About this pathway

Background

Zuclopethixol is the cis(Z)-isomer of the racemic drug clopenthixol [Article:11499890]. It is a neuroleptic atypical antipsychotic that acts at the dopamine D1 and D2 receptors [Article:29144549]. It is not approved by the FDA for use in the USA, but is marketed in Canada and Europe for treatment of schizophrenia, [Article:30000827]. It is associated with acquired long QT, extrapyramidal symptoms, metabolic disturbances and neuroleptic malignant syndrome [Article:29144549].

Pharmacokinetics

Zuclopenthixol is converted by CYP2D6 to inactive metabolites zuclopenthixol sulfoxide and n-dealkyl zuclopenthixol [Articles:33000414, 20946203, 7820260, 3439463]. In vitro inhibition experiments also showed involvement of CYP3A4 although it was not clear which metabolites were formed [Article:20946203].
