Summary
This study introduces a novel fibrin hydrogel system for sustained release of cis-platinum (CDDP). UV-irradiated carriers demonstrated slower degradation and controlled drug release, minimizing free drug levels.
Area of Science:
- Biomaterials Science
- Drug Delivery Systems
- Oncology
Context:
- Developing effective drug delivery systems is crucial for cancer therapy.
- Controlling the release kinetics of chemotherapeutic agents like cis-platinum (CDDP) can improve efficacy and reduce side effects.
- Fibrin hydrogels are biocompatible materials with potential for drug encapsulation.
Purpose:
- To develop and characterize a novel sustained release system for aqueous cis-platinum (CDDP).
- To evaluate the in vitro degradability of UV-irradiated fibrin hydrogel carriers.
- To assess the in vitro release profile of CDDP from the developed drug carriers.
Summary:
- Novel fibrin hydrogels were prepared and modified using UV irradiation to create gradually degradable drug carriers.
- Aqueous cis-platinum (CDDP) was loaded into the carriers under negative pressure.
- In vitro studies showed UV-irradiated carriers degraded over 10-15 days, significantly longer than non-UV-treated carriers (4-5 days).
- Sustained release of CDDP was observed, with most drug in a protein-binding form (>10 kDa) and minimal free CDDP.
Impact:
- This novel drug delivery system offers a promising approach for sustained and controlled release of cis-platinum.
- The UV-irradiation technique enhances carrier stability and modulates drug release.
- Further investigation into the antineoplastic efficacy of this system is warranted.
