Perospirone (Lullan) is an atypical antipsychotic of the azapirone family. [1] It was introduced in Japan by Dainippon Sumitomo Pharma in 2001 for the treatment of schizophrenia and acute cases of bipolar mania. [3] [4]
Its primary uses are in the treatment of schizophrenia and bipolar mania. [3] [4]
In a clinical trial that compared it to haloperidol in the treatment of schizophrenia it was found to produce significantly superior overall symptom control. [5] In another clinical trial perospirone was compared with mosapramine and produced a similar reduction in total PANSS score, except with respect to the blunted affect part of the PANSS negative score, in which perospirone produced a significantly greater improvement. [6] In an open-label clinical trial comparing aripiprazole with perospirone there was no significant difference between the two treatments discovered in terms of both efficacy and tolerability. [7] In 2009 a clinical trial found that perospirone produced a similar reduction of PANSS score than risperidone and the extrapyramidal side effects was similar in both frequency and severity between groups. [8]
A meta-analysis published in 2013 found that it is statistically significantly less efficacious than other second-generation antipsychotics. [9]
Has a higher incidence of extrapyramidal side effects than the other atypical antipsychotics, but still less than that seen with typical antipsychotics. [1] [10] A trend was observed in a clinical trial comparing mosapramine with perospirone that favoured perospirone for producing less prominent extrapyramidal side effects than mosapramine although statistical significant was not reached. [6] It may produce less QT interval prolongation than zotepine, as in one patient who had previously been on zotepine switching to perospirone corrected their prolonged QT interval. [11] It also tended to produce less severe extrapyramidal side effects than haloperidol in a clinical trial comparing the two (although statistical significance was not reached). [5]
The British National Formulary recommends a gradual withdrawal when discontinuing antipsychotics to avoid acute withdrawal syndrome or rapid relapse. [12] Symptoms of withdrawal commonly include nausea, vomiting, and loss of appetite. [13] Other symptoms may include restlessness, increased sweating, and trouble sleeping. [13] Less commonly there may be a felling of the world spinning, numbness, or muscle pains. [13] Symptoms generally resolve after a short period of time. [13]
There is tentative evidence that discontinuation of antipsychotics can result in psychosis. [14] It may also result in reoccurrence of the condition that is being treated. [15] Rarely tardive dyskinesia can occur when the medication is stopped. [13]

Antipsychotics, previously known as neuroleptics and major tranquilizers, are a class of psychotropic medication primarily used to manage psychosis, principally in schizophrenia but also in a range of other psychotic disorders. They are also the mainstay, together with mood stabilizers, in the treatment of bipolar disorder. Moreover, they are also used as adjuncts in the treatment of treatment-resistant major depressive disorder.
Haloperidol, sold under the brand name Haldol among others, is a typical antipsychotic medication. Haloperidol is used in the treatment of schizophrenia, tics in Tourette syndrome, mania in bipolar disorder, delirium, agitation, acute psychosis, and hallucinations from alcohol withdrawal. It may be used by mouth or injection into a muscle or a vein. Haloperidol typically works within 30 to 60 minutes. A long-acting formulation may be used as an injection every four weeks by people with schizophrenia or related illnesses, who either forget or refuse to take the medication by mouth.
The atypical antipsychotics (AAP), also known as second generation antipsychotics (SGAs) and serotonin–dopamine antagonists (SDAs), are a group of antipsychotic drugs largely introduced after the 1970s and used to treat psychiatric conditions. Some atypical antipsychotics have received regulatory approval for schizophrenia, bipolar disorder, irritability in autism, and as an adjunct in major depressive disorder.
Ziprasidone, sold under the brand name Geodon among others, is an atypical antipsychotic used to treat schizophrenia and bipolar disorder. It may be used by mouth and by injection into a muscle (IM). The IM form may be used for acute agitation in people with schizophrenia.
Olanzapine, sold under the brand name Zyprexa among others, is an atypical antipsychotic primarily used to treat schizophrenia and bipolar disorder. For schizophrenia, it can be used for both new-onset disease and long-term maintenance. It is taken by mouth or by injection into a muscle.
Perphenazine is a typical antipsychotic drug. Chemically, it is classified as a piperazinyl phenothiazine. Originally marketed in the United States as Trilafon, it has been in clinical use for decades.
Aripiprazole, sold under the brand names Abilify and Aristada, among others, is an atypical antipsychotic. It is primarily used in the treatment of schizophrenia and bipolar disorder; other uses include as an add-on treatment in major depressive disorder and obsessive–compulsive disorder (OCD), tic disorders, and irritability associated with autism. Aripiprazole is taken by mouth or via injection into a muscle. A Cochrane review found low-quality evidence of effectiveness in treating schizophrenia.
Amisulpride is an antiemetic and antipsychotic medication used at lower doses intravenously to prevent and treat postoperative nausea and vomiting; and at higher doses by mouth to treat schizophrenia and acute psychotic episodes. It is sold under the brand names Barhemsys and Solian, Socian, Deniban and others. At very low doses it is also used to treat dysthymia.
Sulpiride, sold under the brand name Dogmatil among others, is an atypical antipsychotic medication of the benzamide class which is used mainly in the treatment of psychosis associated with schizophrenia and major depressive disorder, and is sometimes used in low dosage to treat anxiety and mild depression. Sulpiride is commonly used in Asia, Central America, Europe, South Africa and South America. Levosulpiride is its purified levo-isomer and is sold in India for similar purposes. It is not approved in the United States, Canada, or Australia. The drug is chemically and clinically similar to amisulpride.
Zotepine is an atypical antipsychotic drug indicated for acute and chronic schizophrenia. It has been used in Germany since 1990 and Japan since 1982.
Extrapyramidal symptoms (EPS) are symptoms that are archetypically associated with the extrapyramidal system of the brain's cerebral cortex. When such symptoms are caused by medications or other drugs, they are also known as extrapyramidal side effects (EPSE). The symptoms can be acute (short-term) or chronic (long-term). They include movement dysfunction such as dystonia, akathisia, parkinsonism characteristic symptoms such as rigidity, bradykinesia, tremor, and tardive dyskinesia. Extrapyramidal symptoms are a reason why subjects drop out of clinical trials of antipsychotics; of the 213 (14.6%) subjects that dropped out of one of the largest clinical trials of antipsychotics, 58 (27.2%) of those discontinuations were due to EPS.
Asenapine, sold under the brand name Saphris among others, is an atypical antipsychotic medication used to treat schizophrenia and acute mania associated with bipolar disorder as well as the medium to long-term management of bipolar disorder.
Iloperidone, commonly known as Fanapt and previously known as Zomaril, is an atypical antipsychotic for the treatment of schizophrenia.
Lurasidone, sold under the brand name Latuda among others, is an antipsychotic medication used to treat schizophrenia and bipolar disorder. It is taken by mouth.
Pimavanserin, sold under the brand name Nuplazid, is an atypical antipsychotic which is approved for the treatment of Parkinson's disease psychosis. Unlike other antipsychotics, pimavanserin is not a dopamine receptor antagonist, but rather is a selective inverse agonist of the serotonin 5-HT2A receptor.
Pomaglumetad (LY-404,039) is an amino acid analog drug that acts as a highly selective agonist for the metabotropic glutamate receptor group II subtypes mGluR2 and mGluR3. Pharmacological research has focused on its potential antipsychotic and anxiolytic effects. Pomaglumetad is intended as a treatment for schizophrenia and other psychotic and anxiety disorders by modulating glutamatergic activity and reducing presynaptic release of glutamate at synapses in limbic and forebrain areas relevant to these disorders. Human studies investigating therapeutic use of pomaglumetad have focused on the prodrug LY-2140023, a methionine amide of pomaglumetad (also called pomaglumetad methionil) since pomaglumetad exhibits low oral absorption and bioavailability in humans.
Tiospirone (BMY-13,859), also sometimes called tiaspirone or tiosperone, is an atypical antipsychotic of the azapirone class. It was investigated as a treatment for schizophrenia in the late 1980s and was found to have an effectiveness equivalent to those of typical antipsychotics in clinical trials but without causing extrapyramidal side effects. However, development was halted and it was not marketed. Perospirone, another azapirone derivative with antipsychotic properties, was synthesized and assayed several years after tiospirone. It was found to be both more potent and more selective in comparison and was commercialized instead.
Clocapramine, also known as 3-chlorocarpipramine, is an atypical antipsychotic of the iminostilbene class which was introduced in Japan in 1974 by Yoshitomi for the treatment of schizophrenia. In addition to psychosis, clocapramine has also been used to augment antidepressants in the treatment of anxiety and panic.
Brilaroxazine, also known as oxaripiprazole, is an investigational atypical antipsychotic which is under development by Reviva Pharmaceuticals for the treatment of neuropsychiatric and inflammatory disorders. It has currently completed the first of two phase III clinical trials for schizophrenia. Reviva Pharmaceuticals also intends to investigate brilaroxazine for the treatment of bipolar disorder, major depressive disorder, attention deficit hyperactivity disorder (ADHD), irritability in autism, tics, psychosis/agitation associated with Alzheimer's disease, Parkinson's disease psychosis, as well as the inflammatory disorders pulmonary arterial hypertension (PAH), idiopathic pulmonary fibrosis (IPF), and psoriasis. The FDA granted brilaroxazine orphan drug designation for the treatment of PAH and IPF.
Aripiprazole lauroxil, sold under the brand name Aristada, is a long-acting injectable atypical antipsychotic that was developed by Alkermes. It is an N-acyloxymethyl prodrug of aripiprazole that is administered via intramuscular injection once every four to eight weeks for the treatment of schizophrenia. Aripiprazole lauroxil was approved by the U.S. Food and Drug Administration (FDA) on 5 October 2015.
Withdrawal of antipsychotic drugs after long-term therapy should always be gradual and closely monitored to avoid the risk of acute withdrawal syndromes or rapid relapse.
