MtoZ Biolabs provides a Physiologically Based Pharmacokinetic (PBPK) Modeling Service to support data-driven prediction of peptide absorption, distribution, metabolism, and excretion properties using mechanistic computational models. Our platform integrates physiological databases and physicochemical parameters to simulate in vivo behavior of peptide drug. This service offers predictive insights essential for optimizing peptide drug candidates, planning preclinical studies, and guiding translational decisions.
What Is Physiologically Based Pharmacokinetic (PBPK) Model?
Physiologically Based Pharmacokinetic modeling is a computational approach that describes how a compound moves through the body using mathematical representations of tissue compartments, physiological parameters, and biochemical processes. Instead of relying solely on empirical observations, PBPK integrates known biological features such as organ blood flow, tissue composition, metabolic capacity, and transport mechanisms. This structure allows PBPK models to simulate complex pharmacokinetic behavior and predict drug performance under various physiological or pathological conditions.

PBPK models enable researchers to forecast concentration-time profiles, predict exposure in different tissues, estimate oral bioavailability, and assess how intrinsic or extrinsic variations influence drug behavior. These models can also support decision making related to dosing, formulation design, drug interaction assessment, pediatric or geriatric extrapolation, and regulatory submissions.
