    Notes: Abstract Blood concentrations of doxo- and epirubicin were studied in mice after i.v. or i.p. administration under normal and hypothermic conditions. The animals either were pretreated i.p. with chlorpromazine at 15 mg/kg and allowed to cool to a rectal temperature of 28 °C or were given saline i.p. with their rectal temperature remaining at 37 °C. The anthracyclines were 14-14C-labeled and were given at a dose of 0.85 mg/kg. Blood samples were taken at 5, 15, and 25 min and 2, 6, 24, and 48 hours after injection and were analyzed by liquid scintillation counting. The blood concentration related to time was similar for the two anthracyclines. The peak concentration was highest for i.v. administration and was higher for the hypothermic groups. The peak concentration and the area under the curve were highest under hypothermic conditions. The terminal half-life was longer after i.p. administration. The ratio calculated for the blood concentration under hypothermic/normothermic conditions over time was substantially increased after i.p. administration, the increase being most pronounced for epirubicin. The pharmacokinetic characteristics found might be related to the anthracycline toxicity encountered in tumor-inoculated mice treated at different body temperatures.

    Comparative pharmacokinetic study of adriamycin and 4'epi-adriamycin after their simultaneous intravenous administration (1986)
    Springer

    Notes: Summary The plasma pharmacokinetics of adriamycin and 4'epi-adriamycin have been studied in 6 patients with ovarian carcinoma after simultaneous intravenous administration of equal amounts of the two anthracyclines. A highly selective liquid chromatographic analytical method permitted quantification of plasma concentrations of the two drugs as well as their corresponding 13-hydroxy metabolites. The plasma concentrations of each drug followed a three-compartment open model, with great interindividual variation in the pharmacokinetic parameters. On average, the area under the plasma concentration time curve (AUC) and the maximum plasma concentration (Cmax) were 1.6- and 1.2-times larger for adriamycin than for 4'epi-adriamycin. 4'Epi-adriamycin was eliminated faster than adriamycin by 4 of the 6 patients, the average terminal half-life of the latter being 1.4-times longer. The plasma concentrations of the 13-hydroxy metabolites did not exceed 20 ng/ml. Their AUC values averaged 23% of those of the intact drugs.

    Pharmacokinetic study of IV infusions of adriamycin (1985)

    Notes: Summary The plasma pharmacokinetics of adriamycin has been studied in 21 cancer patients (31–85 years old) without liver tumours after short (3.00 min) and prolonged (45 min-16h) i.v. infusions. The area under the plasma concentration-time curve and the maximum plasma concentration compensated for dose variation showed a more than 3-fold individual variation. The pharmacokinetics of adriamycin was linear. There was no pharmacokinetic rational for variation of the dose with the age of the patients. There was good agreement between the measured plasma concentration-time curves for prolonged infusions and curves predicted from pharmacokinetic data from short term infusions.

    Food-induced increase in bioavailability of 5-methoxypsoralen (1994)

    Notes: Abstract 5-Methoxypsoralen (5-MOP) in combination with ultraviolet light exposure is used for the treatment of psoriasis. The effect of food on the pharmacokinetics of 5-MOP was evaluated in a randomized, crossover study in nine healthy subjects. Each subject received the tablets with a standardized breakfast or under fasting conditions. The food had a dramatic effect on the bioavailability of 5-MOP. Five of the subjects showed no measurable quantities (detection limit of the analytical technique 1 ng·ml-1) of 5-MOP when the drug was given under fasting conditions. However, plasma peak concentration within the range 37–144 ng·ml-1 (median 102 ng·ml-1) was measured when the drug was taken with food. The time for the plasma peak concentration was within the range 2.0–5.1 h (median 3.0 h) under non-fasting conditions. The elimination half-life was within the range 1.4–2.7 h (median 1.9 h). We conclude that it is imperative that 5-MOP tablets are administered together with food.

    Methotrexate in juvenile rheumatoid arthritis (1995)

    Notes: Abstract Children with juvenile rheumatoid arthritis (JRA) have been reported to require higher doses (per kg body weight) of methotrexate (MTX) than adults with rheumatoid arthritis to control their disease. The purpose of the present study was to characterise the plasma pharmacokinetics of MTX and its major metabolite, 7-hydroxymethotrexate (7-OHMTX) in children, and to compare the results with those previously obtained in adults. Thirteen patients (age 5–16 y) with JRA (median disease duration 5.5 y) were studied after once weekly oral administration of MTX (median 0.21 mg·kg−1). The analytical method was sufficiently sensitive to permit determination of plasma and urinary concentrations of MTX and 7-OHMTX during the entire dose interval in most of the patients. The dose normalized area under the plasma concentration versus time-curve (AUC) of MTX increased with the age of the children and was lower than previously found in adults. The dose normalized AUC of 7-OHMTX was not dependent on age. No correlation was found between the AUCs of MTX and 7-OHMTX. The results suggest that the age-dependence of the pharmacokinetics of MTX might explain the observation that at least some children require higher doses of MTX than adults to obtain a sufficient therapeutic effect.
