Description
Curator's Comment:: description was created based on several sources, including: https://www.drugs.com/pro/balsalazide.html

Balsalazide, a prodrug that is enzymatically cleaved by bacterial azoreduction to release equimolar quantities of mesalamine (5-aminosalicylic acid or 5-ASA) in the colon, an anti-inflammatory drug. The mechanism of action of 5-ASA is unknown, but appears to be local to the colonic mucosa rather than systemic. Balsalazide is indicated for the treatment of mildly to moderately active ulcerative colitis. Most frequently reported adverse events are: headache, abdominal pain, diarrhea, nausea, vomiting, respiratory infection, and arthralgia. The use of orally administered antibiotics could, theoretically, interfere with the release of mesalamine in the colon.

Sample Use Guides

Three 750 mg COLAZAL capsules to be taken three times a day for a total daily dose of 6.75 grams for a duration of 8 weeks. Some patients in the clinical trials required treatment for up to 12 weeks.
Route of Administration: Oral
Mean equivalent doses (0.1 to 10 mM) of balsalazide (range, 6.3 +/- 1.5 to 16.7 +/- 1.3 microA/cm2) significantly stimulated (P < 0.001) secretion in rabbit distal ileum. The value for the effective dose that is half the maximal dose for secretion induced by 0.9 mM.
