Quá liều
Symptoms: Hypotension, bradycardia, pulmonary oedema, syncope, cardiogenic shock, drowsiness, confusion, seizures, hallucinations, dilated pupils, bronchospasm, vomiting, and occasionally CNS-mediated respiratory depression. Management: Symptomatic and supportive treatment. For ingestion within 1 hour of more than the therapeutic dose, consider activated charcoal (50 g for adults, 1 g/kg for children) or gastric lavage (in adults for potentially life-threatening overdose). Administer atropine (3 mg IV for adult and 0.04 mg/kg for child) for bradycardia. Excessive bradycardia may be countered with atropine to 1-2 mg IV and/or require a cardiac pacemaker. If necessary, this may be followed with an IV bolus of glucagon 10 mg or glucagon 1-10 mg/hour IV infusion. If the patient does not respond to glucagon or if glucagon is unavailable, dobutamine 2.5-10 mcg/kg/minute IV infusion may be given. For severe hypotension, heart failure, or cardiogenic shock, administer glucagon (5-10 mg IV bolus for adults and 50-150 mcg/kg for child) over 10 minutes to reduce tendencies of vomiting, followed by 1-5 mg/hour infusion, titrated according to response. If glucagon is not available or the patient does not respond to glucagon, isoprenaline 5-10 mcg/minute for adults and 0.02 mcg/kg/minute in children may be given, increased according to response. In severe hypertension, administer dobutamine 2.5-40 mcg/min/minute (adults and children). For bronchospasm, nebulise 2.5-5 mg of salbutamol. In severe cases, give aminophylline 5 mg/kg IV over 30 minutes followed by an infusion of 0.5-1 mg/kg/hour. Do not give loading dose of 5 mg/kg if patient is taking oral theophylline or aminophylline. In cases of generalised spasm, diazepam 0.1-0.3 mg/kg IV may be used.
Tương tác
May have potentiating effects on arterial conduction time and induce additive negative or inotropic effect with propafenone, amiodarone, quinidine, flecainide and Ca channel blockers. Concomitant administration with catecholamine-depleting drugs (e.g. reserpine), MAOIs or TCAs may cause additive effects and potentiate hypotension. Reduced antihypertensive effect with NSAIDs (e.g. ibuprofen, indometacin). May enhance vasoconstrictive action of ergot alkaloids. Coadministration with warfarin increases its bioavailability and prothrombin time. May enhance hypoglycaemic effects of insulin. Increased risk of hypotension and attenuation of the reflex tachycardia with anaesthetic drugs. Increased plasma concentration with lidocaine.
Food Interaction
Alcohol may increase or decrease plasma levels of propranolol. Protein rich foods may increase bioavailability.
Lab Interference
May interfere with glaucoma screening, estimation of serum bilirubin by the diazo method, and determination of catecholamines by using fluorescence.
Tác dụng
Description: Propranolol is a nonselective ß-adrenergic blocker that competitively blocks ß1 and ß2-receptors resulting in decreased heart rate, myocardial contractility, BP and myocardial oxygen demand. It has negative inotropic effects and membrane-stabilising activities but does not possess intrinsic sympathomimetic activities.
Onset: 1-2 hours (oral).
Duration: Approx 6-12 hours (immediate-release); approx. 24-27 hours (extended-release).
Pharmacokinetics:
Absorption: Almost completely absorbed from the gastrointestinal tract. Bioavailability: Approx 25%. Time to peak plasma concentration: Approx 1-2 hours.
Distribution: Widely distributed, crosses the blood brain barrier and placenta, enters the breast milk. Volume of distribution: 4 L/kg. Plasma protein binding: Approx 90%.
Metabolism: Undergoes hepatic metabolism via CYP2D6 isoenzyme, and CYP1A2 to 4-hydroxypropranolol (biologically active).
Excretion: Mainly via urine (96-99%, <1% as unchanged drug). Elimination half-life: Approx 3-6 hours.
