Data summary: comparison of the Kp estimates among different routes of administration, including a single intravenous bolus (3 mg/kg, i.v.; N = 3 to 4 at each time point), an oral dose (30 mg/kg, PO; N = 4 at each time point), or a continuous steady-state intraperitoneal infusion (40 µg/h, i.p.; N = 4 in each genotype)
Data are presented as the mean. Data for the wild-type genotype after administration of a single oral dose were previously reported (Laramy et al., 2017) and are included in this present study to compare with the three other genotypes that lack efflux transporters.
