Maprotiline-a double-blind study of a new tetracyclic antidepressant in severe depression.

A double-blind study was carried out comparing the antidepressant properties of maptotiline (a new tetracyclic antidepressant) and amitriptyline. Twenty-one hospitalized severely depressed patients, selected on the basis of clinical and psychometric criteria, completed the trial period of 28 days. The new drug was found to have an order of effectiveness similar to that of amitriptyline and both drugs were effective in agitated as well as retarded forms of depression. For both, the "day of effect", intended as the timing of sharp clinical improvement, tended to occur during the second week of treatment. Both drugs were well tolerated by most patients but one of the maprotiline patients presented a generalized rash which resolved after discontinuation of the drug. In conclusion, maprotiline is seen as an interesting addition to the group of major antidepressant drugs.
