Indications
Hypertension, angina pectoris, prophylaxis for myocardial reinfarction, reduce cardiovascular mortality in hemodynamic patients with acute myocardial infarction, prophylaxis of migraine syndromes, prophylaxis of paroxysmal tachycardia, prior to cardiac catheterisation.
Contra-Indications
2nd or 3rd degree AV block, sinus bradycardia, sick sinus syndrome, severe peripheral arterial disease, Printzmetal’s angina, uncompensated cardiac failure (except carvedilol), cardiogenic shock, hypotension, right ventricular failure secondary to pulmonary hypertension, significant cardiomegaly, untreated phaeochromocytoma, metabolic acidosis. Non-cardioselective β-blockers (nadolol, oxprenolol, penbutolol, pindolol, propranolol, timolol) are also generally contraindicated in patients with obstructive airways disease or a history of bronchospasm.
Special Precautions
Poor cardiac reserve should be controlled with digitalis and diuretics. History of bronchospasm (cardioselective β-blockers e.g. acebutolol, atenolol, betaxolol, bisoprolol, celiprolol, metoprolol, nebivolol usually have a lesser effect on airways resistance than the non-selective type but their use should also be avoided in patients with wheezing or obstructive airway disease unless there are compelling clinical reasons). Diabetes. Asthenic symptoms. Cerebrovascular insufficiency. Atopy. Renal or hepatic impairment, thyrotoxic crisis. General anaesthesia; consider withdrawal before elective surgery. Pregnancy, lactation. Withdraw gradually.
Side Effects
Cold extremities, CNS and sleep disturbances (particularly with the more lipophilic drugs), bradycardia (less with carvedilol, pindolol), exertional tiredness, bronchospasm, heart failure, hypotension, GI upset, alopecia, thrombocytopenia. Withdraw gradually in unexplained dry eyes or skin rash.
Drug interactions
Verapamil, diltiazem, class I antiarrhythmics, amiodarone, cardiac depressant anesthetics, cardiac glycosides. Oral hypoglycemics, insulin, reserpine, ergot alkaloids. Cimetidien (with labetalol and propranolol only), indomethacin (possibly other NSAIDs), clonidine. Thyroxine, liver enzyme inducers (e.g. rifampicin, barbiturates), β-agonists, direct and indirect sympathomimetic amines, fluvoxamine, phenothiazines, propafenone.
