Olsalazine, sold under the brand name Dipentum among others, is a medication used to treat ulcerative colitis and Crohn’s disease.[1][2] It is used in people who cannot take sulfasalazine.[1] It is taken by mouth in the form of tablet or capsule.[3] If needed, contents of the capsule can be sprinkled on food.[3]

Side effects are uncommon but include numbess and a fast heart beat.[3] Other side effects may include diarrhea, nausea, heartburn, tiredness, and headache.[1] Caution is advised in kidney problems.[3] It is broken down into mesalazine (5-ASA) in the colon by which it acts.[2] 5-ASA than inhibits cyclooxygenase and lipoxygenase thereby reducing prostoglandin and leukotriene production.[1]

Olsalazine was approved for medical use in the United States in 1990.[1] It is available as a generic medication.[3] In the United Kingdom a months supply costs the NHS around £150 as of 2021.[3] In the United States this amount costs about 1,600 USD.[5]
