BALSALAZIDE DISODIUM vs DELZICOL
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.
Delzicol is a prodrug of mesalamine (5-aminosalicylic acid). It is converted to mesalamine in the colon by bacterial azoreduction. Mesalamine reduces inflammation in the colon by inhibiting prostaglandin production via cyclooxygenase inhibition and decreasing leukotriene synthesis via lipoxygenase pathway. It also scavenges reactive oxygen species and inhibits cytokine production.
2.25 g (three 750 mg capsules) orally three times daily
800 mg orally 3 times daily for ulcerative colitis; mesalamine 4 g retention enema once daily or 4 g foam once daily for proctosigmoiditis.

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.
The terminal elimination half-life of mesalamine is approximately 0.5-1.5 hours after oral administration. For the acetylated metabolite, it is 5-10 hours. The short half-life necessitates multiple daily dosing for sustained colonic anti-inflammatory effect.
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.
Approximately 40-50% of the absorbed dose is excreted renally as mesalamine (5-ASA) and its acetylated metabolite (N-Ac-5-ASA). Fecal excretion accounts for the remainder, including unabsorbed drug and biliary elimination.
