Pouch drug delivery systems for dermal and transdermal administration

Area of Science:

• Pharmaceutical Sciences
• Materials Science

Background:

• Dermal and transdermal drug delivery systems are crucial for effective treatment administration.
• Existing systems face challenges in drug permeation, stability, and patient compliance.

Purpose of the Study:

• To design and investigate a novel carrier system for enhanced dermal and transdermal drug delivery.
• To characterize the physicochemical properties and evaluate the efficacy of the new system.

Main Methods:

• Development of pouch drug delivery systems (PDDS) using high ethanol concentration, phospholipid, polymer, and water.
• Characterization of the PDDS matrix using electron microscopy, (31)P-NMR, and FTIR.
• Pharmacodynamic evaluation of PDDS with lidocaine, brotizolam, and ibuprofen in relevant models and non-irritancy testing on a skin model.

Main Results:

• The PDDS formed a structured matrix upon non-occluded application to the skin.
• Lidocaine PDDS demonstrated faster drying and enhanced dermal delivery compared to a clinical product.
• PDDS with brotizolam and ibuprofen showed prolonged hypnotic and antipyretic effects, respectively.
• The carrier system was found to be non-irritant.

Conclusions:

• The developed pouch drug delivery systems (PDDS) offer a promising platform for improved dermal and transdermal drug administration.
• The system's properties, including enhanced drug delivery and prolonged effects, support its potential for various therapeutic applications.
• The non-irritant nature of the PDDS further enhances its suitability for clinical use.
