
norvasc -dhp ccb
nifedipine er
procardia - dhp ccb
diltiazem
cardizem - non dhp ccb
aliskiren
tekturna - diirect renin inhibitor
bisoprolol
zebata - cardioselective beta blockers (beta 1)
metoprolol succinate
toprol - cardioselective beta blocker (beta 1)
carvedilol
coreg - alpha/beta blocker (beta 1 and 2, alpha 1)
dhp ccb moa
inhibits calcium ions from entering slow channels of vascular smooth muscle- leading to vasodilation
dhp ccb contraindications
none
dhp ccb adr
peripheral edema, pulmonary edema, hepatotoxicity, thrombocytopenia
dhp ccb ddi
major substrate of CYP3A4
dhp ccb notes
immediate release nifedipine has increased risk of mi and mortality- only er is used, can take up to one week to see bp lowering effects- no electrolyte changes, major substrate of cyp3a4
non dhp ccb moa
inhibits calcium from entering vascular smooth muscle and myocardium, slowing av node/hr
non dhp ccb contraindications
2nd or 3rd degree heart block
non dhp ccb adr
peripheral edema, pulmonary ede3ma, ha, heart failure, heart block, hepatotoxicity
non dhp ccb ddi
major substrate of CYP3A4, moderate inhibitor of CYP3A4- worse with verapamil than dilt
non dhp ccb notes
cyp3a4 major substrate and moderate inhibitor (dose adjustments for lovastatin/simvastatin), avoid use in patients with hfref, avoid routine use with beta blockers, multiple brands exist, following timing for administration (dilt only), some brands are capsules that can be opened and sprinkled on food (dilt only)
amlodipine dosing
norvasc is normally dosed at 2.5-10 mg daily
nifedipine er dosing
procardia is dosed at 30-120 mg daily
diltiazem dosing
cardizem is dosed at 120-360 mg daily
beta blocker moa
inhibiting beta 1 (all) and beta2(some) to decrease hr and myocardial contractility- variable inhibition based on selectivity
beta blocker contraindication
severe bradycardia
precaution: with copd disease
beta blocker adr
dizziness, fatigue, reduced exercise tolerance, bronchospasm, insomnia, impotence
beta blocker ddi
additive av nodal blockage with non dhp ccb
beta blocker notes
avoid abrupt withdrawal- can cause rebound tachycardia, angina, and mi, patients may feel fatigued when starting- this will go away with time, may mask feelings of low blood glucose, use with caution in patients with severe bronchospastic disease, can enhance hypoglycemic effects of insulin and sulfonylureas
bisoprolol dosing
zebata is usually dosed at 2.5-10mg daily
cardioselective
metoprolol succinate dosing
toprol xl is dosed at 50-200 mg daily
cardioselective
carvedilol dosing
coreg is dosed at 12.5-50 mg in 2 divded doses
combined alpha and beta selectivity
direct renin inhibitor notes
do not use raas drugs in combination., long half life, lack of long term studies on cv outcomes, high drug costs, electrolyte impact
aliskiren dosing
tekturna is dosed at 150-300 mg daily
