Abstract
Background: Gastric ulcer develops from imbalance of gastro-aggressive and protective factors. As existing drugs have adverse effects, use of natural products is in continuous expansion. In this study, we prepared nanoformulation with catechin and polylactide-co-glycolide to provide a sustained, controlled and targeted delivery. Materials & methods: Detailed characterization and toxicity study of nanoparticles were done on cells and Wistar rats. The comparative actions of free compound and nanocapsule were investigated in vitro and in vivo during treatment of gastric injury. Results: Nanocatechin improved bioavailability, reduced gastric damage at a significantly lower dose (2.5mg/kg) by safeguarding from reactive oxygen species, restored mitochondrial integrityanddownregulated MMP-9 and other inflammatory mediators. Conclusion: Nanocatechin is a better alternative for preventing and healing gastric ulcers.
