    Notes: Abstract. A total of 23 women with stage II breast cancer receiving adjuvant cyclophosphamide, methotrexate and 5-fluorouracil had detailed pharmacokinetic monitoring performed on the first and third courses of therapy. The area under the concentration time curve (AUC) of each of these three drugs varied by a factor of 3–4 among patients. No systematic change in pharmacokinetics between the first and third courses was seen for cyclophosphamide, methotrexate or 5-fluorouracil, and the mean AUC for each of the three drugs did not change. However, significant intrapatient variability in drug pharmacokinetics was observed for all three drugs such that the AUC, clearance and half-life in an individual on the third course could not be reliably predicted from data generated on the first course. On the basis of these results, cyclophosphamide, methotrexate, and 5-fluorouracil pharmacokinetic data from one treatment would not be useful information from which the doses for subsequent courses could be determined.

    Notes: Abstract  Modulation of 5-fluorouracil (FUra) using leucovorin (LV) is a standard treatment approach in patients with metastatic colorectal cancer. Modulation of FUra with interferon alfa has also shown some promise. Laboratory data have demonstrated increased cytotoxicity when FUra is combined with both LV and interferon. The current study examined the effects of double modulation of FUra using LV and interferon.Patients with measurable advanced colorectal cancer received bolus FUra 375 mg/m2 plus LV 20 mg/m2 daily for 5 days, repeated every 28 days. Recombinant human interferon alfa-2a, 3 million IU/m2 subcutaneously, was given daily on the days of chemotherapy then three times weekly. There was one complete response and nine partial responses (10/41) seen for an overall response rate of 24% (95% CI 12.0–40.0%). Overall, 70% of patients experienced one or more episodes of nonhematologic toxicity of grade 3 or more. Weight loss was common, with a mean decrease of 2.9 kg over the first two months (P〈0.0001). Improvements in tumor-related symptoms were balanced by increased fatigue and a deterioration in body weight and performance status. There was no evidence of progressive changes in FUra metabolism from interferon usage.

    Notes: Summary In eight normal volunteers, the combination of ethanol (0.5 g/kg) and diazepam (10 mg) administered orally produced a greater decrease in motor performance on a pursuit rotor than diazepam alone. The pharmacologic effect of diazepam was enhanced by 73% and this potentiation was associated with significantly greater diazepam concentrations (p〈0.01) than after diazepam alone. The failure to observe any increase in the concentrations of the principal metabolite, N-desmethyl diazepam, during the period of enhanced pharmacologic effect precludes any change in the demethylating metabolic process as being responsible. The data suggest (0.10〉p〉0.05) a trend to a smaller volume of distribution of diazepam when ethanol is administered prior to diazepam ingestion. The subjects showed acute tolerance to the effects of diazepam. Lower plasma concentrations on the ascending side of the plasma diazepam concentration versus time profile were linked with the same pharmacologic responses associated with a greater drug concentration on the descending portion, of the same curve.
