Identification
- Summary
Diflunisal is an NSAID used to treat mild to moderate pain, inflammation, osteoarthritis, and rheumatoid arthritis.
- Generic Name
- Diflunisal
- DrugBank Accession Number
- DB00861
- Background
Diflunisal, a salicylate derivative, is a nonsteroidal anti-inflammatory agent (NSAIA) with pharmacologic actions similar to other prototypical NSAIAs. Diflunisal possesses anti-inflammatory, analgesic and antipyretic activity. Though its mechanism of action has not been clearly established, most of its actions appear to be associated with inhibition of prostaglandin synthesis via the arachidonic acid pathway. Diflunisal is used to relieve pain accompanied with inflammation and in the symptomatic treatment of rheumatoid arthritis and osteoarthritis.

Diflunisal is a nonsteroidal drug with analgesic, anti-inflammatory and antipyretic properties. It is a peripherally-acting non-narcotic analgesic drug. Habituation, tolerance and addiction have not been reported. Diflunisal is a difluorophenyl derivative of salicylic acid. Chemically, diflunisal differs from aspirin (acetylsalicylic acid) in two respects. The first of these two is the presence of a difluorophenyl substituent at carbon 1. The second difference is the removal of the 0-acetyl group from the carbon 4 position. Diflunisal is not metabolized to salicylic acid, and the fluorine atoms are not displaced from the difluorophenyl ring structure.
- Mechanism of action
The precise mechanism of the analgesic and anti-inflammatory actions of diflunisal is not known. Diflunisal is a prostaglandin synthetase inhibitor. In animals, prostaglandins sensitize afferent nerves and potentiate the action of bradykinin in inducing pain. Since prostaglandins are known to be among the mediators of pain and inflammation, the mode of action of diflunisal may be due to a decrease of prostaglandins in peripheral tissues.
Target Actions Organism AProstaglandin G/H synthase 2 inhibitorHumans UProstaglandin G/H synthase 1 inhibitorHumans - Absorption
Rapidly and completely absorbed following oral administration, with a bioavailability of 80-90%. Peak plasma concentrations are achieved 2 - 3 hours following oral administration.
- Volume of distribution
Not Available
- Protein binding
At least 98 to 99% of diflunisal in plasma is bound to proteins.
- Metabolism
Hepatic, primarily via glucuronide conjugation (90% of administered dose).
- Route of elimination
The drug is excreted in the urine as two soluble glucuronide conjugates accounting for about 90% of the administered dose. Little or no diflunisal is excreted in the feces.
- Half-life
8 to 12 hours

Improve decision support & research outcomesWith structured adverse effects data, including: blackbox warnings, adverse reactions, warning & precautions, & incidence rates. View sample adverse effects data in our new Data Library!Improve decision support & research outcomes with our structured adverse effects data.- Toxicity
Oral LD50 in rat, mouse, and rabbit is 392 mg/kg, 439 mg/kg, and 603 mg/kg, respectively. Symptoms of overdose include drowsiness, nausea, vomiting, diarrhea, hyperventilation, tachycardia, sweating, tinnitus, disorientation, stupor, and coma. As a monotherapy, the smallest dosage capable of causing death was reported as 15 grams.
Selective COX-2 inhibitors have been associated with increased risk of serious cardiovascular events (e.g. myocardial infarction, stroke) in some patients. Current data is insufficient to assess the cardiovascular risk of diflunisal. Short-term use does not appear to be associated with increased cardiovascular risk (except when used immediately following coronary artery bypass graft (CABG) surgery). Risk of GI toxicity including bleeding, ulceration and perforation. Risk of direct renal injury, including renal papillary necrosis. Severe hepatic reactions, including cholestasis and/or jaundice, have been reported. May cause rash or hypersensitivity syndrome.

Drug Interaction Integrate drug-drug
interactions in your softwareAbacavir Diflunisal may decrease the excretion rate of Abacavir which could result in a higher serum level. Abciximab The risk or severity of bleeding and hemorrhage can be increased when Diflunisal is combined with Abciximab. Acarbose Diflunisal may increase the hypoglycemic activities of Acarbose. Acebutolol Diflunisal may decrease the antihypertensive activities of Acebutolol. Aceclofenac The therapeutic efficacy of Diflunisal can be decreased when used in combination with Aceclofenac. - Food Interactions
