Antimicrobial Polymer-Based Hydrogels for the Intravaginal Therapies-Engineering Considerations

Area of Science:

• Pharmacology
• Biomaterials Science
• Drug Delivery

Background:

• Gynecological infections pose significant health challenges.
• Effective drug delivery systems are crucial for treating these infections.
• Hydrogels offer promising platforms for localized vaginal drug delivery.

Purpose of the Study:

• To review hydrogel systems for intravaginal drug delivery targeting gynecological infections.
• To discuss strategies for enhancing drug solubility and reservoir formation within hydrogels.
• To explore hydrogel designs for improved administration, distribution, and retention in the vaginal environment.

Main Methods:

• Review of literature on hydrogel systems for intravaginal drug delivery.
• Analysis of strategies including bigel systems, nano/microparticles, and polymer-based antimicrobial activity.
• Discussion of thermoresponsive and injectable hydrogel designs for administration.
• Examination of bioadhesion mechanisms for vaginal retention.

Main Results:

• Hydrogels can be engineered to deliver antibacterial, antifungal, and anti-Trichomonas vaginalis agents.
• Strategies like bigel systems and nano/microparticle incorporation improve hydrophobic drug solubility.
• Hydrogels can possess inherent antimicrobial properties or combine them with delivered drugs.
• Thermoresponsive and injectable hydrogels facilitate administration and distribution.
• Bioadhesion mechanisms are key to prolonging drug residence time.

Conclusions:

• Hydrogel systems represent a versatile platform for treating gynecological infections via intravaginal drug delivery.
• Advanced hydrogel designs enhance drug efficacy, administration, and retention.
• Further development of these systems holds significant promise for future gynecological therapies.
