Amoxapine: once versus divided daily doses in neurotic and endogenous depression

In a six-week, double-blind clinical study of 35 hospitalized patients with the diagnoses of endogenous depression (18 patients) and depressive neuroses (17 patients), two dosage schedules of amoxapine were compared. While no statistically significant difference in overall therapeutic and adverse effects between the groups treated with single daily doses and divided daily doses were found by the end of the six weeks investigational period, onset of therapeutic effect was faster in the group treated with single daily doses. There was a significantly greater improvement in Anxiety-Somatization and Sleep Disturbance (HAM-D factors) in the group with depressive neurosis than in the group with endogenous depression.
