COREG CR

AbsorptionCarvedilol is rapidly and extensively absorbed following oral administration of immediate-release carvedilol tablets, with an absolute bioavailability of approximately 25% to 35% due to a significant degree of first-pass metabolism. COREG CR extended-release capsules have approximately 85% of the bioavailability of immediate-release carvedilol tablets. For corresponding dosages [see Dosage and Administration (2) ] , the exposure (AUC, C max , trough concentration) of carvedilol as COR...

Support for the use of COREG CR extended-release capsules for the treatment of mild-to-severe heart failure and for patients with left ventricular dysfunction following myocardial infarction is based on the equivalence of pharmacokinetic and pharmacodynamic (β 1 -blockade) parameters between COREG CR and immediate-release carvedilol [see Clinical Pharmacology (12.2 , 12.3) ] . The clinical trials performed with immediate-release carvedilol in heart failure and left ventricular dysfunction following myocardial infarction are presented below. 14.1 Heart Failure A total of 6,975 subjects with mil...

The safety profile of COREG CR was similar to that observed for immediate-release carvedilol. Most common adverse events seen with immediate-release carvedilol ( 6.1 ): Heart failure and left ventricular dysfunction following myocardial infarction (≥10%): Dizziness, fatigue, hypotension, diarrhea, hyperglycemia, asthenia, bradycardia, weight increase. Hypertension (≥5%): Dizziness. To report SUSPECTED ADVERSE REACTIONS, contact Waylis Therapeutics at 1-844-200-7910 or FDA at 1-800-FDA-1088 or ww...

COREG CR is contraindicated in the following conditions: Bronchial asthma or related bronchospastic conditions. Deaths from status asthmaticus have been reported following single doses of immediate-release carvedilol. 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 ...

In clinical trials of COREG CR in subjects with hypertension (338 subjects) and in subjects with left ventricular dysfunction following a myocardial infarction or heart failure (187 subjects), the profile of adverse events observed with carvedilol phosphate was generally similar to that observed with the administration of immediate-release carvedilol. Therefore, the information included within this section is based on data from controlled clinical trials with COREG CR as well as immediate-releas...

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. ( 7.2 ) Cyclosporine or digoxin levels may increase. ( 7.3 , 7.4 ) Both digitalis glycosides and β-blockers slow atrioventricular conduction and decr...
