The Monte Carlo Parametric Expectation Maximization (MC-PEM) algorithm can approximate the true log-likelihood as precisely as needed and is efficiently parallelizable. Our objectives were to evaluate an importance sampling version of the MC-PEM algorithm for mechanistic models and to qualify the default estimation settings in SADAPT-TRAN. We assessed bias,(More)
This review aims to introduce the concepts and principles underpinning the time course of drug effects. Models describing the time course of drug concentrations (pharmacokinetic models) and the ensuing concentration-effect (pharmacodynamics models) as well as the linked time-effect (pharmacokinetic-pharmacodynamic models) are introduced. Different types of(More)
Polymyxin combination therapy is increasingly used clinically. However, systematic investigations of such combinations are a relatively recent phenomenon. The emerging pharmacodynamic (PD) and pharmacokinetic (PK) data on CMS/colistin and polymyxin B suggest that caution is required with monotherapy. Given this situation, polymyxin combination therapy has(More)
Enterohepatic recirculation (EHC) can greatly enhance plasma drug exposures and therapeutic effects. This study aimed to develop a population pharmacokinetic model that can simultaneously characterize the extent and time-course of EHC in three species using fimasartan, a novel angiotensin II receptor blocker, as a model drug. All fimasartan plasma(More)
This report describes a pharmacokinetic/pharmacodynamic model for pramlintide, an amylinomimetic, in type 1 diabetes mellitus (T1DM). Plasma glucose and drug concentrations were obtained following bolus and 2-h intravenous infusions of pramlintide at three dose levels or placebo in 25 T1DM subjects during the postprandial period in a crossover study. The(More)
This study examines the pharmacokinetics of oral doses of lithium carbonate immediate-release capsules after administration of 600 or 900 mg in children and adolescents with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, bipolar I disorder. Lithium plasma concentrations were followed over 48 to 72 hours in 39 subjects (20 male and 19(More)
