Objective: The purpose of this study is to investigate the appropriate dose of quetiapine in clinical psychiatric diseases by examining the drug prescription dose in the elderly and insomnia group through an analysis of the tendency of quetiapine dose prescribed by psychiatric diagnosis.
Methods: Among the patients who had been taking outpatient treatment to the mental health department for about 7 years and 8 months from May 1, 2010 to December 31, 2017, 2,794 patients who were continuously taking quetiapine immediate-release form drugs were retrospectively tested. In addition, all subjects were classified into a total of four groups according to their maintenance dose, four mental diseases that most commonly prescribe quetiapine were selected and grouped, and further analyzed whether there was a difference in prescription capacity by age and comorbidities for the insomnia group.
Results: Prescription dose of quetiapine was found to be less than 50 mg in depressive disorders and insomnia, which is a relatively low dose prescribed compared to schizophrenia and bipolar disorder. In the case of insomnia, quetiapine prescribed in the elderly patient group was 30.03±9.14 mg, which was relatively high compared to the non-elderly group. And in the case of insomnia accompanied by depressive disorder, 50.28±11.41 mg was prescribed, more than 60% higher doses than that of primary insomnia.
Conclusion: In the case of primary insomnia, quetiapine dose prescribed in the elderly patient group is higher than that in the non-elderly patient group.
