Hypothesis
Can CPP-modified PLGA nanoparticles enhance ocular drug delivery and retention?
Conclusion
CPP-modified PLGA nanoparticles significantly improve ocular drug delivery, offering better bioavailability and prolonged retention in the eye.
Supporting Evidence
- CPP-modified nanoparticles showed a 13% increase in cumulative drug permeation.
- The Cmax of CPP-PLGA NPs was 4.19 μg/mL, a 38% increase compared to unmodified NPs.
- CPP modification improved cellular uptake of nanoparticles.
- Nanoparticles modified with CPP had better adhesion to ocular tissues.
- Encapsulation efficiency increased by 7.5% after adding CPP.
Takeaway
Scientists created tiny particles to help medicine stay in the eye longer, making it work better for eye problems.
Methodology
The study involved in vitro drug release, ex vivo corneal permeability tests, and in vivo studies in rabbits to assess drug retention and delivery efficiency.
Participant Demographics
New Zealand white rabbits, weight range 1.5–2.5 kg.
