title: Lack of evidence for polymorphism in metoprolol metabolism.
abstract: The claim for polymorphism in the metabolism of metoprolol is based on a logical fallacy. A frequency distribution of metoprolol AUC data is presented and, although highly skewed, no evidence of more than a single population is apparent. Plasma and urine metoprolol and metabolite data are also presented to support this.
