Common NameClothiapine
DescriptionClothiapine, also known as entumin, belongs to the class of organic compounds known as dibenzothiazepines. Dibenzothiazepines are compounds containing a dibenzothiazepine moiety, which consists of two benzene connected by a thiazepine ring. Some sources regard clotiapine as a typical antipsychotic rather than atypical due to its high incidence of extrapyramidal side effects compared to the atypicals like clozapine and quetiapine, to which it is structurally related. Clotiapine (Entumine) is an atypical antipsychotic of the dibenzothiazepine chemical class. Clothiapine is a very strong basic compound (based on its pKa). Despite its profile of a relatively high incidence of extrapyramidal side effects it has demonstrated efficacy in treatment-resistant individuals with schizophrenia according to a number of psychiatrists with clinical experience with it, some weak clinical evidence supports this view too. It was first introduced in a few European countries (namely, Belgium, Italy, Spain and Switzerland), Argentina, Taiwan and Israel in 1970. This compound has been identified in human blood as reported by (PMID: 31557052 ). Clothiapine is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Clothiapine is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources.
