Oral Mucosa Models to Evaluate Drug Permeability

Area of Science:

• Pharmacology
• Drug Delivery
• Biomaterials

Background:

• The oral mucosa offers advantages for drug administration, including rapid absorption and bypassing first-pass metabolism.
• Significant interest exists in understanding drug permeability through this barrier for enhanced therapeutic outcomes.

Purpose of the Study:

• To review and identify effective ex vivo and in vitro models for assessing oral mucosal drug permeability.
• To highlight the need for standardized models in developing novel oral drug delivery systems.

Main Methods:

• Comprehensive literature review of existing ex vivo and in vitro models.
• Focus on models evaluating permeability of both conveyed and non-conveyed drugs.
• Analysis of model effectiveness and limitations for oral drug delivery research.

Main Results:

• Various ex vivo and in vitro models are utilized to study oral drug permeability.
• Existing models present limitations, indicating a need for standardization.
• Oral Mucosa Equivalents (OMEs) show potential as advanced models.

Conclusions:

• Effective models are essential for advancing oral drug delivery systems.
• Standardized models are required to overcome current research limitations.
• Oral Mucosa Equivalents (OMEs) represent a promising future direction for oral mucosal permeability studies.
