Metoprololdosage

Administer once daily. Titrate at weekly or longer intervals as needed and tolerated.

Hypertension: Starting dose is 25 to 100 mg.

Angina Pectoris: Starting dose is 100 mg.

Heart Failure: Starting dose is 12.5 or 25 mg. Switching from immediate-release metoprolol to TOPROL-XL: use the same total daily dose of TOPROL-XL.

2.1 Hypertension

Adults: The usual initial dosage is 25 to 100 mg daily in a single dose. Adjust dosage at weekly (or longer) intervals until optimum blood pressure reduction is achieved. In general, the maximum effect of any given dosage level will be apparent after 1 week of therapy. Dosages above 400 mg per day have not been studied. Pediatric Hypertensive Patients ≥ 6 Years of age: The recommended starting dose of TOPROL-XL is 1 mg/kg once daily, but the maximum initial dose should not exceed 50 mg once daily. Adjust dosage according to blood pressure response. Doses above 2 mg/kg (or in excess of 200 mg) once daily have not been studied in pediatric patients. TOPROL-XL has not been studied in pediatric patients < 6 years of age.

2.2 Angina Pectoris

Individualize the dosage of TOPROL-XL. The usual initial dosage is 100 mg daily, given in a single dose. Gradually increase the dosage at weekly intervals until optimum clinical response has been obtained or there is a pronounced slowing of the heart rate. Dosages above 400 mg per day have not been studied. If treatment is to be discontinued, reduce the dosage gradually over a period of 1 - 2 weeks.

2.3 Heart Failure

Dosage must be individualized and closely monitored during up-titration. Prior to initiation of TOPROL-XL, stabilize the dose of other heart failure drug therapy. The recommended starting dose of TOPROL-XL is 25 mg once daily for two weeks in patients with NYHA Class II heart failure and 12.5 mg once daily in patients with more severe heart failure. Double the dose every two weeks to the highest dosage level tolerated by the patient or up to 200 mg of TOPROL-XL. Initial difficulty with titration should not preclude later attempts to introduce TOPROL-XL. If patients experience symptomatic bradycardia, reduce the dose of TOPROL-XL. If transient worsening of heart failure occurs, consider treating with increased doses of diuretics, lowering the dose of TOPROL-XL, or temporarily discontinuing it. The dose of TOPROL-XL should not be increased until symptoms of worsening heart failure have been stabilized. 2.4 Administration TOPROL-XL tablets are scored and can be divided; however, do not crush or chew the whole or half tablet.
