"Mutations in the TTN gene, which are commonly found in idiopathic dilated cardiomyopathy, also seem common in peripartum cardiomyopathyâ€”which may finally help explain why the latter condition occurs, new research suggests.
CORGARD (nadolol) is indicated for the long-term management of patients with angina pectoris.
CORGARD (nadolol) is indicated for the treatment of hypertension, to lower blood pressure.
Lowering blood pressure reduces the risk of fatal and nonfatal cardiovascular events, primarily strokes and myocardial infarctions. These benefits have been seen in controlled trials of antihypertensive drugs from a wide variety of pharmacologic classes including the class to which this drug principally belongs. There are no controlled trials demonstrating risk reduction with CORGARD.
Control of high blood pressure should be part of comprehensive cardiovascular risk management, including, as appropriate, lipid control, diabetes management, antithrombotic therapy, smoking cessation, exercise, and limited sodium intake. Many patients will require more than one drug to achieve blood pressure goals. For specific advice on goals and management, see published guidelines, such as those of the National High Blood Pressure Education Program's Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC).
Numerous antihypertensive drugs, from a variety of pharmacologic classes and with different mechanisms of action, have been shown in randomized controlled trials to reduce cardiovascular morbidity and mortality, and it can be concluded that it is blood pressure reduction, and not some other pharmacologic property of the drugs, that is largely responsible for those benefits. The largest and most consistent cardiovascular outcome benefit has been a reduction in the risk of stroke, but reductions in myocardial infarction and cardiovascular mortality also have been seen regularly.
Elevated systolic or diastolic pressure causes increased cardiovascular risk, and the absolute risk increase per mmHg is greater at higher blood pressures, so that even modest reductions of severe hypertension can provide substantial benefit. Relative risk reduction from blood pressure reduction is similar across populations with varying absolute risk, so the absolute benefit is greater in patients who are at higher risk independent of their hypertension (for example, patients with diabetes or hyperlipidemia), and such patients would be expected to benefit from more aggressive treatment to a lower blood pressure goal.
Some antihypertensive drugs have smaller blood pressure effects (as monotherapy) in black patients, and many antihypertensive drugs have additional approved indications and effects (e.g., on angina, heart failure, or diabetic kidney disease). These considerations may guide selection of therapy.
CORGARD (nadolol) may be used alone or in combination with other antihypertensive agents, especially thiazide-type diuretics.
DOSAGE AND ADMINISTRATION
DOSAGE MUST BE INDIVIDUALIZED. CORGARD (NADOLOL) MAY BE ADMINISTERED WITHOUT REGARD TO MEALS.
The usual initial dose is 40 mg CORGARD (nadolol) once daily. Dosage may be gradually increased in 40 to 80 mg increments at 3 to 7 day intervals until optimum clinical response is obtained or there is pronounced slowing of the heart rate. The usual maintenance dose is 40 or 80 mg administered once daily. Doses up to 160 or 240 mg administered once daily may be needed.
The usefulness and safety in angina pectoris of dosage exceeding 240 mg per day have not been established. If treatment is to be discontinued, reduce the dosage gradually over a period of one to two weeks (see WARNINGS).
The usual initial dose is 40 mg CORGARD (nadolol) once daily, whether it is used alone or in addition to diuretic therapy. Dosage may be gradually increased in 40 to 80 mg increments until optimum blood pressure reduction is achieved. The usual maintenance dose is 40 or 80 mg administered once daily. Doses up to 240 or 320 mg administered once daily may be needed.
Dosage Adjustment in Renal Failure
Absorbed nadolol is excreted principally by the kidneys and, although nonrenal elimination does occur, dosage adjustments are necessary in patients with renal impairment. The following dose intervals are recommended:
|Creatinine Clearance (mL/min/1.73m²)||Dosage Interval (hours)|
CORGARD Tablets (Nadolol Tablets USP)
20 mg tablets in bottles of 100 (NDC 60793–800–01),
40 mg tablets in bottles of 100 (NDC 60793–801–01) and
80 mg tablets in bottles of 100 (NDC 60793–802–01).
All tablets are scored (bisect bar) and easy to break. Tablet identification numbers: 20 mg, 232; 40 mg, 207; and 80 mg, 241.
Store at room temperature; avoid excessive heat. Protect from light. Keep bottle tightly closed.
