Summary
This study developed stable propolis extract emulsions for topical use. Carrier viscosity did not impact polyphenol release, but temperature significantly affected stability, guiding storage conditions.
Area of Science:
- Pharmaceutical Sciences
- Formulation Development
- Topical Drug Delivery
Context:
- Carrier development is crucial for semisolid topical dosage forms.
- Rheological testing predicts storage stability.
- Soft propolis extract offers antimicrobial, antiviral, anti-inflammatory, and antioxidant benefits.
Purpose:
- To assess how carrier physicochemical properties influence in vitro release of active ingredients from a modeled dosage form.
- To validate carrier composition and formulation technologies for propolis extract delivery.
Summary:
- Stable semisolid emulsions with soft propolis extract were achieved using 3%-12% emulsifier.
- Emulsifier quantity affected viscosity but not polyphenol release rate.
- Temperature had a greater impact on extract release than the propolis concentration.
Impact:
- Findings guide the development of stable topical formulations with complex extracts.
- Understanding release kinetics informs optimal storage conditions for pharmaceutical preparations.
- This research supports efficient drug delivery systems by optimizing carrier characteristics.

01:05Bioavailability 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...
01:22Modified-Release Drug Delivery Systems: Drug Release Characteristics
Drug release from modified-release dosage forms is designed to achieve specific therapeutic effects by controlling the rate and extent of drug release. The classification of these drug release systems is based on key pharmacokinetic assumptions: drug disposition follows first-order kinetics, drug release is the rate-limiting step in absorption, and the released drug is rapidly and completely absorbed.There are four major models of drug release patterns. The first model is the slow zero-order...
