Population Pharmacokinetic and Pharmacodynamic Modeling of Microemulsion Propofol in Healthy Volunteers: Comparison With Lipid Emulsion Propofol
In Brief
A Phase 1 clinical trial evaluating propofol for Healthy. Completed, enrolled 63 participants across 1 site.
Detailed Summary
AquafolTM (Daewon Pharmaceutical Co., Ltd., Seoul, Korea) is a microemulsion propofol that has been developed for eliminating lipid solvent-related adverse events of long chain triglyceride emulsion (LCT) propofol (Diprivan®; AstraZeneca, London, United Kingdom), such as infection, fat embolism, hypertriglyceridemia and pancreatitis. Originally, AquafolTM was formulated with 8% polyethylene glycol 660 hydroxystearate (Solutol HS 15, BASF Company Ltd., Seoul, Korea) and 5% tetrahydrofurfuryl alcohol polyethylene glycol ether (Glycofurol, Roche, Basle, Switzerland). A phase 1 study to assess the safety and tolerability of polymeric vehicles of this formulation in healthy volunteers showed dose-limiting toxicity. Subsequently, it was reformulated with 10% purified poloxamer 188 (PP188) as a nonionic block copolymer surfactant and 0.7% polyethylene glycol 660 hydroxystearate as a nonionic surfactant. Alterations in propofol formulation may result in altered pharmacokinetic, pharmacodynamic characteristics. The aim of this study was to compare the pharmacokinetics and pharmacodynamics of propofol microemulsion and lipid emulsion, using noncompartmental analysis and population analysis with mixed effects modeling.

Timeline
Interventions
Each subject received both propofol formulations in a crossover fashion separated by a 7-day washout period, and the order of the drug administration was randomized. Subjects received both propofol formulations (Lipid emulsion propofol: Diprivan® and Microemulsion propofol: AquafolTM) during 60 min. The infusion rate was assigned according to a nonblinded, randomized design to 1.5, 3, 6, or 12 mg/kg/hr.
