Lofepramine is a tricyclic antidepressant that is structurally similar to imipramine and is extensively metabolised to desipramine. In the absence of other major pharmacological effects it appears that its antidepressant activity stems from the facilitation of noradrenergic neurotransmission by uptake inhibition, and possibly by the additional facilitation of serotoninergic neurotransmission. The overall therapeutic efficacy of lofepramine is comparable to that of imipramine, amitriptyline, clomipramine, maprotiline and mianserin in patients with depression of varying severity, and coexisting anxiety. Lofepramine is a strong inhibitor of norepinephrine reuptake (Ki=5.4 nM) and a moderate inhibitor of serotonin reuptake (Ki=70 nM). It is a weak-intermediate level antagonist of the muscarinic acetylcholine receptors.Lofepramine is licensed for the treatment of depression in the United Kingdom.
