| | Abstract | The effect of charcoal haemoperfusion on the pharmacokinetics of diltiazem is described in a patient with severe clinical toxicity following acute overdose. The patient presented within 3 h following acute ingestion of multiple medications including sustained-release diltiazem. Routine resuscitation and supportive care were administered, but hypotension did not resolve despite intravenous fluids and infusions of calcium, adrenaline, noradrenaline and vasopressin. Multiple-doses of activated charcoal, haemodialysis and charcoal haemoperfusion were prescribed to expedite the elimination of diltiazem. The maximum diltiazem concentration (577 microg.l(-1)) was recorded 7 h post ingestion which was followed by an erratic and prolonged elimination phase. The maximum clearance of diltiazem due to haemoperfusion was calculated to be 19.4 and 15.1 ml.min(-1) at different times, equating to removal of approximately 1.5 mg diltiazem during 4 h of haemoperfusion. Haemoperfusion did not appear to remove sufficient diltiazem to recommend its routine use in the treatment of patients with acute diltiazem overdose. | | Language | eng | | Pub Type(s) | Case Reports Journal Article Research Support, Non-U.S. Gov't
