Clozapine use in female geriatric patients with psychoses.
This study was undertaken to evaluate the clinical response of geriatric patients with psychoses to the atypical neuroleptic drug, clozapine. Records of patients over 60 years of age (n = 12, all female) who had received clozapine over a 30-month period from selected hospitals in Western Pennsylvania were reviewed. Among the six patients who were rapidly titrated (300 mg/day in 3 weeks), none are currently receiving clozapine, while four patients who received a slower titration and lower dosage (range, 25 mg/day to 300 mg/day; mean, 150 mg/day) remain clinically improved on stable doses of clozapine. Postural hypotension affected seven patients, and was the reason for discontinuation of clozapine in five patients. One patient experienced nonfatal agranulocytosis, and one subject experienced leukopenia. One patient died from causes unrelated to clozapine. This retrospective study suggests both a low-dose and slow-titration strategy for initiating clozapine among elderly patients, similar to the use of other psychotropic drugs in the elderly, as well as close attention to postural hypotension, agranulocytosis, and drug interactions.
