Total, Unbound Plasma and Salivary Phenytoin Levels in Critically Ill Patients
Objective: To assess the reliability of salivary phenytoin (PHT) concentrations and predicted free PHT levels by Sheiner-Tozer equation in order to substitute measured free PHT concentrations in critically ill patients. Methodology: Twenty-four neurocritically ill adult patients receiving intravenous PHT were included in the study. Analyses of total, free plasma and saliva PHT concentrations we...
متن کاملClinical decision support of therapeutic drug monitoring of phenytoin: measured versus adjusted phenytoin plasma concentrations
BACKGROUND Therapeutic drug monitoring of phenytoin by measurement of plasma concentrations is often employed to optimize clinical efficacy while avoiding adverse effects. This is most commonly accomplished by measurement of total phenytoin plasma concentrations. However, total phenytoin levels can be misleading in patients with factors such as low plasma albumin that alter the free (unbound) c...
متن کاملDifferences between the Measured and Calculated Free Serum Phenytoin Concentrations in Epileptic Patients
PURPOSE The pharmacokinetics of phenytoin is complicated by genetic and environmental differences. It is, therefore, important to monitor the serum concentrations in patients who receive phenytoin. Because most of the phenytoin in serum is bound to proteins, the level of serum albumin influences the amount of free phenytoin. MATERIALS AND METHODS We compared the measured and calculated free p...
