Definition

ChEBI: An organic sodium salt that is the disodium salt of 3,3'-azobis(6-hydroxybenzoic acid) (olsalazine). Effective in the treatment of inflammatory bowel disease and ulcerative colitis. Mechanism of action unknown, but appears to be topical

Preparation

5-Amino-2-chlorobenzoic acid diazotization, coupled with 2-Hydroxybenzoic acid, and then in a certain pressure and contains trace copper powder or Cupric oxide of Sodium hydroxide solution common heating (130 ~ 150 ℃).

brand name

Dipentum (UCB).

Clinical Use

Induction and maintenance of remission in ulcerative colitis

Metabolism

Olsalazine is broken down by the colonic bacterial flora into 2 molecules of 5-aminosalicylic acid (mesalazine).
The small amounts (1-2% of the dose or less) of intact olsalazine that are absorbed are excreted mainly in urine.
Approximately 0.1% of an oral dose of olsalazine is hepatically metabolised to olsalazine-O-sulfate (olsalazine-S), which has a half-life of 7 days.

Properties and Applications
