Additional dosage information:
Usual Adult Dose for Hypertension
Initial dose: 40 mg orally twice a day or 80 mg sustained release once a day, whether used alone or added to a diuretic. The dose should be administered at bedtime (approximately 10 PM).
Maintenance dose: 120 to 240 mg/day or 120 to 160 mg/day of sustained release
Maximum dose: 640 mg/day.
Usual Adult Dose for Angina Pectoris
Total daily doses of 80 to 320 mg orally 2 to 4 times a day have been shown to increase exercise tolerance and to reduce ischemic changes in the ECG.
Sustained release: Initial dose: 80 mg orally once a day. Dosage should be gradually increased at 3 to 7 day intervals. The average optimal dosage appears to be 160 mg/day.
Usual Adult Dose for Arrhythmias
Oral: 10 to 30 mg 3 to 4 times a day, before meals and at bedtime.
IV: 1 to 3 mg at a rate not exceeding 1 mg/min.
Sufficient time should be allowed for the drug to reach the site of action even when a slow circulation is present. A second dose may be given after 2 minutes. Thereafter, additional drug should not be given in less than 4 hours. Additional propranolol should not be given when the desired alteration in rate and/or rhythm is achieved.
Usual Adult Dose for Myocardial Infarction
180 to 240 mg/day in 3 to 4 divided doses.
Usual Adult Dose for Migraine Prophylaxis
Initial dose: 80 mg/day orally in divided doses.
Maintenance dose: 160 to 240 mg/day.
The dosage may be increased gradually to achieve optimum migraine prophylaxis. If a satisfactory response is not obtained within 4 to 6 weeks after reaching the maximum dose, propranolol therapy should be discontinued.
Sustained release: Initial dose: 80 mg orally once a day.
Maintenance dose: 160 to 240 mg once a day.
Usual Adult Dose for Benign Essential Tremor
Initial dose: 40 mg orally twice a day.
Maintenance dose: 120 to 320 mg/day.
Optimum reduction of essential tremor is usually achieved with a dose of 120 mg/day.
Occasionally, it may be necessary to administer 240 to 320 mg/day.
Usual Adult Dose for Aortic Stenosis
20 to 40 mg orally 3 to 4 times a day, before meals and at bedtime.
Sustained release: 80 to 160 mg orally once a day.
Usual Adult Dose for Pheochromocytoma
Preoperatively: 60 mg/day orally in divided doses for 3 days prior to surgery, concomitantly with an alpha-adrenergic blocking agent.
Management of Inoperable Tumor: 30 mg/day orally in divided doses.
Usual Pediatric Dose for Arrhythmias
Oral: Children: Initial: 0.5 to 1 mg/kg/day in divided doses every 6 to 8 hours; titrate dosage upward every 3 to 5 days; usual dose: 2 to 4 mg/kg/day; higher doses may be needed; do not exceed 16 mg/kg/day
IV: Children: 0.01 to 0.1 mg/kg slow IV over 10 minutes; maximum dose: 1 mg (infants); 3 mg (children).
Usual Pediatric Dose for Hypertension
Immediate release formulations:
Initial: 0.5 to 1 mg/kg/day in divided doses every 6 to 12 hours; increase gradually every 5 to 7 days
Usual dose: 1 to 5 mg/kg/day
Maximum dose: 8 mg/kg/day
Children and Adolescents 1 to 17 years:
Immediate release formulations:
Initial: 1 to 2 mg/kg/day divided in 2 to 3 doses/day; titrate dose to effect
Maximum dose: 4 mg/kg/day up to 640 mg/day; sustained release formulation may be dosed once daily. (National High Blood Pressure Education Program Working Group on High Blood Pressure in Children and Adolescents).
Usual Pediatric Dose for Thyrotoxicosis
Neonates: Oral: 2 mg/kg/day in divided doses every 6 to 12 hours; occasionally higher doses may be required.
Adolescents: Oral: 10 to 40 mg/dose every 6 hours.
Renal Dose Adjustments
No adjustment recommended
Liver Dose Adjustments
Because propranolol is extensively metabolized by the liver, consideration should be given to lowering the dosage in patients with hepatic insufficiency.
The time needed for full antihypertensive response to a given dosage is variable and may range from a few days to several weeks.
Some patients, especially when lower doses are used, may experience a modest rise in blood pressure toward the end of the 12-hour dosing interval. This can be evaluated by measuring blood pressure near the end of the dosing interval. If control is not adequate, a larger dose, or 3-times-daily therapy may achieve better control.
The sustained release dose may be increased to 120 mg once a day or higher, until adequate blood pressure control is achieved.
Safety and effectiveness of propranolol extended release have not been established in pediatric patients (less than 18 years of age).
Propranolol is not significantly dialyzable.
The extended release product InnoPran XL should be taken once daily in the evening.
Compared with Caucasian patients, Black patients have a reduced blood pressure response to monotherapy with beta-blockers; however, the reduced response is largely eliminated if combination therapy that includes an adequate dose of a diuretic is instituted.
