Abstract

ECG parameters in elderly depressed in-patients were assessed during routine despramine treatment. Significant changes (prolonged PR and PRS intervals and a decreased QTc interval) were found, related only to steady state concentrations of desipramine's major metabolite—2-hydroxy-desipramine. Potentially clinically significant changes developed in 40% of the patients. All serum drug concentrations were within therapeutic limits. Previous assurances about despiramines's cardiac safety in the elderly may need to be re-evaluated.
