Olsalazine
Identification
- Summary
Olsalazine is an anti-inflammatory agent used in the treatment of inflammatory bowel disease and ulcerative colitis.
- Brand Names
- Dipentum
- Generic Name
- Olsalazine
- DrugBank Accession Number
- DB01250
- Background
Olsalazine is an anti-inflammatory drug used in the treatment of Inflammatory Bowel Disease and Ulcerative Colitis. Olsalazine is a derivative of salicylic acid. Inactive by itself (it is a prodrug), it is converted by the bacteria in the colon to mesalamine. Mesalamine works as an anti-inflammatory agent in treating inflammatory diseases of the intestines.

Olsalazine is an anti-inflammatory drug used in the treatment of Inflammatory Bowel Disease and Ulcerative Colitis. Olsalazine reduces the bowel inflammation, diarrhea (stool frequency), rectal bleeding, and abdominal pain. Olsalazine is thought to work like balsalazide, delivering mesalazine or 5-aminosalicylic acid past the small intestine to the large intestine to act on the site of disease.
- Mechanism of action
Orally administered olsalazine is converted to mesalamine which is thought to be the therapeutically active agent in the treatment of ulcerative colitis. The mechanism of action of mesalamine (and sulfasalazine) is unknown, but appears to be topical rather than systemic. Mucosal production of arachidonic acid (AA) metabolites, both through the cyclooxygenase pathways, i.e., prostanoids, and through the lipoxygenase pathways, i.e., leukotrienes (LTs) and hydroxyelcosatetraenoic acids (HETEs) is increased in patients with chronic inflammatory bowel disease, and it is possible that mesalamine diminishes inflammation by blocking cyclooxygenase and inhibiting prostaglandin (PG) production in the colon.
Target Actions Organism AThiopurine S-methyltransferase inhibitorHumans AInterferon gamma Not Available Humans - Absorption
After oral administration, olsalazine, has limited systemic bioavailability. 98-99% of the dose is converted to mesalamine (5-ASA) in the colon, which is absorbed slowly resulting in very high local concentrations in the colon.
- Volume of distribution
Not Available
- Protein binding
Olsalazine and olsalazine-S are more than 99% bound to plasma proteins. Mesalamine (5-ASA) is 74% bound to plasma proteins.
- Metabolism
Most (98 to 99%) of an oral dose is rapidly converted into two molecules of 5-aminosalicylic acid (5-ASA) by colonic bacteria and the low prevailing redox potential found in this environment. The conversion of olsalazine to mesalamine in the colon is similar to that of sulfasalazine, which is converted into sulfapyridine and mesalamine. Approximately 0.1% of an oral dose of olsalazine is metabolized in the liver to olsalazine-O-sulfate (olsalazine-S)

- Route of elimination
Approximately 0.1% of an oral dose of olsalazine is metabolized in the liver to olsalazine-O-sulfate (olsalazine-S).The remaining 5-ASA is partially acetylated and is excreted in the feces.
- Half-life
Olsalazine has an elimination half-life of 0.9 hours, however, olsalazine-S has a half-life of 7 days.
