Important Safety Information About TOPROL-XL(R) (metoprolol succinate) Extended-Release Tablets
TOPROL-XL is a beta(1)-selective (cardioselective) adrenoceptor-blocking agent, for oral administration, available as extended-release tablets. TOPROL-XL has been formulated to provide a controlled and predictable release of metoprolol for once-daily administration.
TOPROL-XL is indicated for the treatment of hypertension, alone or in combination with other antihypertensives; the long-term treatment of angina pectoris; and the treatment of stable, symptomatic (NYHA Class II or III) heart failure of ischemic, hypertensive, or cardiomyopathic origin. It was studied in heart failure patients already receiving ACE inhibitors, diuretics, and, in the majority of cases, digitalis.
TOPROL-XL is contraindicated in severe bradycardia, heart block greater than first degree, cardiogenic shock, decompensated cardiac failure, and sick sinus syndrome (unless a permanent pacemaker is in place) and in patients who are hypersensative to any component of this product.
Patients taking TOPROL-XL should avoid abrupt cessation of therapy. Following abrupt cessation of therapy with certain beta-blocking agents, exacerbations of angina pectoris and, in some cases, myocardial infraction have occurred. The dosage should be reduced gradually over a one-to-two-week period, and the patient should be carefully monitored.
TOPROL-XL should be used with caution in patients who have bronchospastic disease, diabetes, thyrotoxicosis, peripheral vascular disease, who are undergoing major surgery, or who take calcium channel blockers of the verapamil and diltiazem type.
