Area of Science:

• Pharmacokinetics
• Mathematical Modeling
• Drug Development

Background:

• Compartmental models are crucial for understanding drug behavior in the body.
• Estimating multiple-dose drug concentrations from single-dose data is essential for therapeutic drug monitoring.
• Non-linear models present challenges for precise confidence interval calculation.

Purpose of the Study:

• To develop and apply a conservative interval estimation procedure for multiple-dose drug concentrations.
• To provide confidence intervals for drug levels in a one-compartment open model.
• To offer extended tables to aid in the estimation procedure.

Main Methods:

• Parameter estimation from plasma concentration data after a single drug dose.
• Application of a conservative interval estimation procedure.
• Focus on the one-compartment open model with rapid intravenous injection.

Main Results:

• Successful estimation of compartmental model parameters from single-dose data.
• Generation of confidence intervals for multiple-dose drug concentrations.
• Provision of extended tables to support the interval estimation process.

Conclusions:

• The proposed conservative method offers a practical approach to confidence interval estimation for multiple-dose pharmacokinetics.
• This method is applicable to the one-compartment open model, enhancing its utility in drug studies.
• The provided tables facilitate the implementation of the estimation procedure in pharmacokinetic analyses.
