Summary

The data on efficacy and tolerance from four (phase II and III) trials of quetiapine (Seroquel® or ICI 204,636) in a total of 1,461 patients with acute exacerbations of chronic or sub-chronic schizophrenia are briefly reviewed. Together, the results of these trials have demonstrated antipsychotic efficacy in comparison with placebo and equivalent efficacy to haloperidol. In spite of its short plasma elimination half-life, quetiapine is equally effective when given in twice-daily and three-time daily doses. The optimum dose is between 300 mg and 400 mg per day, and the main and most consistent adverse effect is sedation. It has a low extrapyramidal side effect liability and does not produce sustained elevations in plasma prolactin levels.
