    Abstract:
    BACKGROUND: Results from open-label and placebo-controlled trials suggest that the selective serotonin reuptake inhibitors reduce impulsive aggressive behavior. The objective of this open-label study was to investigate whether citalopram treatment has anti-aggressive effect on impulsive aggressive subjects meeting DSM-IV criteria for a cluster B personality disorder or intermittent explosive disorder. METHOD: In this 8-week trial, subjects were initiated on 20 mg/day of citalopram and titrated up to 60 mg/day by the fourth week, if tolerated. The primary outcome measure was the Overt Aggression Scale-Modified (OAS-M), a scale used to quantify verbal and physical aggression, subjective irritability, and overt irritability. Secondary outcome measures included the Barratt Impulsiveness Scale and Buss-Durkee Hostility Inventory. RESULTS: Of 25 subjects enrolled, 20 completed the study. The mean daily dose was 45.5 mg, and citalopram was generally well tolerated. Statistically significant decreases were found in the OAS-M aggression scores (32.82 +/- 19.76 to 4.73 +/- 7.57, p =.000), subjective irritability scores (3.50 +/- 0.60 to 1.45 +/- 1.18, p =.000), and overt irritability scores (3.23 +/- 0.81 to 0.91 +/- 1.02, p =.000). CONCLUSION: These results suggest that citalopram is an effective treatment for reducing impulsive aggressive behavior.
