  • a Homozygous = *1/*1; Heterozygous = one *1 allele and one other allele (i.e., *3, *6, or *7; Expresser = mixed genotype wherein each subject had at least one *1 allele.

  • b Denotes clinical findings that were claimed to be statistically significant.

  • c Denotes clearance determined from an intravenous dose. All other clearance values are CL/F.

  • d Vincristine demonstrated a two fold increase in metabolite/parent ratio in *1 carriers.

  • e CL/F and Cmax differences were averaged for individual values reported for R- and S-verapamil.

  • f Value reported is steady-state plasma concentration.
