Lofepramine (Standard) is the analytical standard of Lofepramine. This product is intended for research and analytical applications. Lofepramine (Lopramine) is a modified tricyclic and orally active antidepressant. Lofepramine inhibits the uptake of Noradrenaline (NA) (HY-13715) and 5-hydroxytryptamine (5-HT) with IC50s of 2.7 µM and 11 µM, respectively. Lofepramine exerts its antidepressant activity by promoting noradrenergic neurotransmission. Lofepramine also enhances serotonergic neurotransmission by inhibiting neuronal uptake of 5-HT and tryptophan pyrrolase. Lofepramine exhibits significant anxiolytic properties. [1][2][3][4].
