The effect of adjunctive telmisartan treatment on psychopathology and cognition in patients with schizophrenia.
Summary
This is a 12-week, randomized, double-blinded, placebo-controlled trial of telmisartan 80 mg/day as an adjunctive to clozapine or olanzapine therapy, in 70 schizophrenia subjects to examine telmisartan's effect on glucose metabolism, weight, food intake, resting energy expenditure, and body composition. In addition, the study will examine insulin's effects on psychopathology and cognition.
Potential subjects will be identified by their clinicians at the Freedom Trail Clinic, or Massachusetts General Hospital. Approximately 70 subjects will be enrolled.
