<unk>  (brand names Kevopril, Kinupril, Adeprim, Quinuprine) is a tricyclic antidepressant (TCA) used in Europe for the treatment of depression. Pharmacologically,<unk>  acts in vitro as a strong muscarinic acetylcholine receptor antagonist (anticholinergic) and H1 receptor antagonist (antihistamine), moderate 5-HT2 receptor antagonist, and weak serotonin and norepinephrine reuptake inhibitor. It has negligible affinity for the α1-adrenergic, α2-adrenergic, β-adrenergic, or D2 receptor. Clinically,<unk>  is reported to be stimulating similarly to imipramine, desipramine, and demexiptiline. It can be inferred that its in vivo metabolites may have stronger effects on the reuptake of norepinephrine and/or serotonin than<unk>  itself.
