BALSALAZIDE DISODIUM vs DIPENTUM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Prodrug that delivers mesalamine (5-aminosalicylic acid) to the colon; mesalamine inhibits cyclooxygenase and lipoxygenase pathways, reducing prostaglandin and leukotriene synthesis, and scavenges reactive oxygen species, thereby decreasing colonic inflammation.
Olsalazine is a prodrug that is activated in the colon by bacterial azoreductases to release two molecules of 5-aminosalicylic acid (mesalamine), which locally inhibits cyclooxygenase and lipoxygenase pathways, reducing prostaglandin and leukotriene production, and exerts anti-inflammatory effects in the colonic mucosa.
2.25 g (three 750 mg capsules) orally three times daily
500 mg orally twice daily, administered as two 250 mg capsules.

Balsalazide itself has a terminal elimination half-life of approximately 0.5–1 hour; the active moiety mesalamine has a terminal half-life of 5–10 hours, which may be prolonged in renal impairment.
Terminal elimination half-life of olsalazine is approximately 0.9 hours. The active metabolite, 5-ASA, has a half-life in the colon of 2-5 hours due to local retention; systemic half-life is short (0.6-1.4 hours).
Primarily excreted in feces via biliary elimination (approximately 90%) following conversion to mesalamine; renal excretion accounts for less than 10% of the dose as mesalamine and its metabolites.
Primarily renal (80%), with fecal/biliary excretion up to 20% as olsalazine and metabolites (mainly 5-ASA).
