Use of a thromboxane synthetase inhibitor, dazoxiben, during haemodialysis

1 We have assessed the thromboxane synthetase inhibitor, dazoxiben (UK 37248), during dialysis in a double-blind, placebo-controlled crossover study. 2 Thromboxane generation was markedly inhibited, and there was an increase in serum 6-keto prostaglandin F1 alpha levels during active treatment studies. 3 We were unable to demonstrate any reduction of platelet activation, or dialyser fibrin deposition, nor were heparin requirements altered by the drug. 4 Dazoxiben had no adverse effects.
