Sulfate-conjugated methylprednisolone as a colon-targeted methylprednisolone prodrug with improved therapeutic properties against rat colitis

Methylprednisolone (MP) is one of the most widely used corticosteroids for the treatment of inflammatory bowel disease (IBD). However, systemic adverse effects of MP limit its availability for the disease. In present study, sulfate-conjugated methylprednisolone (MPS) was evaluated in vivo as a colon-targeted prodrug of MP and its therapeutic properties against 2,4,6-trinitrobenzenesulfonic acid-induced rat colitis were investigated.
