Coma and Crystalluria: A Massive Primidone Intoxication Treated with Haemoperfusion

AbstractThe present paper describes a patient who was in danger of dying from a massive primidone overdose. She was comatose, hypotensive and in acute renal failure with crystalluria. Because of her clinical condition and high plasma primidone level (209 mg/1) haemoperfusion was instituted. Both the calculated drug clearances and the remarkable. improvement in the patient's clinical condition suggest that haemoperfusion was very effective.
