Description: Balsalazide is a prodrug of mesalazine which is linked to 4-aminobenzoyl-β-alanine via an azo bond. W/ the release of mesalazine, it reduces inflammation by inhibiting cyclooxygenase and leukotriene synthesis, thus blocking the formation of arachidonic acid in the colonic mucosa. Pharmacokinetics: Absorption: Time to peak plasma concentration: 1-2 hr (balsalazide); 9-10hr (mesalazine). Distribution: Plasma protein binding: Approx 99%. Metabolism: Undergoes bacterial azoreduction in the colon to 5-aminosalicylic acid (mesalazine, active), 4-aminobenzoyl-β-alanine (inert), and N-acetylated metabolites; 4-aminobenzoylalanine undergoes hepatic first-pass metabolism. Excretion: Mainly via faeces (approx 65%, as mesalazine, 4-aminobenzoyl-β-alanine or N-acetylated metabolites); urine (approx 25%, as N-acetylated metabolites); <1% via urine or faeces (as unchanged drug). Elimination half-life: 6-9 hr (as N-acetylated metabolites); approx. 1 hr (mesalazine).
A07EC04 - balsalazide ; Belongs to the class of aminosalicylic acid and similar antiinflammatory. Used in the treatment of intestinal inflammation.
