Abstract
This study was carried out to compare the efficacy of intravenous sodium valproate with intramuscular haloperidol in patients with acute mania. A total of 30 patients meeting DSM-IV criteria for acute manic episodes were enrolled. They were randomly assigned to 2 groups of 15 patients each. Both groups were treated twice daily with haloperidol (10 mg, intramuscular) and sodium valproate (500 mg, intravenous). The patients were assessed on days 1, 5, 9, and 13. Improvement in symptoms was assessed by reduction in the Young Mania Rating Scale (YMRS). Outcome criterions for analysis were latency of response and remission; additional drugs were required for sedation. At the end of the 2-week study period, overall response rate in both the groups was similar (P > .1). In comparison to haloperidol group, patients treated with sodium valproate showed faster response, and on day 5, significant reduction in YMRS score was observed in the group treated with sodium valproate (P < .05). Total amount of lorazepam was less in patients treated with sodium valproate. Extrapyramidal symptom episodes were observed in 60% of patients treated with haloperidol. Sodium valproate in the treatment of acute mania is as efficacious as haloperidol but provides a faster response. It is safer compared to haloperidol.
