Abstract:
A 43-year-old patient with mild heart failure attempted suicide by ingesting between 5000 and 7500 mg of captopril. Blood pressure oscillated around 100-120/50-75 mmHg and pulse rate showed no tendency to accelerate (75-100/min). The psychiatric examination showed no drug induced psychopathological symptoms. The calculated half-life of captopril was 4.4 h. Seven hours after ingestion of approximately 50 times the maximal therapeutic daily dose of captopril the serum concentration reached 20 micrograms/ml. The calculated amount of absorbed captopril was approximately 5400 mg. Atrial natriuretic factor (ANF) plasma levels were slightly elevated and showed no tendency to increase or to fall.
