Formula:

C14H11Cl2NO2

Basic Info

Diclofenac (sold under a number of trade names) is a nonsteroidal anti-inflammatory drug (NSAID) taken or applied to reduce inflammation and as an analgesic reducing pain in certain conditions. It is supplied as or contained in medications under a variety of trade names.
The name "diclofenac" derives from its chemical name: 2-(2,6-dichloranilino) phenylacetic acid. Diclofenac was first synthesized by Alfred Sallmann and Rudolf Pfister and introduced as Voltaren by Ciba-Geigy (now Novartis) in 1973.
In the United Kingdom, United States, India, and Brazil diclofenac may be supplied as either the sodium or potassium salt; in China, it is most often supplied as the sodium salt, while in some other countries it is only available as the potassium salt. It is available as a generic drug in a number of formulations, including diclofenac diethylamine, which is applied topically. Over-the-counter (OTC) use is approved in some countries for minor aches and pains and fever associated with common infections. As of 2015 the cost for a typical month of medication in the United States is 50 to 100 USD.
The drug's use in animals is controversial due to its toxicity which can rapidly kill scavenging birds that may eat dead animals. It has been banned for veterinary use in many countries.

12.1 Toxicity

  • Toxicity to fish: no data available
  • 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

AEROBIC: Diclofenac degradation in a freshwater inoculum from Lake Geifense, Swizterland and incubated for 37 days was found to be negligible(1). At low concentrations (3-35 uM), the compound was biodegraded when incubated in a river sediment consortia from the creek Muenzbach (Freiberg/Saxony), as indicated by the metabolite p-benzoquinone imine of 5-hydroxydiclofenac; concentrations of up to 260uM proved toxic(2). Diclofenac, present at 50 mg/L, reached 1.1% of its theoretical BOD in 75 days using a wastewater inoculum from the Jyvaskyla, Finland sewage treatment plant in the 301F Manometric respirometry test(3).

12.3 Bioaccumulative potential

An estimated BCF of 3 was calculated for diclofenac(SRC), using a log Kow of 4.51(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), provided the compound is not altered physically or chemically once released into the environment.

12.4 Mobility in soil

Using an agricultural soil from Corrstown, County Dublin, Ireland a log Koc of 2.39 was measured(1), corresponding to a Koc of 245(SRC). According to a classification scheme(2), this estimated Koc value suggests that diclofenac is expected to have moderate mobility in soil. The pKa of diclofenac is 4.15(3), indicating that this compound will exist almost entirely in the dissociated form in the environment and anions generally do not adsorb more strongly to organic carbon and clay than their neutral counterparts(4). Adsorption to sediments from Lake Greifensee, Switzerland was found to be negligible(5). When 500 ng/L diclofenac was mixed with one liter of lake water and 1 g sediment/L water, the aqueous phase showed no decrease in concentration following centrifugation and removal of sediment particles(5).

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.
