Abstract:Background and Objective: The H. pylori infection causes chronic inflammation and significantly
increases the risk of developing duodenal and gastric ulcer disease and gastric cancer. Infection
with H. pylori is the well-known risk factor for gastric cancer. It is highly desirable to develop a
delivery system that localizes the antibiotic at the site of infection to achieve bactericidal concentration
for a longer period of time. Thus, present work aimed to develop Concanavalin-A (Con-A) conjugated
gastro-retentive microspheres of polymethylmethacrylate (PMMA) and polyethylene oxide (PEO) containing
berberine hydrochloride (BBR) for the treatment of H. pylori infection.
Methods: Microspheres were prepared by solvent evaporation method and characterized by particles
size distribution, surface morphology, % drug entrapment and in vitro drug release in the simulated gastric
fluid. Optimized microspheres were conjugated with Con-A and further characterized for Con-A
conjugation efficiency, in vitro drug release and ex vivo mucoadhesive properties.
Results and Conclusion: Enhanced mucoadhesion (88±1.9%) was shown by Con-A conjugated microspheres
as compared with non-conjugated microspheres (14.5±3.6%). This significant difference
(p<0.05) in the mucoadhesion may be due to affinity of the Con-A towards glycoproteins of mucus
membrane of stomach. Attachment of lectin (Con-A) to the microspheres significantly enhanced the
mucoadhesiveness as well as also controlled the berberine release for 10 h study period. The preliminary
results from this study advised that Con-A conjugated PMMA and PEO microspheres could be
used to incorporate some more herbal drugs and may be used for oral administration against H. pylori in
the stomach.
