Clorotepine (aka octoclothepin or octoclothepine) is an antipsychotic from the tricyclic group derived from perathiepin. It was originally developed in 1965 and marketed in the Czech Republic by Spofa in or around 1971 for the treatment of schizophrenic psychosis. Clorotepine has a high affinity for the dopamine (D1, D2, D3, D4), receptors the serotonin 5-HT (2A, 2B, 2C, 6, 7) receptors, the alpha-adrenergic receptors (1A, 1B, 1D), and the histamine H1 receptors. In most instances, it acts as an antagonist (or inverse agonist). Clorotepine will also block the reuptake of norepinephrine by inhibiting the norepinephrine transporter.
