1. Higher doses may be given once daily, while lower doses are generally given twice daily. Venous blood samples were taken every 30 min for 4 h, then every 60 min for 4 h, and every 4 h for 16 h. The authors assessed whether their published pharmacokinetic parameters predicted the acetaminophen concentrations in the present study. The similarity between observed and predicted concentrations was assessed by comparing the plotted ratios with the target value (1.0).One hundred ninety of the 272 planned blood samples were obtained.

The TDx system was operated according to the manufacturer’s published recommendations. Children—Dose is based on weight or age. 2. For each patient, the ratio of measured to predicted concentration was determined and plotted against time. We did not collect pharmacodynamic data in our study subjects because our focus and study design was on pharmacokinetics. Paed Anaesth 1998; 8: 442–3van Hoogdalem EJ: Pharmacokinetics of rectal drug administration. High-dose rectal acetaminophen (25 to 45 mg/kg/dose) has been studied and recommended as an initial loading dose for pain management, as well as for the scheduled management of peri- and postoperative pain, in pediatric patients. Although one may expect rectal dosing would produce larger interindividual variability, the later data are surprisingly consistent between individuals.Our previously published pharmacokinetic parameter for volume of distribution, normalized for bioavailability, was recently questioned as lower than would be expected based on other studies.

Values for serum concentration of acetaminophen are plotted against time for each patient. Seven-day course of treatment - 250 mg three times daily for seven consecutive days.

There was no evidence of accumulation during the 24-h sampling period.ACETAMINOPHEN is often given to children during surgery for analgesia or antipyresis. A dose range of between 5 and 25 mg/lb given by mouth is typical. This site uses cookies. The Using single or multiple uncut combinations of a commercially available acetaminophen suppository in a hydrogenated vegetable oil base, an initial dose of 40 mg/kg and subsequent doses of 20 mg/kg at 6-h intervals achieved and maintained acetaminophen serum concentrations of 10–20 μg/ml during more than 50% of the period surveyed. All rights reserved. Purposes. Ages 12 years and older. Six patients received only the initial 40-mg/kg dose.Fig. The coefficients of variation were 7.5% and 4.3%, respectively, during the study.To assess whether our dosing regimen achieved the target concentration of 10–20 μg/ml, we determined the fraction of time that each individual maintained a serum acetaminophen concentration between 10 and 20 μg/ml from initial administration until 6 h after the final dose (or until the final sample was obtained). Dose is based on form and strength. Using single or multiple uncut combinations of a commercially available acetaminophen suppository in a hydrogenated vegetable oil base, an initial dose of 40 mg/kg and subsequent doses of 20 mg/kg at 6-h intervals achieved and maintained acetaminophen serum concentrations of 10–20 μg/ml during more than 50% of the period surveyed. However, because acetaminophen is more typically given as an analgesic during the postoperative period rather than as an antipyretic, the target acetaminophen concentration should be that necessary to produce analgesia rather than antipyresis.
