Detailed View: Safety Labeling Changes Approved By FDA Center for Drug Evaluation and Research (CDER) -- June 2009
WARNINGS AND PRECUATIONS
- In a trial comparing heart failure patients switched to Coreg CR or maintained on immediate-release carvedilol, there was a 2-fold increase in the combined incidence of hypotension, syncope or dizziness in elderly patients (> 65 years) switched from the highest dose of carvedilol (25 mg twice daily) to Coreg CR 80 mg once daily.
USE IN SPECIFIC POPULATIONS
- A randomized study (n = 405) comparing mild to severe heart failure patients switched to Coreg CR or maintained on immediate-release carvedilol included 220 patients who were 65 years of age or older. In this elderly subgroup, the combined incidence of dizziness, hypotension, or syncope was 24% (18/75) in patients switched from the highest dose of immediate-release carvedilol (25 mg twice daily) to the highest dose of Coreg CR (80 mg once daily) compared to 11% (4/36) in patients maintained on immediate release carvedilol (25 mg twice daily). When switching from the higher doses of immediate-release carvedilol to COREG CR, a lower starting dose is recommended for elderly patients.
