Description and Uses
Diflunisal is more potent than aspirin but produces fewer side effects and has a biological half-life three to four times greater than that of aspirin. It is rapidly and completely absorbed on oral administration, with peak plasma levels being achieved within 2 to 3 hours of administration. It is highly bound (99%) to plasma proteins after absorption. Its elimination half-life is 8 to 12 hours, and it is excreted into urine primarily as glucuronide conjugates. The most frequently reported side effects include disturbances of the GI system (e.g., nausea, dyspepsia, and diarrhea), dermatological reactions, and CNS effects (e.g., dizziness and headache).
Salicylate; non-selective cyclo-oxygenase inhibitor; antipyretic; analgesic; anti- inflammatory.
