• Drug Groups: approved
• Description: An anti-inflammatory agent, structurally related to the salicylates, which is active in inflammatory bowel disease. It is considered to be the active moiety of sulphasalazine. (From Martindale, The Extra Pharmacopoeia, 30th ed)
• Indication: For the treatment of active ulcerative proctitis.
• Pharmacology: Mesalazine (INN, BAN), also known as Mesalamine (USAN) or 5-aminosalicylic acid (5-ASA), is an anti-inflammatory drug used to treat inflammation of the digestive tract (Crohn's disease) and mild to moderate ulcerative colitis. Mesalazine is a bowel-specific aminosalicylate drug that is metabolized in the gut and has its predominant actions there, thereby having fewer systemic side effects. As a derivative of salicylic acid, 5-ASA is also an antioxidant that traps free radicals, which are potentially damaging by-products of metabolism.
• Toxicity: Oral, mouse: LD₅₀ = 3370 mg/kg; Oral, rat: LD₅₀ = 2800 mg/kg; Skin, rabbit: LD₅₀ = >5 gm/kg. There have been no documented reports of serious toxicity in man resulting from massive overdosing with mesalamine. Under ordinary circumstances, mesalazine absorption from the colon is limited.
• Affected Organisms: Humans and other mammals
• Biotransformation: Rapidly and extensively metabolized, mainly to N-acetyl-5-ASA (Ac-5-ASA) in the intestinal mucosal wall and the liver. Ac-5-ASA is further acetylated (deactivated) in at least 2 sites, the colonic epithelium and the liver.
• Absorption: 20 to 30% absorbed following oral administration. 10 to 35% absorbed from the colon (rectal suppository) - extent of absorption is determined by the length of time the drug is retained in the colon.
• Half Life: The mean elimination half-life was 5 hours for 5-ASA and six hours for N-acetyl-5-ASA following the initial dose. At steady state, the mean elimination half-life was seven hours for both 5-ASA and N-acetyl-5-ASA.
• Protein Binding: About 80% of N-Ac-5-ASA is bound to plasma proteins, whereas 40% of mesalamine is protein bound.
• Elimination: Approximately 28% of the mesalamine in Asacol tablets is absorbed after oral ingestion, leaving the remainder available for topical action and excretion in the feces.; It is excreted mainly by the kidney as N-acetyl-5-aminosalicylic acid.

Research Area: Inflammation
Biological Activity:
Mesalamine (Lialda, Apriso) is an anti-inflammatory compound used to treat inflammation of the digestive tract ulcerative colitis and mild-to-moderate Crohn’s disease. Mesalamine (Lialda, Apriso) is a bowel-specific aminosalicylate drug that acts locally in the gut and has its predominant actions there, thereby having few systemic side effects. As a derivative of salicylic acid, 5-ASA is also thought to be an antioxidant that traps free radicals, which are potentially damaging byproducts of metabolism. [1]
