RT Journal Article SR Electronic T1 Insidon: a new antidepressant JF Drug and Therapeutics Bulletin JO Drug Ther Bull FD BMJ Publishing Group Ltd SP 36 OP 36 DO 10.1136/dtb.2.9.36 VO 2 IS 9 YR 1964 UL http://dtb.bmj.com/content/2/9/36.abstract AB Opipramol (Insidon - Geigy) is a dibenzazepine derivative which structurally resembles both perphenazine and imipramine. It is described as ‘an anti-depressant with a pronounced sedative effect.’ Its thymoleptic activity is regarded as insufficient for the treatment of severe depression but ‘eminently suitable for the treatment of those patients whose complaints are difficult to define objectively and who experience a mixed complex of symptoms arising from the emotional problems associated with their everyday lives.’ This seems to exclude only the seriously ill and the euphoric.
