Dose-Response Modelling

Dose-response modelling quantitates pharmaceutical efficacy and toxicity dependencies on administered dose. Sigmoidal curves characterise threshold response below minimum dose and saturation above maximum. Hill coefficients quantitate curve steepness. EC50 and TD50 parameters define dose-response relationships. Population heterogeneity produces varied dose-response profiles.

Clinical trials employ dose-response design identifying optimal doses. Regulatory submissions incorporate dose-response justification. Combination therapy employs additive models characterising synergy. Narrow therapeutic index drugs require careful dose-response assessment. Post-approval monitoring confirms predicted dose-response relationships.
