Abstract

Introduction

The primary aim of this study was to develop an effective treatment strategy for periodontal diseases that maximizes therapeutic effects while minimizing systemic adverse effects. Specifically, the study focused on creating a xerogel-based localized drug delivery system for the slow release of doxycycline hyclate (DH) to treat periodontal disease.

Methods

Xerogels were prepared using the solvent casting method, with the solvent being evaporated slowly at ambient conditions. The prepared DH xerogels underwent comprehensive characterization to assess their in-silico compatibility, pharmacokinetics, and physicochemical properties. The properties studied included drying time and rate, thickness, moisture content, swelling index, organoleptic properties, scanning electron microscopy, FTIR spectroscopy, differential scanning calorimetry, drug release and kinetics, and antibacterial activity.

Results

In-silico studies demonstrated compatibility between the ingredients, indicating minimal adverse effects on the body. The analysis revealed hydrogen bonding between the drug and polymers, changing the drug's crystallization characteristics to an amorphous form. The release profiles of DH from the xerogels indicated a slow release, ranging from 29.42% to 66.30% over 10 hours, following the Hopfenberg model.

Conclusion

The findings of this study suggest that the formulated xerogels are well-suited for periodontal applications. The slow-release profile of DH from the xerogels offers a promising approach for localized treatment of periodontal disease, reducing the risk of systemic adverse effects. This data is valuable for dental practitioners and pharmaceutical formulators, providing a new avenue for enhancing periodontal disease treatment.
