Three groups of neurotic depressed patients were treated with amitriptyline, one group receiving the customary three daily doses, another a single dose in the morning, and the third a single dose at night. All three groups showed significant decrements of total scores on the Hamilton Scale for Depression and the Zung Self-Rating Depression Scale without significant differences. Patients taking the drug at night showed a lower incidence of side effects.
