Colazide, also known by its generic name balsalazide, is a medication primarily used in the treatment of ulcerative colitis, a chronic condition characterized by inflammation of the colon and rectum. It belongs to a class of drugs known as aminosalicylates, which work by reducing inflammation in the colon, thereby helping to alleviate symptoms such as diarrhea, rectal bleeding, and abdominal pain associated with the condition. Colazide is designed to target the colon specifically, where it is broken down into its active form to exert its therapeutic effect with minimal systemic absorption. This targeted approach helps in minimizing potential side effects and makes Colazide an effective option for long-term management of ulcerative colitis. It is usually taken orally in capsule form.
