Butyrophenone antipsychotics

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 for people with schizophrenia or related illnesses, who either forget or refuse to take the medication by mouth.

Droperidol (Inapsine, Droleptan, Dridol, Xomolix, Innovar [combination with fentanyl]) is an antidopaminergic drug used as an antiemetic (that is, to prevent or treat nausea) and as an antipsychotic. Droperidol is also often used as a rapid sedative in intensive-care treatment, and where "agitation aggression or violent behavior" are present.

Benperidol, sold under the trade name Anquil among others, is a typical antipsychotic primarily used to treat hypersexuality syndromes and can be used to treat schizophrenia. It is a highly potent butyrophenone derivative and is the most potent neuroleptic in the European market, with chlorpromazine equivalency as high as 75 to 100 (about 150 to 200% the potency per dose of haloperidol). It is sometimes prescribed to sex offenders as a condition of their parole, as an alternative to anti-androgen drugs such as cyproterone acetate.

Melperone (Bunil (PT), Buronil (AT, BE, CZ, DK, FI†, NL†, NO†, SE), Eunerpan (DE)) is an atypical antipsychotic of the butyrophenone chemical class, making it structurally related to the typical antipsychotic haloperidol. It first entered clinical use in 1960s.

Pipamperone (INN, USAN, BAN), sold under the brand name Dipiperon, is a typical antipsychotic of the butyrophenone family used in the treatment of schizophrenia and as a sleep aid for depression. It is or has been marketed under brand names including Dipiperon, Dipiperal, Piperonil, Piperonyl, and Propitan. Pipamperone was discovered at Janssen Pharmaceutica in 1961, and entered clinical trials in the United States in 1963.

Trifluperidol is a typical antipsychotic of the butyrophenone chemical class. It has general properties similar to those of haloperidol, but is considerably more potent by weight, and causes relatively more severe side effects, especially tardive dyskinesia and other extrapyramidal effects. It is used in the treatment of psychoses including mania and schizophrenia. It was discovered at Janssen Pharmaceutica in 1959.

Spiperone, also known as spiroperidol and sold under the brand name Spiropitan ((JP)) is a typical antipsychotic of the butyrophenone family related to haloperidol. It is approved for clinical use in Japan as a treatment for schizophrenia.

Bromperidol, sold under the brand names Bromidol and Impromen among others, is a typical antipsychotic of the butyrophenone group which is used in the treatment of schizophrenia. It was discovered at Janssen Pharmaceutica in 1966. An ester prodrug, bromperidol decanoate, is a long-acting form of bromperidol used as a depot injectable.

Moperone (Luvatren, since discontinued) is a typical antipsychotic of the butyrophenone class which is marketed in Japan for the treatment of schizophrenia. It is an antagonist for the D2 (Ki 0.7–1.9 nM), D3 (Ki 0.1–1 nM), and 5-HT2A (Ki 52 nM) receptors. It also has a high binding affinity for the sigma receptors.

Azaperone is a pyridinylpiperazine and butyrophenone neuroleptic drug with sedative and antiemetic effects, which is used mainly as a tranquilizer in veterinary medicine. It is uncommonly used in humans as an antipsychotic drug.

Timiperone, sold under the brand name Tolopelon, is a typical antipsychotic of the butyrophenone class which is marketed in Japan for the treatment of schizophrenia. It is similar in chemical structure to benperidol, but has a thiourea group instead of a urea group. It acts as an antagonist for the D2 and 5-HT2A receptors.

Spiramide (developmental code name AMI-193) is an experimental antipsychotic that acts as a selective 5-HT2A, 5-HT1A, and D2 receptor antagonist. It has negligible affinity for the 5-HT2C receptor. ==See also== Spirodecanone == References ==

Lenperone (Elanone-V) is a typical antipsychotic of the butyrophenone chemical class. It was first reported as an anti-emetic in 1974, and its use in treatment of acute schizophrenia was reported in 1975. Related early antipsychotic agents include declenperone and milenperone.

Fluanisone is a typical antipsychotic and sedative of the butyrophenone chemical class. It is used in the treatment of schizophrenia and mania. It is also a component (along with fentanyl) of the injectable veterinary formulation fentanyl/fluanisone (Hypnorm) where it is used for rodent analgesia during short surgical procedures.

Aceperone is a neuroleptic drug of the butyrophenone class. It is an α-noradrenergic blocking drug developed by Janssen Pharmaceutica in the 1960s.
