Workshop: September 27-29, 2001

A Hands-on Workshop on Parametric and Nonparametric Population PK and PD Modelling and its Applications in Therapeutic Drug Monitoring.

Thursday through Saturday, September 27-29, 2001, University of Navarra, Pamplona, Spain.

This course is intended for physicians, pharmacists, and biomedical scientists with an interest in population pharmacokinetic/pharmacodynamic modelling and also for those interested in therapeutic drug monitoring and optimal individualization of drug therapy for optimal clinical care of patients. Prior experience in clinical pharmacokinetics will be an advantage. Participants will be introduced to the USC*PACK software program which can be used both for therapeutic drug monitoring as well as for parametric and nonparametric population PK/PD and physiological modelling.

Co-coordinators:

Azucena Aldaz, Ph.D., Faculty of Pharmacy, University of Navarra

Roger W. Jelliffe, M.D., Professor of Medicine, USC School of Medicine, Director, USC Laboratory of Applied Pharmacokinetics.
