Contraindications Flashcards
Beta blockers avoid
In asthma due to effects on B2, cause bronchospasms (metoprolol & atenolol are B1 selective still don’t use)
Beta blockers can cause
HF
Beta blockers worsen
Heart block, reduces exercise tolerance, exertion dyspnoea, fatigue, hypotension, bradycardia
Beta blockers inhibit
Lipoprotein lipase - worsen lipid profile
Beta blockers CNS effects
Nighmeres
Alpha 1 blockers
Postural hypotension, depression, drowsiness, nasal stuffiness, increases GI motility (diarrhoea), urinalysis incontinence
Alpha 2 agonist
-C & -I effects may promote HF
ACE inhibitors related to bradykinin increase
Persistent dry cough, and rarely angioedema
ACE inhibitor
Initial hypotension, rash, dysgeusia, foetal abnormalities.
Exacerbates impairment in bilateral renal artery stenosis
ACE inhibitors caution
Concurrent use with diuretics and NSAIDS
Angiotensin receptor blocker
Usually well tolerated but hypotension, dizzy, rash
Angiotensin receptor blocker GI
Nausea, vomit, diarrhoea, hyperkalaemia, renal issues if bilateral renal artery stenosis, teratogenic
Statins
Myopathy and rhambdomyolysis (breakdown of muscle fibres releasing myoglobin to plasma and eventually kidneys)
Statins teratogen
Inhibiting cholesterol formation can affect developmental genes, avoid in pregnancy
Statins increased chances of adverse effects
High dose in elderly, and drug interactions
Fibrates GI
GI-related effects are minor and are resolved with withdrawal
