Description

Mesalazine (INN, BAN), also known as mesalamine (USAN) or 5-aminosalicylic acid (5-ASA), is an aminosalicylate anti-inflammatory drug used to treat inflammatory bowel disease, including ulcerative colitis, inflamed anus or rectum, and to maintain remission in Crohn's disease.
It is sold in an oral form to maintain remission in Crohn's disease, and as a rectal suppository and an enema for the lower bowel conditions. It is generic and sold under many brand names worldwide, and there are many formulations.
There is no data on use in pregnant women, but the drug does cross the placenta and is excreted in breast milk. The drug should not be used in children under two, people with kidney disease, or people who are allergic to aspirin.
Side effects are primary gastrointestinal but may include headache; GI effects include nausea, diarrhoea and abdominal pain. There have been scattered reports of various problems when the oral form is used, including problems caused by myelosuppression (leukopenia, neutropenia, agranulocytosis, aplastic anaemia, and thrombocytopenia, as well as hair loss, peripheral neuropathy, pancreatitis, liver problems, myocarditis and pericarditis, allergic and fibrotic lung reactions, lupus erythematosus-like reactions and rash (including urticaria), drug fever, interstitial nephritis and nephrotic syndrome, usually reversible on withdrawal. Very rarely, use of mesalazine has been associated with an exacerbation of the symptoms of colitis, Stevens Johnson syndrome and erythema multiforme.
Mesalazine is the active moiety of sulfasalazine, which is metabolized to sulfapyridine and mesalazine. It is also the active component of the prodrug balsalazide along with the inert carrier molecule 4-aminobenzoyl-beta-alanine.

  • Toxicity to daphnia and other aquatic invertebrates: no data available
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

ANAEROBIC: Mesalamine, present at 250 mg/L, produced 95.6% methane following a lag phase of 65 days using 2-nitrophenol-adapted sludge in batch assays conducted in 120 ml glass serum flasks and is considered completely biodegradable under anaerobic conditions(1). Mesalamine was completely degraded by a mesophilic sludge in 30 days (mesophilic granular sludge from a full-scale UASB reactor treating chemical industry wastewater of Shell Nederland Chemie at Moerdijk, The Netherlands, VSS concn - 25.5 g/L; specific aceticlastic activity - 0.3 COD/L/g VSS, 30°C) following a 20-day lag period(2). It was also completely degraded using a mesophilic floccular sludge from a lab-scale UASB reactor treating cattle manure wastewater - VSS concn 20.5 g/L; specific aceticlastic activity - 0.05 to 0.06 g COD/L/g VSS, so°C; however, specific incubation and acclimation details were not provided(2). Degradation using a thermophilic sludge was 100% in 48 days following a 34 day lag period - full-scale CSTR reactor digesting primary and secondary sludges at Kur'yanovskaya municipal aeration station, Moscow, Russia - VSS concn 20.5 g/L; specific aceticlastic activity 0.1 g COD/L g VSS, 55°C(2).

12.3 Bioaccumulative potential

An estimated BCF of 3 was calculated in fish for mesalamine(SRC), using an estimated log Kow of 0.98(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

12.4 Mobility in soil

Using a structure estimation method based on molecular connectivity indices(1), the Koc of mesalamine can be estimated to be 10(SRC). According to a classification scheme(2), this estimated Koc value suggests that mesalamine is expected to have very high mobility in soil. A predicted Kd value of 1.37 calculated for sludge samples in the UK, suggests that adsorption to sludge is low(3). Estimated pKa values of 2.09, 5.26 and 13.64(4) indicate that this compound will dissociate to the zwitterion form in the environment(SRC).

12.5 Other adverse effects

no data available

13.Disposal considerations

13.1 Disposal methods

Product

The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
