Ulcerative colitis, an inflammatory disease of the colon, is prone to recurrence. Research into novel therapies for this condition is urgently required. The current investigation aims to ascertain the protective impact of microspheres loaded with mangiferin in acetic acid-induced ulcerative colitis (UC).
The formulation significantly reduced inflammatory alterations, ulcer activity scores, and oxidative stress. Colitis was induced by injecting 1 mL of a 4% acetic acid solution. In addition to a macroscopical and gross evaluation, colon samples were tested for catalase and glutathione (GSH) activity.
Microspheres loaded with mangiferin reduced the severity of ulcerative colitis caused by acetic acid, as indicated by improvements in weight loss, macroscopic score, ulcer area, and histological score.
This work emphasizes the use of dual-polymer microspheres to deliver mangiferin to the colon, allowing for pH-dependent and prolonged drug release. By increasing stability and site-specific activity, this method may be used to treat ulcerative colitis.
These findings suggest that enteric-coated microspheres loaded with mangiferin exhibit a protective effect against colon ulcers in rats and offer delayed-release properties compared to plain mangiferin.
