12.1 Mechanism of Action Carvedilol is a racemic mixture in which nonselective β-adrenoreceptor blocking activity is present in the S(-) enantiomer and α 1 -adrenergic blocking activity is present in both R(+) and S(-) enantiomers at equal potency. Carvedilol has no intrinsic sympathomimetic activity.

Carvedilol tablets are an alpha/beta-adrenergic blocking agent indicated for the treatment of: mild to severe chronic heart failure ( 1.1 ) left ventricular dysfunction following myocardial infarction in clinically stable patients( 1.2 ) hypertension( 1.3 ) 1.1 Heart Failure Carvedilol tablets are indicated for the treatment of mild-to-severe chronic heart failure of ischemic or cardiomyopathic origin, usually in addition to diuretics, ACE inhibitors, and digitalis, to increase survival and, also, to reduce the risk of hospitalization [see ( 7.4 ), Clinical Studies ( 14.1 )] . 1.2 Left Ventricular Dysfunction following Myocardial Infarction Carvedilol tablets are indicated to reduce cardiovascular mortality in clinically stable patients who have survived the acute phase of a myocardial infarction and have a left ventricular ejection fraction of less than or equal to 40% (with or without symptomatic heart failure) [see Clinical Studies ( 14.2 )] . 1.3 Hypertension Carvedilol tablets are indicated for the management of essential hypertension [see Clinical Studies ( 14.3 , 14.4 )] . It can be used alone or in combination with other antihypertensive agents, especially thiazide-type diuretics [see ( 7.2 )] .

Take with food. Individualize dosage and monitor during up-titration. ( 2 ) Heart failure: Start at 3.125 mg twice daily and increase to 6.25, 12.5, and then 25 mg twice daily over intervals of at least 2 weeks. Maintain lower doses if higher doses are not tolerated. ( 2.1 ) Left ventricular dysfunction following myocardial infarction: Start at 6.25 mg twice daily and increase to 12.5 mg then 25 mg twice daily after intervals of 3 to 10 days. A lower starting dose or slower titration may be used.( 2.2 ) Hypertension: Start at 6.25 mg twice daily and increase if needed for blood pressure control to 12.5 mg and then 25 mg twice daily over intervals of 1 to 2 weeks.( 2.3 ) Carvedilol should be taken with food to slow the rate of absorption and reduce the incidence of orthostatic effects. 2.1 Heart Failure DOSAGE MUST BE INDIVIDUALIZED AND CLOSELY MONITORED BY A PHYSICIAN DURING UP-TITRATION. Prior to initiation of Carvedilol tablets, it is recommended that fluid retention be minimized. The recommended starting dose of Carvedilol tablets are 3.125 mg twice daily for 2 weeks. If tolerated, patients may have their dose increased to 6.25, 12.5, and 25 mg twice daily over successive intervals of at least 2 weeks. Patients should be maintained on lower doses if higher doses are not tolerated. A maximum dose of 50 mg twice daily has been administered to patients with mild-to-moderate heart failure weighing over 85 kg (187 lbs). Patients should be advised that initiation of treatment and (to a lesser extent) dosage increases may be associated with transient symptoms of dizziness or lightheadedness (and rarely syncope) within the first hour after dosing. During these periods, patients should avoid situations such as driving or hazardous tasks, where symptoms could result in injury. Vasodilatory symptoms often do not require treatment, but it may be useful to separate the time of dosing of Carvedilol tablets from that of the ACE inhibitor or to reduce temporarily the dose of the ACE inhibitor. The dose of Carvedilol tablets should not be increased until symptoms of worsening heart failure or vasodilation have been stabilized. Fluid retention (with or without transient worsening heart failure symptoms) should be treated by an increase in the dose of diuretics. The dose of Carvedilol tablets should be reduced if patients experience bradycardia (heart rate less than 55 beats per minute)....

Most common adverse events ( 6.1 ): Heart failure and left ventricular dysfunction following myocardial infarction (≥10%): Dizziness, fatigue, hypotension, diarrhea, hyperglycemia, asthenia, bradycardia, weight increase. Hypertension (≥5%): Dizziness.

Carvedilol tablets have been evaluated for safety in subjects with heart failure (mild, moderate, and severe), in subjects with left ventricular dysfunction following myocardial infarction and in hypertensive subjects. The observed adverse event profile was consistent with the pharmacology of the drug and the health status of the subjects in the clinical trials. Adverse events reported for each of these patient populations are provided below. Excluded are adverse events considered too general to be informative, and those not reasonably associated with the use of the drug because they were associated with the condition being treated or are very common in the treated population. Rates of adverse events were generally similar across demographic subsets (men and women, elderly and non-elderly, blacks and non-blacks). Heart Failure Carvedilol tablets have been evaluated for safety in heart failure in more than 4,500 subjects worldwide of whom more than 2,100 participated in placebo-controlled clinical trials. Approximately 60% of the total treated population in placebo-controlled clinical trials received Carvedilol tablets for at least 6 months and 30% received Carvedilol tablets for at least 12 months. In the COMET trial, 1,511 subjects with mild-to-moderate heart failure were treated with Carvedilol tablets for up to 5.9 years (mean: 4.8 years). Both in US clinical trials in mild-to-moderate heart failure that compared Carvedilol tablets in daily doses up to 100 mg (n = 765) with placebo (n = 437), and in a multinational clinical trial in severe heart failure (COPERNICUS) that compared Carvedilol tablets in daily doses up to 50 mg (n = 1,156) with placebo (n = 1,133), discontinuation rates for adverse experiences were similar in carvedilol and placebo subjects....

Bronchial asthma or related bronchospastic conditions. ( 4 ) Second- or third-degree AV block. ( 4 ) Sick sinus syndrome. ( 4 ) Severe bradycardia (unless permanent pacemaker in place).
