Hyaluronan-Based Hydrogel Hybrid Insulin Carriers-Preformulation Studies

Area of Science:

• Biomaterials science
• Drug delivery systems
• Tissue engineering

Background:

• Topical insulin delivery is crucial for managing diseased tissues and restoring metabolic balance.
• Hydrogels offer a promising platform for controlled drug release applications.
• Alginate-hyaluronan (ALG/HA) and hydroxypropyl methylcellulose-hyaluronan (HPMC/HA) are biocompatible polymers suitable for drug carriers.

Purpose of the Study:

• To develop and characterize novel hybrid hydrogel insulin carriers for topical application.
• To evaluate the pharmaceutical availability, rheological properties, and textural characteristics of the insulin-loaded hydrogels.
• To assess the potential of these carriers for sustained insulin release and therapeutic efficacy.

Main Methods:

• Synthesis of ALG/HA and HPMC/HA hybrid hydrogels.
• Incorporation of insulin into the hydrogel formulations.
• In vitro studies on insulin release kinetics and pharmaceutical availability.
• Rheological analysis (rotational and oscillatory) and texture profile analysis (TPA).

Main Results:

• The developed hybrid hydrogels demonstrated favorable rheological and textural properties for topical application.
• Sustained release of insulin was observed, indicating prolonged pharmaceutical availability.
• The formulations achieved a balance between ease of application and controlled release of the active substance.

Conclusions:

• Hybrid hydrogel insulin carriers based on ALG/HA and HPMC/HA are effective for topical delivery.
• These novel carriers ensure prolonged insulin release and possess suitable properties for therapeutic use.
• The findings support further preclinical and clinical investigations for advanced wound healing and metabolic disorder management.
