Metoprolol CR/XL in the treatment of chronic heart failure.

Metoprolol CR/XL (metoprolol succinate extended-release tablets) is a beta1-selective agent that improved survival and reduced hospitalization among patients with New York Heart Association class II-IV heart failure in a randomized trial. Metoprolol CR/XL differs from conventional metoprolol tartrate with respect to pharmacokinetic and pharmacodynamic properties that may be clinically important in patients with heart failure. A thorough patient evaluation should be performed to determine optimal dosage and titration of this drug, as with any beta-blocker, and to assess the potential for drug-drug or drug-disease interactions. By applying knowledge of drug-specific characteristics and designing therapy for each individual patient, improvement in patient outcomes can be realized with metoprolol CR/XL.
