Sertindole in the long-term treatment of schizophrenia.

This study assessed the safety and tolerability of sertindole in the long-term treatment of schizophrenia. An open-label, noncomparative, flexible-dose study was carried out in 11 European countries. Upon completion of an 8-week, haloperidol-referenced randomized clinical trial with sertindole, patients were offered sertindole maintenance treatment up to 18 months. In total, 294 patients were enrolled, of whom 237 (81%) had received sertindole and 57 (19%) had received haloperidol in the lead-in trial. The modal dose during the maintenance period was 16 mg/day. Patients showed therapeutic improvement indicated by significant decreases in the Positive And Negative Syndrome Scale and Clinical Global Impression 'severity-of-illness' scores. An adverse event was the primary reason for withdrawal in 13% of patients. The most common adverse events were fatigue and weight gain, both with incidences of 14%. The incidence of extrapyramidal symptoms was 18%, and 11% of the patients required anticholinergic medication. No statistically significant changes were observed in laboratory values or vital signs, but the mean serum prolactin levels decreased. The mean change in weight from baseline to the last assessment was 2.7 kg. The largest weight increase was observed in patients who were underweight at baseline. Long-term treatment with sertindole was safe and well tolerated, and patients showed clinical improvement beyond acute treatment.

Outcomes for Latin American versus White patients suffering from acute mania in a randomized, double-blind trial comparing olanzapine and haloperidol.

Data from a published double-blind randomized trial comparing olanzapine versus haloperidol in acute mania were used to address the response and tolerability of Latin American patients. Primary efficacy end point was the remission rate (Young Mania Rating Scale score

A 12-week, double-blind comparison of olanzapine vs haloperidol in the treatment of acute mania.

BACKGROUND: This randomized controlled trial compares the efficacy and safety of olanzapine vs haloperidol, as well as the quality of life of patients taking these drugs, in patients with bipolar mania. METHODS: The design consisted of 2 successive, 6-week, double-blind periods and compared flexible dosing of olanzapine (5-20 mg/d, n = 234) with haloperidol (3-15 mg/d, n = 219). RESULTS: Rates of remission (Young-Mania Rating Scale score of < or =12 and 21-item Hamilton Rating Scale for Depression score of < or =8 at week 6) were similar for olanzapine- and haloperidol-treated patients (52.1% vs 46.1%, respectively; P =.15). For the subgroup of patients whose index episode did not include psychotic features, rates of remission were significantly greater for the olanzapine group compared with the haloperidol group (56.7% vs 41.6%, P =.04). Relapse into an affective episode (mania and/or depression) occurred in 13.1% and 14.8% of olanzapine- and haloperidol-treated patients, respectively (P =.56). Switch to depression occurred significantly more rapidly with haloperidol than with olanzapine when using survival analysis techniques (P =.04), and significantly more haloperidol-treated patients experienced worsening of extrapyramidal symptoms, as indicated by several measures. Weight gain was significantly greater in the olanzapine group compared with the haloperidol group (2.82 vs 0.02 kg, P<.001). The olanzapine group had significant improvement in quality of life on several dimensions compared with the haloperidol group. CONCLUSIONS: These data suggest that olanzapine does not differ from haloperidol in achieving overall remission of bipolar mania. However, haloperidol carries a higher rate of extrapyramidal symptoms, whereas olanzapine is associated with weight gain.
