Site-Targeted Drug Delivery Systems: Polymeric Carriers01:24

Site-Targeted Drug Delivery Systems: Polymeric Carriers

Polymeric carriers enhance targeted drug delivery by increasing efficacy while minimizing off-target effects. These carriers comprise a biodegradable polymeric backbone integrated with functional elements that enable targeting, improve physicochemical properties, and regulate drug release.Targeting MechanismsThe targeting ability of polymeric carriers is mediated by a homing device, which is a molecular recognition component designed to selectively bind to specific tissues or cells.

Insulin Formulations: Types and Delivery01:27

Insulin Formulations: Types and Delivery

Insulin preparations are categorized by their duration of action into short-acting and long-acting types. Two strategies are used to modify insulin's absorption and pharmacokinetic profile: slowing the absorption post-subcutaneous injection, or altering human insulin's amino acid sequence or protein structure. These changes retain the insulin's ability to bind to the insulin receptor, but alter its behavior in solution or after injection.
Short-acting insulins are divided into rapid-acting...

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.
