Improving quercetin bioavailability through advanced drug delivery systems enhances its therapeutic potential. These systems boost pharmacological effects like antioxidant and anti-inflammatory actions for better clinical use.
Area of Science:
- Pharmacology
- Drug Delivery
- Nutraceuticals
Background:
- Quercetin is a key dietary flavonoid with diverse pharmacological activities.
- Poor gastrointestinal absorption and low bioavailability limit quercetin's clinical applications.
Purpose of the Study:
- To systematically review quercetin drug delivery systems.
- To summarize advancements in enhancing quercetin bioavailability and efficacy.
Main Methods:
- Conducted a systematic literature search across major scientific databases (PubMed, Web of Science, SciFinder, Google Scholar, CNKI).
- Synthesized findings on various quercetin delivery technologies.
Main Results:
- Delivery systems like microparticles, solid dispersions, encapsulation, phospholipid complexes, and hydrogels significantly improve quercetin bioavailability.
- Enhanced quercetin delivery systems show potent antibacterial, antioxidant, anti-inflammatory, and anti-cancer effects in vitro and in vivo.
Conclusions:
- Quercetin delivery systems are crucial for overcoming bioavailability challenges.
- These advanced systems hold promise for optimizing quercetin's therapeutic applications in clinical settings.
