Physiological Pharmacokinetic Models: Blood Flow-Limited Versus Diffusion-Limited Models

502
Physiological pharmacokinetic models, often called flow-limited or perfusion models, typically assume a swift drug distribution between tissue and venous blood, creating a rapid drug equilibrium. This premise is based on the idea that drug diffusion is extremely fast, and the cell membrane presents no barrier to drug permeation. In this scenario, where no drug binding occurs, the drug concentration in the tissue equals that of the venous blood leaving the tissue. This greatly simplifies the...

Passive Diffusion: Overview and Kinetics

1.8K
Passive diffusion is a critical process that allows small lipophilic drugs to cross the cell membrane along a concentration gradient. This mechanism's efficiency depends on four primary factors: the membrane's surface area, the drug's lipid-water partition coefficient, the concentration gradient, and the membrane's thickness.
When administered orally, drugs establish a substantial concentration gradient between the gastrointestinal (GI) lumen and the bloodstream, expediting...

Methods for Studying Drug Absorption: In vitro

844
In vitro experiments are crucial for understanding the transport and absorption of drugs through biological materials. These studies employ varied methods such as the diffusion cell method, the everted sac technique, and the everted ring technique.
The diffusion cell method uses a two-compartment cell, including a donor compartment with the drug solution, which simulates the environment where the drug is applied, and a receptor compartment with a buffer solution, which simulates the environment...

  • Literature review of mucus models (e.g., ex vivo, in vitro, in silico).
  • Analysis of experimental techniques used in mucus diffusion studies.
  • Comparative assessment of protocols focusing on nanomedicine diffusion.

Main Results:

  • Significant variability exists in mucus models and experimental methodologies.
  • Lack of standardization complicates the comparison and validation of nanomedicine diffusion data.
  • Different models and protocols yield diverse results, impacting nanomedicine candidate selection.

Conclusions:
