Zimelidine, an antidepressant, is a specific 5-hydroxytryptamine (5-HT) reuptake inhibitor, that can be used in treating phobic anxiety. It is very effective and can be tolerated well in elderly individuals. This serotonin transport inhibitor is less likely than other antidepressants to have cardiovascular side effects. Unlike other tricyclic antidepressants, Zimelidine might promote weight loss but not weight gain.
