A Universal Pharmacokinetic Model for Dexmedetomidine in Children and Adults

A universal pharmacokinetic model was developed from pooled paediatric and adult data (40.6 postmenstrual weeks, 70.8 years, 3.1-152 kg). A three-compartment pharmacokinetic model with first-order elimination was superior to a two-compartment model to describe these pooled dexmedetomidine data. Population parameter estimates (population parameter variability %) were clearance (CL) 0.9 L/min/70 kg (36); intercompartmental clearances (Q2) […]

Modeling of The Relationship Between Ustekinumab Exposure, Fecal Calprotectin and Endoscopic Outcomes in Patients with Crohn’s Disease

Background: Ustekinumab is approved for the treatment of patients with moderate-to-severe Crohn’s disease (CD) and ulcerative colitis. In the UNITI endoscopy sub-study, only 17.4% of patients on ustekinumab achieved endoscopic response and 10.9% of patients achieved endoscopic remission at week 44 (w44).1 Aims: We aimed to investigate if improved endoscopic outcomes could be achieved through dose optimization […]

External Evaluation of Vancomycin Models

Introduction Current clinical evidence supports area under the concentration-time curve (AUC) rather than trough concentrations as a more rational target for vancomycin therapy (1). In mid-2019 practice at Auckland District Health Board Hospitals transitioned from trough concentration to AUC guided dosing supported by Bayesian forecasting using the GAVamycin model implemented in NextDose ( To support […]
