Zotepine, with the formula (2-chloro-11-(2-dimethyl-amino-ethoxy)-dibenzo thiepin, is a neuroleptic drug. It was designed and synthesized by Fujisawa Pharmaceutical Co Ltd.[A31855] It has been used as an antipsychotic in Japan, India and some places in Europe like UK and Germany since 1980's.[A31857] Zotepine was never approved by the FDA. In 1993, it was classified as inactive drug substance (Status I, Type II) and in 1995 the FDA studied the manufacturing procedures of Zotepine tablets in Germany, but the status remained inactive.[L1082] When the analysis of antipsychotics was retaken in 2016 by the FDA, zotepine did not reach the threshold effect to be further studied.[L1313]. In the EMA, by 2015 it was under pharmacovigilance studies for the potential treatment of acute renal failure.[L1314]
Zotepine, like other atypical antipsychotics, is considered as the first-line treatment in newly diagnosed schizophrenia. It is usually thought to be an option of choice for managing acute schizophrenic episodes when discussion with the patient is not possible. Zotepine, as an atypical antipsychotic, is used in patients who are suffering unacceptable side effects from conventional antipsychotics or in relapse patients that were inadequately controlled.[T108] It is important to consider that the indications stated above are related to atypical antipsychotics, that zotepine is not currently FDA, Canada or EMA approved and that studies have not shown any additional benefit when compared with other approved atypical antipsychotics.[A31857] Schizophrenia is a chronic and severe mental disorder that affects how a person thinks, feels and behaves. It is usually marked for a loose reality perspective delineated by hallucinations, delusions and thought and movement disorders.[L1320]
