Bioavailability Enhancement: Drug Stability Enhancement and GI Retention01:05

Bioavailability Enhancement: Drug Stability Enhancement and GI Retention

Improving a drug's stability in the gastrointestinal (GI) tract is paramount for enhancing its bioavailability and therapeutic effectiveness. Various strategies are employed to protect the drug from the harsh gastric milieu and to ensure its release and absorption at the desired site within the GI tract.Polymer coatings are one such method used to shield drugs from the stomach's acidic environment. By preventing premature drug release, these coatings improve the bioavailability of unstable...

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. Monoclonal...

Area of Science:

  • Pharmaceutical Sciences
  • Drug Delivery Systems
  • Materials Science

Background:

  • Improving topical ibuprofen efficacy requires enhanced delivery systems.
  • Cyclodextrins (Cd) offer solubilization and stabilization.
  • Non-ionic surfactant vesicles (NSVs) enhance skin penetration and tolerability.

Purpose of the Study:

  • To develop and characterize a novel ibuprofen delivery system.
  • To enhance ibuprofen's therapeutic efficacy in topical formulations.
  • To combine ibuprofen-β-cyclodextrin (βCd) complexes with NSVs.

Main Methods:

  • Phase solubility studies to evaluate ibuprofen-βCd complexation.
  • Co-lyophilization to prepare solid ibuprofen-βCd complexes.
  • Characterization using FTIR, DSC, size, zeta potential, stability, entrapment, and release studies.

Main Results:

  • Successful formation of ibuprofen-βCd complexes.
  • Incorporation of complexes into Tween 20/Cholesterol NSVs.
  • Optimized ibuprofen-βCd-NSV system demonstrated superior in vitro drug permeation compared to plain ibuprofen suspension.

Conclusions:

  • The developed ibuprofen-βCd-NSV system effectively enhances topical drug delivery.
  • This novel system improves ibuprofen permeation, offering potential for increased therapeutic efficacy.
  • The combination of βCd complexation and NSVs is a promising strategy for topical drug formulation.
