Ulcerative colitis (UC) is a persistent, idiopathic form of inflammatory bowel disease (IBD) marked by uninterrupted inflammation of the colon's mucosal lining, usually starting at the rectum and progressing proximally in a continuous manner. It manifests clinically with recurrent episodes of abdominal pain, bloody diarrhea, urgency, tenesmus, and weight loss. The precise cause of UC is still unknown; however, it is thought to arise from a multifactorial interaction involving genetic susceptibility, immune system dysregulation, disturbances in gut microbiota composition, and various environmental factors.

Double blinded
| Pentoxifylline | Drug | Pentoxifylline (PTX), a methylxanthine derivative and non-selective phosphodiesterase inhibitor, has been extensively studied for its anti-inflammatory and immunomodulatory actions. It inhibits TNF-α production at the transcriptional level and downregulates several inflammatory cytokines, including IL-1β, IL-6, and interferon-γ |
