cardio drugs Flashcards
ACEi EX
ramipril / lisinopril
ACEi IN
HTN
HF
MI 2nd prevention
ACEi MA
inhibit angiotensin converting enzyme (ACE)
(reduces sodium + water retention / arterial + venous dilation)
ACEi CC
afro-caribbeans
lowers glucose in diabetes
NO in pregnancy
ACEi SA
persistent dry cough
renal dys
angioedema
amiodarone IN
arrhythmias
(AFib / flutter
VFib / pulseless VTACH)
amiodarone MA
(CLASS 3) block K+ channels -> increase refrac period
(slows HR + AV conductions, prolongs QT)
amiodarone CC
heart block, brady, thyroid dys, hypokalaemia NO
avoid IV in cardiomyopathy, HF, sever resp failure
amiodarone SA
hypokalaemia
corneal microdeposits
hepatic disorders
hyperthyroidism
resp disorders
skin reactions (phototoxic)
atropine IN
bradycardia
atropine MA
inhibits M3 receptors -> anticholinergic effects
atropine CC
GI obstruction
acute MI
arrhythmias
tachycardia
HF
CAD
HTN
hyperthyroidism
atropine SA
dry mouth
dizziness
blurred vision
nausea
aspirin IN
antiplatelet agent
ACS
ischaemic stroke
thromboprophylaxis in CVD risk
aspirin MA
COX inhibitor
inhibits TXA2 synth (aggregates platelets) + prostaglandin production (activation)
aspirin CC
active peptic ulceration
bleeding disorders
aspirin SA
GI bleeding + ulceration
ARBs EX
losartan / valsartan
ARBs IN
HTN
post MI
HF
ARBs MA
inhibits binding of angiotensin-ll
(vasodilation + aldosterone blockage)
ARBs CC
pregnancy / planning to be
ARBs SA
dizziness
hyperkalaemia
localised angioedema
a blockers EX
doxazosin
a blockers IN
resistant HTN
a blockers MA
block a adrenoreceptors
(vasodilation)
a blockers CC
history of postural hypotension
a blockers SA
dizziness
hyperkalaemia
localised angioedema
B blockers EX
cardioselective -
atenolol / bisoprolol
non-selective -
propranolol / carvedilol
B blockers IN
cadioselective -
angina
ACS
HTN
HF
non-selective -
hyperthyroidism
migraine
B blockers MA
(CLASS 2) competitive inhibition of B1 / B2 adrenoreceptors
(lowers HR and BP)
B blockers CC
‘brittle’ asthma
worsen HF in short term
B blockers SA
tiredness
cold peripheries
CCBs EX
dihydropyridines -
amlodipine
rate limiting CCBs -
verapamil / diltiazem
CCBs IN
dihydropyridines -
HTN
angina
rate limiting CCBs -
HTN
angina
SVT (slows HR)
CCBs MA
(CLASS 4) block calcium channels
CCBs CC
on B blockers
CCBs SA
dizziness
flushing
headache
nausea
ankle oedema (dihydropyridines)
clopidogrel IN
thromboprophylaxis (aspirin intolerance)
ACS (+ aspirin)
clopidogrel MA
inhibits P2Y12 receptors (platelet aggregation)
clopidogrel CC
risk of bleeding
clopidogel SA
GI bleeding + ulceration
digoxin IN
HF
arrhythmias
HTN
digoxin MA
inhibits Na-K-ATPase pump -> increase in intracellular Ca2+
(decreases AVN conduction)
digoxin CC
narrow therapeutic index!
too much = AV delay -> brady / AVB
increases vent irritability = vent arrhythmias
overdose = toxicity (N+V, headache, yellow vision)
digoxin SA
AVB
arrhythmias
N+V
diarrhoea
colour vision disturbances
diuretics EX
thiazide -
bendrofluazide
loop -
furosemide
