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 (Ki values of 67 nM, 330 nM, 130 nM, 340 nM, 460 nM for M1, M2, M3, M4 & M5 respectively).
