  • Lofepramine (Lopramine) hydrochloride is a potent tricyclic antidepressant and is extensively metabolised to Desipramine. The antidepressant activity of Lofepramine hydrochloride stems from the facilitation of noradrenergic neurotransmission by uptake inhibition. Lofepramine hydrochloride may also potentiate serotoninergic neurotransmission by inhibition of the neuronal uptake of serotonin and the enzyme tryptophan pyrrolase. Lofepramine hydrochloride has significant anxiolytic efficacy in addition to its antidepressant properties[1].
