The authors examined the effect of tamoxifen (TAM), a multiple-drug resistance modulator, on the pharmacokinetics of doxorubicin (DOX) in patients with non-Hodgkin's lymphoma treated according to the CHOP-protocol which included DOX, cyclophosphamide, vincristine, and prednisone. The dose of DOX was 50 mg/m2, but was reduced 25% if the patient was older than 60 years. Of these, 10 randomly-selected patients received a daily dose of 480 mg of TAM (Group-1) and 10 others did not (Group-2). Blood samples were collected at different time intervals, and DOX was measured in plasma by liquid chromatography. The concentration-time data of DOX exhibited the characteristics of the two-compartment open model well. The mean (SEM) values of alpha, beta, k12, k21, k10, Vc, Vss, AUC, total clearance, and mean residence time observed in Group-1 were 4.06 (0.96) hr(-1), 0.0395 (0.0068) hr(-1), 3.13 (0.79) hr(-1), 0.264 (0.052) hr(-1), 0.708 (0.19) hr(-1), 525 (156) l/m2, 1060 (163) l/m2, 1145 (234) microg x hr/l, 49.3 (8.5) l/hr x m2, and 26.8 (6.6) hours, respectively. Those in Group-2 were 4.99 (1.13) hr(-1), 0.0432 (0.0073) hr(-1), 2.46 (0.63) hr(-1), 0.111 (0.026) hr(-1), 2.46 (0.86) hr(-1), 231 (53) l/m2, 812 (149) l/m2, 1690 (276) microg x hr/l, 30.3 (4.1) l/hr x m2, and 29.7 (5.1) hours, respectively. Of these parameters, the difference between the two groups was significant (p < or = 0.0169) only in k21. Thus, the coadministration of TAM at the earlier-mentioned dose appears generally to have no significant influence on the pharmacokinetics of doxorubicin when used in the CHOP-protocol.
