Population pharmacokinetics
Population pharmacokinetics describes variation in drug exposure across a population using models that distinguish typical parameters from between-person and residual variation.

Structural model
An appropriate model specifies absorption, distribution and elimination behavior using parameters such as clearance and volume of distribution.
Variability
Body size, organ function, maturation, genotype and interacting drugs can explain some pharmacokinetic variability.
Sampling and estimation
Sparse and rich concentration measurements require suitable analysis methods, assay validation and transparent handling of missing or below-quantification observations.
Application and validation
External evaluation and uncertainty assessment are required before a population model informs clinical drug-monitoring decisions.
