A pharmacokinetic-pharmacodynamic model for cardiovascular safety assessment of R1551

Pharmacokinetic-pharmacodynamic relationships are crucial in understanding a drug’s arrhythmogenic potential. Models assist to quantitatively relate parent and metabolite concentrations to adverse electrocardiographic effects, including an apparent delay between effect and circulating parent species concentration. Here, we used an effect compartment model to investigate PR and QRS prolongation previously observed in preclinical studies with the NK1-NK3 […]

Modeling disease progression in acute stroke using clinical assessment scales.

This article demonstrates techniques for describing and predicting disease progression in acute stroke by modeling scores measured using clinical assessment scales, accommodating dropout as an additional source of information. Scores assessed using the National Institutes of Health Stroke Scale and the Barthel Index in acute stroke patients were used to model the time course of […]
