Platelet glycoprotein IIb/IIIa inhibition with eptifibatide: prolongation of inhibition of aggregation in acute renal failure and reversal with hemodialysis.

We report the time course to the restoration of normal platelet aggregation in three patients who were treated with eptifibatide in the setting of severe renal failure. There was prolonged platelet inhibition in the first patient who developed acute renal failure. The second patient with acute on chronic renal failure developed an intracerebral hemorrhage. Normal platelet aggregation was restored after acute hemodialysis. In a third patient with end-stage renal disease, platelet function returned to the normal range following hemodialysis. There is a prolonged time course to the restoration of normal platelet aggregation in patients with severe renal dysfunction who are treated with eptifibatide. Acute renal hemodialysis may reverse the inhibitory effect of eptifibatide on platelet aggregation in these patients. Copyright 2003 Wiley-Liss, Inc.
