Assessment of Metformin as Adjuvant Therapy in Patients With Ulcerative Colitis

Study Purpose

Brief Summary: This is a randomized, controlled study evaluating metformin tablets administered daily for 8 weeks. The purpose of the study is to evaluate the efficacy and safety of metformin in the treatment of mild to moderately active ulcerative colitis. Disease activity will be measured using Mayo score for ulcerative colitis activity. Calculation of the score requires patients to undergo colonoscopy at the start of the study and at week 8.
