Flunarizine is a selective calcium entry blocker with calmodulin binding properties and histamine H1 / dopamine D2 blocking activity. It is not available in the US but marketed in other countries for prophylaxis of a migraine, occlusive peripheral vascular disease, the vertigo of central and peripheral origin, motion sickness and as an adjuvant in the therapy of epilepsy. The drug is also investigated for the treatment of schizophrenia.

Carpipramine (Prazinil, Defekton) is an atypical antipsychotic used for the treatment of schizophrenia and anxiety in France and Japan. In addition to its neuroleptic and anxiolytic effects, carpipramine also has hypnotic properties. In september 2014 L'ANSM decided to withdraw the marketing of Prazinil (carpipramine).

Cyamemazine (Tercian), also known as cyamepromazine, is a typical antipsychotic drug of the phenothiazine class used primarily in the treatment of schizophrenia and psychosis-associated anxiety. Cyamemazine actually behaves like an atypical antipsychotic, due to its potent anxiolytic effects and lack of extrapyramidal side effects. Cyamemazine is used for the treatment of chronic psychotic states, anxiety, major depression.

Levosulpiride [RV 12309, L-sulpiride, levosulpride, Dislep® 25, Levopride®, Levopraid®] is a potent dopamine D2 receptor blocker that was originated by Ravizza Farmaceutici (now AbbVie). Levosulpiride is the levo enantiomer of sulpiride. The levo enantiomer shows better/similar pharmacological actions and lower incidence of toxic effects than both dextro as well as the racemic forms of the drug. Levosulpiride is marketed in Italy and South Korea, and is possibly available elsewhere in Europe and Asia. Levosulpiride does not appear to be available in North America. Levosulpiride is available as 25mg tablets, drops and in ampoules for parenteral administration. Generic versions of levosulpiride also appear to be available in some countries. Levosulpiride is primarily indicated in conditions like Anxiety, Depression, Gastro-esophageal reflux disease, Irritable bowel syndrome, Schizophrenia, Tourette's syndrome, dyspeptic syndrome, essential cephalgia, and can also be given in adjunctive therapy as an alternative drug of choice in Peptic ulcer, Vertigo.

Timiperone is a neuroleptic agent that was developed in Japan. Timiperone has a potent antipsychotic activity, which is comparable to other butyrophenones such as haloperidol (HAL). Timiperone has a five-eight-times higher affinity to dopamine receptors and a 15-times higher affinity to serotonin receptors than those of HAL. Clinical trials have suggested that TIM has a specific action against negative symptoms such as lack of initiative or blunted affect as well as positive symptoms such as delusions and hallucinations in schizophrenics.

Sediel (generic name: tandospirone citrate, marketed as Sediel in Japan) is a new type of antianxiety drug developed independently by Sumitomo Pharmaceuticals. It acts selectively on only the serotonin nerves in the brain that play an important part in the formation of anxiety and depression, and demonstrates antianxiety and anti-depression effects. Since it does not act on the other nerves that are so extensive in the brain, there is virtually no hypnotic or sedative effect, and the drug displays virtually no drug-dependence or side effects such as drowsiness and dizziness. Sediel has been on sale in Japan since December 1996, and is recognized for recognized as effective in the treatment of generalized anxiety disorders. Tandospirone acts as a potent and selective 5-HT1A receptor partial agonist. It was also investigated the usefulness of 5-HT1A agonists for enhancing some types of cognitive performance and possibly social and work function in patients with schizophrenia, and related to this was discovered, that tandospirone in combination with atypical antipsychotic drugs can improve cognitive function in Schizophrenia.

Zuclopenthixol is indicated the management of the manifestations of schizophrenia and other mental illnesses with disturbances in thinking, emotional reactions and behaviour. It is also used to treat the manic phase of manic depressive illness. Zuclopenthixol, a thioxanthene derivative, has high affinity for both dopamine D1 receptors and dopamine D2 receptors. Zuclopenthixol also has high affinity for α1-adrenergic and 5-HT2 receptors. Zuclopenthixol (CLOPIXOL®) is avavilable in the form of tablets and solution for intramuscular injections.

Nemonapride, benzamide derivative (YM-09151-2) is essentially a typical antipsychotic drug, similar in structure to sulpiride. This drug was manufactured by Yamanouchi Pharmaceuticals and released in Japan. The mechanism of action of nemonapride is not proven, but its unique antipsychotic effect arises from its selective binding to the dopamine D2 receptor family. Since nemonapride has high affinity for D3 and D4 dopamine receptors, it is conceivable that its effect on negative symptoms might result from blockade of these receptors. Animal studies have suggested that nemonapride has pharmacological features that are different from those of typical neuroleptics. The low extrapyramidal side effect profile of nemonapride treatment appears to coincide with the characteristic features of another benzamide derivative, remoxipride.

Spiperone (Spiroperidol; brand name: Spiropitan (JP)) is a typical antipsychotic and research chemical belonging to the butyrophenone chemical class. Spiperone is selective D2 dopamine receptor antagonist; α1B-adrenoceptor antagonist; mixed 5-HT2A/5-HT1 serotonin receptor antagonist. Additionally, spiperone was identified by compound screening to be an activator of Ca2+ activated Cl− channels (CaCCs), thus a potential target for therapy of cystic fibrosis. Spiperone is widely used as a pharmacological tool for studying neurotransmitter receptors.

Flupenthixol is a thioxanthene antipsychotic used in the treatment of schizophrenia and other psychoses, with the exception of mania and psychomotor hyperactivity due to an activating effect associated with this drug. It may also be employed as an antidepressant. Flupenthixol has a wide range of pharmacological actions. Flupenthixol blocks dopaminergic receptors, thus interfering with dopaminergic transmission in the brain. Flupenthixol also inhibits serotonin 5-HT, histamine H1, muscarinic and alpha-1 adrenergic receptors.
