Pharmacokinetic principles of antineoplastic drug therapy.

Determinants of host-drug interaction comprise a complex of potentially variable factors. The complexity of this variability compromises the forecasting of favorable response in individual patients given standard therapy. Substantial success with current forms of chemotherapy may require that biochemical, pharmacologic, and clinical profiles be established for each cancer patient whereby the use of drug and drug combination can be rationally applied. The significance of evaluating clinical pharmacokinetic parameters in patients with cancer is placed in perspective with other factors relevant to individual drug response.

Studies on the clinical pharmacokinetics of imidazopyrazole.

Plasma decay kinetics were analyzed for seven patients (400-5700 mg) during a Phase I clinical trial of imidazopyrazole. A two-compartment open pharmacokinetic model was able to account for the data. The median alpha-phase half-life was found to be 0.65 hour, with a median beta-phase half-life of 23.1 hours. Twelve per cent of the administered drug was excreted unchanged in 72 hours, whereas the total amount of imidazopyrazole equivalents excreted in that period was 38.6%. The median plasma equivalent space was found to be 15.9 l./m2, and volume of distribution at steady state was 40.2 l./m2. Renal and plasma clearance for imidazopyrazole was found to be 0.2 and 1.7 l./m2/hr, respectively.
