Are systemic levels of non steroidal anti inflammatory drugs relevant to acute upper gastrointestinal haemorrhage?

Abstract：

:It is uncertain as to the extent which gastrointestinal (GI) haemorrhage related to NSAIDs is due to a local, topical effect or to an action related to systemic absorption. We hypothesised that, should systemic drug concentrations be of importance, plasma levels of NSAIDs might be higher in patients who had developed GI haemorrhage, from controls who had not. Ten patients with GI haemorrhage, who had ingested piroxicam (and no other NSAID), within the preceding 64 h, at the same dosage and on no new medication for the past 14 days, had blood taken at presentation for measurement of piroxicam concentrations. Plasma piroxicam concentrations were measured in 19 community dwelling controls, matched for age +/- 8 years, gender, daily piroxicam dosage, and time from last dose as their respective index case. All had been taking piroxicam for at least 3 months, and none had experienced GI adverse effects. Median plasma piroxicam concentrations in patients at 8.27 micrograms/l, was higher than in controls at 5.06 micrograms/l. These results suggest that a systemic component, at least with piroxicam, may play a significant (though not necessarily exclusive) role in causing major gastrointestinal haemorrhage.
