Pharmacokinetic Modeling of Methadone

Sponsor: University Hospital, Montpellier

Summary

The management of patients with opioid addiction is a challenge insofar as many distractors or variability factors can interfere with the control of the addiction, whether they are psychological, psychiatric, environmental, pharmacokinetic or pharmacodynamic. Understanding this variability is potentially to be able to adjust a priori a dosage and to identify the factors of clinical response. Few population pharmacokinetic models exist for methadone and they generally concern the management of pain in palliative care patients or the management of opioid withdrawal syndrome in neonates. The hypothesis is therefore that the creation of such a model would make it possible to reduce patients' withdrawal periods, to set a target for plasma concentrations with a view to reducing dosages, and to empower the patient in his choice to monitor blood concentrations facilitated by a minimally invasive sampling device.
