Older antidepressant spurs more suicidal thinking in men than newer medication

The largest clinical trial to date comparing an older, tricyclic antidepressant with a newer antidepressant of the selective serotonin reuptake inhibitor (SSRI) class has found that the emergence of suicidal thinking was almost 10 times more common in men taking the older drug than in those taking the newer medication.

The study also found that for men and women taking either medication, suicidal thinking was spread over the first six weeks of treatment, but peaked at roughly the fifth week before declining significantly after week six. Taking place at academic medical institutions across Europe, the trial, called Genome-Based Therapeutic Drugs for Depression--or GENDEP--gauged the responses to antidepressants of 811 persons ranging from 18 to 72 with depression.
