Cell-based in vitro models for predicting drug permeability

Area of Science:

• Pharmacology
• Drug Development
• Cell Biology

Background:

• In vitro cell models are crucial for early-stage drug development, providing reproducible and cost-effective methods to assess drug permeation.
• These models utilize immortalized cells grown in monolayers, maintaining physiological characteristics relevant to drug absorption.

Purpose of the Study:

• To review various in vitro cell-based models for predicting drug permeability across different administration routes.
• To discuss the in vitro-in vivo correlation of these models.

Main Methods:

• Comprehensive literature review of established intestinal, pulmonary, nasal, vaginal, rectal, ocular, and skin cell-based in vitro models.
• Analysis of the similarities between in vitro models and in vivo conditions for drug absorption.

Main Results:

• Identified key in vitro cell models for predicting drug permeability through various routes.
• Provided evidence that specific models may mimic distinct in vivo drug absorption pathways.

Conclusions:

• In vitro cell models are widely used for drug permeability and absorption evaluation.
• Further detailed studies are required to enhance the in vitro-in vivo correlation of these models with human data for optimized drug discovery and clinical development.
