Bufexamac is a topically-active anti-inflammatory agent that inhibits the cyclooxygenase enzyme. In cutaneous and deep experimental inflammation, topical administration of bufexamac exerted a dose-related anti-inflammatory effect. In guinea pigs, bufexamax was shown to be more active than topical acetylsalicylic acid 5% or phenylbutazone 5% in delaying the local increase in temperature resulting from UV exposure. Bufexamac is unlikely to have any effect on wound healing.

The full mechanism of action is unclear. It is proposed that bufexamac acts similarly to other non-steroidal anti-inflammatory drugs to inhibit prostaglandin biosynthesis _in vitro_, via inhibiting cyclo-oxygenase (COX) enzymes. Systematically administered bufexamac may accumulate preferentially in the adrenal cortex of rats and may play a role in adrenal stimulation; however its topical anti-inflammatory action is likely to be independent of this effect.

Anti-inflammatory agents that are non-steroidal in nature. In addition to anti-inflammatory actions, they have analgesic, antipyretic, and platelet-inhibitory actions. They act by blocking the synthesis of prostaglandins by inhibiting cyclooxygenase, which converts arachidonic acid to cyclic endoperoxides, precursors of prostaglandins. Inhibition of prostaglandin synthesis accounts for their analgesic, antipyretic, and platelet-inhibitory actions; other mechanisms may contribute to their anti-inflammatory effects.

Method of application affects the extent of cutaneous absorption. Following rectal administration as suppositories, the systemic absorption was reported to be low.

Following topical administration of 5% bufexamac, the recovery in the urine was 3.5% of the applied dose within 144 hours. Studies in healthy volunteers receiving an oral dose of 125 to 500 mg indicate that an average of 80% of the total dose is excreted in the urine within 48 hours.
