Interestingly , diclofenac and flufenamic acid but not piroxicam significantly increased the extracellular superoxide anion production by neutrophils , and inhibition of nicotinamide adenine dinucleotide phosphate ( NADPH ) - oxidase activity with diphenyleneiodonium prevented the down - regulation of L - selectin by diclofenac .
