Non-Compartmental Analysis

Non-compartmental analysis employs assumption-free pharmacokinetic methods quantitating drug exposure without predefined models. Area under curve calculation integrates plasma concentration over time. Clearance determination = dose / AUC. Volume of distribution = dose / C?. Half-life estimation enables dosing interval prediction.

Regulatory submissions employ non-compartmental analysis supporting pharmacokinetics. Bioavailability comparison between formulations uses AUC ratios. Population heterogeneity assessment identifies covariate effects. Statistical sophistication improves parameter estimation. Post-approval pharmacokinetics employs non-compartmental methods.
