Lofepramine-d₃ 

Lofepramine-d₃ (Lopramine-d3) is the deuterium labeled Lofepramine. Lofepramine (Lopramine) is a potent tricyclic antidepressant and is extensively metabolised to Desipramine. The antidepressant activity of Lofepramine stems from the facilitation of noradrenergic neurotransmission by uptake inhibition. Lofepramine may also potentiate serotoninergic neurotransmission by inhibition of the neuronal uptake of serotonin and the enzyme tryptophan pyrrolase. Lofepramine has significant anxiolytic efficacy in addition to its antidepressant properties[1].

Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs^[1].
