[Indoprofen in chronic intermittent peritoneal dialysis: effects in the clearance of small molecules and protein...

We studied the effects of indoprofen on urea and creatinine clearance and on protein loss in 6 patients submitted to intermittent peritoneal dialysis. The patients had no evidence of peritonitis. Dialysis fluid contained indoprofen (50 mg/l) or no drug. Mean protein loss into dialysis solution was 51.2 g without and 44.7 g with indoprofen (NS). Urea clearance was 33.3 and 33.6 ml/min and creatinine clearance 24.7 and 36.0 ml/min, respectively (NS). Levels of PGF2 alpha in the dialysate, measured in 2 subjects, were not affected by indoprofen. These results suggest that prostaglandins are not the main factors involved in control of urea and creatinine clearance and protein loss during intermittent peritoneal dialysis.
