Periciazine (INN), also known as pericyazine (BAN) or propericiazine, is a drug that belongs to the phenothiazine class of typical antipsychotics.

Periciazine is not approved for sale in the United States. It is commonly sold in Canada, Italy and Russia under the tradename Neuleptil and in United Kingdom and Australia under the tradename Neulactil.{{cite book|title=Pericyazine|work=Martindale: The Complete Drug Reference|publisher=The Royal Pharmaceutical Society of Great Britain|date=23 September 2011|access-date=2 November 2013|url=http://www.medicinescomplete.com/mc/martindale/current/7082-t.htm}}

Medical uses

The primary uses of periciazine include in the short-term treatment of severe anxiety or tension and in the maintenance treatment of psychotic disorders such as schizophrenia. There is insufficient evidence to determine whether periciazine is more or less effective than other antipsychotics. A 2014 systematic review compared periciazine with typical antipsychotics for schizophrenia:

Summary
On the basis of very low quality evidence it is not possible to determine the effects of periciazine in comparison with antipsychotics such as chlorpromazine or trifluoperazine for the treatment of schizophrenia. There is some evidence, however, that periciazine may be associated with a higher incidence of extrapyramidal side effects than other antipsychotics.

Periciazine has also been studied in the treatment of opioid dependence.{{cite journal | vauthors = ((Sivolap IuP)), Savchenkov VA | title = [The use of neuroleptics in treating opiate dependence] | language = ru | journal = Zhurnal Nevrologii I Psikhiatrii imeni S.S. Korsakova | volume = 99 | issue = 6 | pages = 29–34 | year = 1999 | pmid = 10441864 }}

Adverse effects

Periciazine is a rather sedating and anticholinergic antipsychotic, and despite being classed with the typical antipsychotics, its risk of extrapyramidal side effects is comparatively low.{{cite web|title=Approximate relative frequency (not intensity) of common adverse effects of antipsychotics (Table 8.21) [NB1]|date=February 2013|access-date=2 November 2013|url=http://etg.tg.com.au/conc/desktop/index.htm?id=75114e7800512079b341de7fb82c953c|work=eTherapeutic Guidelines complete|publisher=Therapeutic Guidelines Limited}}{{dead link|date=March 2018 |bot=InternetArchiveBot |fix-attempted=yes }} It has a relatively high risk of causing hyperprolactinaemia and a moderate risk of causing weight gain and orthostatic hypotension.

Synthesis

File:Pericyazine synthesis.svg

The final step in the synthesis involves the alkylation of 3-(2-cyanophenothiazin-10-yl)propyl 4-methylbenzenesulfonate, [https://pubchem.ncbi.nlm.nih.gov/compound/134990672 CID:134990672] (1) with 4-Piperidinol [5382-16-1] (2) giving Periciazine (3).
