Introduction

Physiological Parameters for PBPK Modeling (P³M) is a valuable resource for researchers and scientists working with pharmacokinetic and pharmacodynamic (PK/PD) models. The tool provides a unique dataset of human physiological parameters that are correlated with each other and vary according to interindividual differences in populations defined by gender, race, and age. In this article, we will delve into the world of P³M and explore its features, benefits, and applications in PBPK modeling.

What is PBPK Modeling?

PBPK modeling is a mathematical approach used to simulate the behavior of substances in the body. It takes into account the physiological and biochemical processes that occur in the body, such as absorption, distribution, metabolism, and excretion (ADME). PBPK models are used to predict the concentration of a substance in various tissues and organs, as well as its effects on the body. The models are particularly useful in the development of new drugs and in the assessment of the risks associated with exposure to environmental pollutants.

Physiological Parameters for PBPK Modeling

P³M provides a comprehensive dataset of physiological parameters that are essential for PBPK modeling. The dataset includes parameters such as:

Body weight: The weight of an individual, which is a critical factor in PBPK modeling.
Body surface area: The surface area of an individual's body, which is used to estimate the rate of metabolism and excretion.
Liver weight: The weight of the liver, which is a key organ in the metabolism of substances.
Kidney weight: The weight of the kidneys, which are responsible for the excretion of substances.
Blood flow: The rate at which blood flows through the body, which is essential for the distribution of substances.
Metabolic rate: The rate at which the body metabolizes substances, which is influenced by factors such as age, sex, and body weight.
