COREG

COREG is rapidly and extensively absorbed following oral administration, with absolute bioavailability of approximately 25% to 35% due to a significant degree of first-pass metabolism. Following oral administration, the apparent mean terminal elimination half-life of carvedilol generally ranges from 7 to 10 hours. Plasma concentrations achieved are proportional to the oral dose administered. When administered with food, the rate of absorption is slowed, as evidenced by a delay in the time to rea...

14.1 Heart Failure A total of 6,975 subjects with mild-to-severe heart failure were evaluated in placebo- controlled trials of carvedilol. Mild-to-Moderate Heart Failure Carvedilol was studied in 5 multicenter, placebo‑controlled trials, and in 1 active- controlled trial (COMET trial) involving subjects with mild-to-moderate heart failure. Four U.S. multicenter, double‑blind, placebo‑controlled trials enrolled 1,094 subjects (696 randomized to carvedilol) with NYHA class II‑III heart failure and ejection fraction less than or equal to 0.35. The vast majority were on digitalis, diuretics, and a...

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.

COREG is contraindicated in the following conditions: Bronchial asthma or related bronchospastic conditions. Deaths from status asthmaticus have been reported following single doses of COREG. Second- or third-degree AV block. Sick sinus syndrome. Severe bradycardia (unless a permanent pacemaker is in place). Patients with cardiogenic shock or who have decompensated heart failure requiring the use ...

Acute exacerbation of coronary artery disease upon cessation of therapy: Do not abruptly discontinue. ( 5.1 ) Bradycardia, hypotension, worsening heart failure/fluid retention may occur. Reduce the dose as needed. ( 5.2 , 5.3 , 5.4 ) Non-allergic bronchospasm (e.g., chronic bronchitis and emphysema). Avoid β-blockers. ( 4 ) However, if deemed necessary, use with caution and at lowest effective dose. ( 5.5 ) Diabetes: May mask symptoms of hypoglycemia and alter glucose levels; monitor. ( 5.6 ) 5....

7 DRUG INTERACTIONS CYP P450 2D6 enzyme inhibitors may increase and rifampin may decrease carvedilol levels. ( 7.1 , 7.5 ) Hypotensive agents (e.g., reserpine, MAO inhibitors, clonidine) may increase the risk of hypotension and/or severe bradycardia. ( 7.4 ) Cyclosporine or digoxin levels may increase. ( 7.3 , 7.4 ) Both digitalis glycosides and β-blockers slow atrioventricular conduction and decr...
