Chỉ định và Liều dùng
Emergency treatment of cardiac arrhythmias
Adult: 2.5 mg injected at a rate of 1 mg/minute, may repeat every 5 minutes if needed. Max: 10 mg. Alternatively, 0.15 mg/kg to be infused over 20 minutes. May repeat injection or infusion procedure every 12 hours as needed. Once control is achieved, maintain with oral doses of 50-100 mg daily.

Acute myocardial infarction
Adult: Within 12 hours of the onset of chest pain: Inject 5-10 mg slowly at a rate of 1 mg/minute, followed by an oral dose of 50 mg about 15 minutes later (if no adverse effects result from the injection). Alternatively, repeat IV dose of 5 mg 10 minutes after the initial dose followed by an oral dose of 50 mg 10 minutes after the last dose. A further oral dose of 50 mg may be given 12 hours after. Thereafter, maintain with 100 mg every 12 hours.

Adult: 50-100 mg once daily, titrate dose based on patient response.

Angina pectoris
Adult: 50-100 mg daily given as a single dose or in divided doses.

Thận trọng

Quá liều
Symptoms: Bradycardia, hypotension, bronchospasm, and acute cardiac failure; hypoglycaemia, impaired conduction, decreased cardiac contractility, heart block, shock, and cardiac arrest may also occur. Management: Initiate symptomatic and supportive treatment. Gastric lavage or activated charcoal may be used in acute atenolol overdose. IV atropine sulfate may be given for bradycardia and IV isoproterenol HCl for 2nd or 3rd degree AV block, a transvenous cardiac pacemaker may also be used. For severe hypotension, a vasopressor (e.g. dobutamine, norepinephrine) may be given. and for bronchospasm, a ß2-adrenergic agonist (e.g. isoproterenol, terbutaline). IV glucagon may also be useful if hypotension is refractory to vasopressors and IV glucose is used for hypoglycaemia. A cardiac glycoside, diuretic and oxygen should be used for cardiac failure. In severe cases, haemodialysis may be useful in enhancing elimination.
Tương tác
Additive effects with Ca channel blockers (e.g. verapamil, diltiazem) and catecholamine-depleting agents (e.g. reserpine). May increase atrioventricular conduction time with digitalis glycosides. May aggravate rebound hypertension following clonidine withdrawal. Class I anti-arrhythmic drugs (e.g. disopyramide) and amiodarone may potentiate effects on atrial-conduction time and induce negative inotropic effect. May increases hypoglycaemic effects of insulin and oral antidiabetic drugs. Decreased hypotensive effects with concomitant use of NSAIDs (e.g. ibuprofen, indometacin). May increases risk of hypotension and attenuates reflex tachycardia with anaesthetic drugs.
Lab Interference
May result to false-positive aldosterone/renin ratio (ARR).
Tác dụng
Description: Atenolol selectively and competitively blocks β1-adrenergic receptors but has little or no effect on β2-receptors except at high doses. It has negative inotropic effects without intrinsic sympathomimetic and membrane-stabilising activities.
Duration: Beta-blocking effect: Approx 12-24 hours. Antihypertensive effect: Approx 24 hours (oral).
Absorption: Rapid and consistent but incompletely absorbed from the gastrointestinal tract (approx 50%). Time to peak plasma concentration: 2-4 hours (oral).
Distribution: Poorly penetrates tissues due to low lipid solubility, crosses placenta and present in breast milk. Plasma protein-binding: 6-16%.
Metabolism: Limited or no hepatic metabolism.
Excretion: Via urine (40% as unchanged drug); faeces (50%). Elimination half-life: Approx 6-7 hours.
