cardiovascular Flashcards
selective beta 1 adrenoreceptor antagonist
atenolol, metoprolol
clinical use of atenolol
angina
HTN
reduce CV mortality and risk of reinfarction in patients with acute MI
most common adverse effect of atenolol
fatigue / tiredness
atenolol + digoxin produces what effect?
additive bradycardia effect
atenolol + nitrates or antihypertensives produces what effect?
additive hypotensive effect
atenolol + dopamine will do what?
decrease effects of dopamine
contraindications of atenolol
ABCDE asthma block COPD DM hyperkalEmia
non selective Beta-adrenoreceptor antagonist
propranolol, timolol
beta -1 receptors specific to what tissue and are considered excitatory or inhibitory
postsynaptic sympathetic specific to cardiac, excitatory leading to increases in chronotropy, inotropy, dromotropy
beta -2 receptors specific to what tissue and are considered excitatory or inhibitory
postsynaptic sympathetic specific to all others (lungs), inhibitory leading to bronchodilation and vasodilation
clinical use of propranolol
angina HTN Post MI cardiomyopathy prevention of migraines
adverse effects of propranolol
2 BBs
- bradycardia, bronchospasm, sadness
- blood vessel spasm, blunted manifestations of hypoglycemia in diabetes, sexual dysfunction
2 BBs refers to what
mnemonic for adverse effects of propranolol
- bradycardia, bronchospasm, sadness
- blood vessel spasm, blunted manifestations of hypoglycemia in diabetes, sexual dysfunction
interactions of propranolol
additive bradycardia effect with digoxin
additive hypotensive effect with nitrates and antihypertensives
decrease effects of dopamine
risk of abrupt discontinuation of beta blockers
rebound HTN and tachycardia
interactions of atenolol
additive bradycardia effect with digoxin
additive hypotensive effect with nitrates and antihypertensives
decrease effects of dopamine
contraindications of propranolol
ABCDE asthma block COPD DM hyperkalEmia
non selective beta blocker used for elevated intraocular pressure
timolol
ACE inhibitors
lisinopril, ramipril
clinical use of lisinopril
HTN
CHF
tx and px diabetic nephropathy
improve 24 hour survival post MI
most common adverse effect of lisinopril
dizziness
drugs that act as vasodilators
ACE inhibitors
Ca++ channel blocker
alpha adrenergic agonist
angiotensin II antagonist
true or false, lisinopril may cause hypokalemia
false it is potassium sparring and my cause hyperkalemia
is there a significant risk of taking lisinopril during pregnancy
fetal renal failure
antacids + lisinopril
decreased serum levels with antacid
NSAIDS or salicylates + lisinopril
reduce antihypertensive effect
potassium sparing diuretics or trimethoprim + lisinopril
increase risk of hyperkalemia
insulin + lisinopril
increased risk of hypoglycemia
thiazide diuretic + lisinopril
increase hypotensive effect, nephrotoxic
angiotensin II does what to blood vessels
vasoconstricts
fatal symptom of lisinopril
angioedema
