Pharmacokinetic-Pharmacodynamic Relationship

Pharmacokinetic-pharmacodynamic relationship quantitates drug exposure-response dependencies guiding dose selection. Exposure thresholds identify minimum levels producing benefit. Toxic thresholds define maximum tolerated exposure. Hill coefficients quantitate curve steepness. Population heterogeneity produces varied dose-response profiles.

Regulatory submissions incorporate dose-response justification. Biomarker assessment predicts individual responses. Therapeutic drug monitoring guides dose optimisation. Clinical outcomes correlate with exposures. Post-approval monitoring confirms predicted relationships.
