Trifluoperazine, marketed under the brand name Stelazine among others, is a typical antipsychotic primarily used to treat schizophrenia. [3] It may also be used short term in those with generalized anxiety disorder but is less preferred to benzodiazepines. [3] It is of the phenothiazine chemical class. It was approved for medical use in the United States in 1959. [4]
Trifluoperazine is an effective antipsychotic for people with schizophrenia condition. [5] There is low-quality evidence that trifluoperazine increases the chance of being improved when compared to placebo when people are followed up for 19 weeks. [5] There is low-quality evidence that trifluoperazine reduces the risk of relapse when compared with placebo when people are followed for 5 months. [5] As of 2014 there was no good evidence for a difference between trifluoperazine and placebo with respect to the risk of experiencing intensified symptoms over a 16-week period nor in reducing significant agitation or distress. [5]
There is no good evidence that trifluoperazine is more effective for schizophrenia than lower-potency antipsychotics like chlorpromazine, chlorprothixene, thioridazine and levomepromazine, but trifluoperazine appears to cause more adverse effects than these drugs. [6]
It appears to be effective for people with generalized anxiety disorder but the benefit–risk ratio was unclear as of 2005. [7]
It has been experimentally used as a drug to kill eukaryotic pathogens in humans. [8]
Its use in many parts of the world has declined because of highly frequent and severe early and late tardive dyskinesia, a type of extrapyramidal symptom. The annual development rate of tardive dyskinesia may be as high as 4%.[ citation needed ]
A 2004 meta-analysis of the studies on trifluoperazine found that it is more likely than placebo to cause extrapyramidal side effects such as akathisia, dystonia, and Parkinsonism. [9] It is also more likely to cause somnolence and anticholinergic side effects such as red eye and xerostomia (dry mouth). [9] All antipsychotics can cause the rare and sometimes fatal neuroleptic malignant syndrome. [10] Trifluoperazine can lower the seizure threshold. [11] The antimuscarinic action of trifluoperazine can cause excessive dilation of the pupils (mydriasis), which increases the chances of patients with hyperopia developing glaucoma. [12]
Trifluoperazine is contraindicated in CNS depression, coma, and blood dyscrasias. Trifluoperazine should be used with caution in patients suffering from renal or hepatic impairment.
Trifluoperazine has central antiadrenergic, [13] antidopaminergic, [14] [15] and minimal anticholinergic effects. [16] It is believed to work by blockading dopamine D1 and D2 receptors in the mesocortical and mesolimbic pathways, relieving or minimizing such symptoms of schizophrenia as hallucinations, delusions, and disorganized thought and speech. [9] It also has antihistaminergic properties (H1 Ki = 17.5 [17] ).
Brand names include Eskazinyl, Eskazine, Jatroneural, Modalina, Sizonil, Stelazine, Stilizan, Terfluzine, Trifluoperaz and Triftazin.
In the United Kingdom and some other countries, trifluoperazine is sold and marketed under the brand 'Stelazine'.
The drug is sold as tablet, liquid and 'Trifluoperazine-injectable USP' for deep intramuscular short-term use.
In the past, trifluoperazine was used in fixed combinations with the MAO inhibitor (antidepressant) tranylcypromine (tranylcypromine/trifluoperazine) to attenuate the strong stimulating effects of this antidepressant. This combination was sold under the brand name Jatrosom N, Stelapar, Parstelin, among others. It remained available in Italy under the brand name Parmodalin (10 mg of tranylcypromine and 1 mg of trifluoperazine) until its discontinuation in 2019.
Likewise, a combination with amobarbital (potent sedative/hypnotic agent) for the amelioration of psychoneurosis and insomnia existed under the brand name Jalonac.
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.
Chlorpromazine (CPZ), marketed under the brand names Thorazine and Largactil among others, is an antipsychotic medication. It is primarily used to treat psychotic disorders such as schizophrenia. Other uses include the treatment of bipolar disorder, severe behavioral problems in children including those with attention deficit hyperactivity disorder, nausea and vomiting, anxiety before surgery, and hiccups that do not improve following other measures. It can be given orally, by intramuscular injection, or intravenously.
Fluphenazine, sold under the brand name Prolixin among others, is a high-potency typical antipsychotic medication. It is used in the treatment of chronic psychoses such as schizophrenia, and appears to be about equal in effectiveness to low-potency antipsychotics like chlorpromazine. It is given by mouth, injection into a muscle, or just under the skin. There is also a long acting injectable version that may last for up to four weeks. Fluphenazine decanoate, the depot injection form of fluphenazine, should not be used by people with severe depression.
Typical antipsychotics are a class of antipsychotic drugs first developed in the 1950s and used to treat psychosis. Typical antipsychotics may also be used for the treatment of acute mania, agitation, and other conditions. The first typical antipsychotics to come into medical use were the phenothiazines, namely chlorpromazine which was discovered serendipitously. Another prominent grouping of antipsychotics are the butyrophenones, an example of which is haloperidol. The newer, second-generation antipsychotics, also known as atypical antipsychotics, have largely supplanted the use of typical antipsychotics as first-line agents due to the higher risk of movement disorders with typical antipsychotics.
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.
Risperidone, sold under the brand name Risperdal among others, is an atypical antipsychotic used to treat schizophrenia and bipolar disorder. It is taken either by mouth or by injection. The injectable versions are long-acting and last for 2–4 weeks.
Quetiapine, sold under the brand name Seroquel among others, is an atypical antipsychotic medication used for the treatment of schizophrenia, bipolar disorder, and major depressive disorder. Despite being widely used as a sleep aid due to its sedating effect, the benefits of such use may not outweigh its undesirable side effects. It is taken orally.
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.
Tardive dyskinesia (TD) is a disorder that results in involuntary repetitive body movements, which may include grimacing, sticking out the tongue or smacking the lips. Additionally, there may be chorea or athetosis. In about 20% of people with TD, the disorder interferes with daily functioning. If TD is present in the setting of a long-term drug therapy, reversibility can be determined primarily by severity of symptoms and how long symptoms have been present before the long-term drug has been stopped.
Loxapine, sold under the brand names Loxitane and Adasuve among others, is a tricyclic antipsychotic medication used primarily in the treatment of schizophrenia. The medicine is a member of the dibenzoxazepine class and structurally very similar to clozapine. Several researchers have argued that loxapine, initially classified as a typical antipsychotic, behaves as an atypical antipsychotic.
A dopamine antagonist, also known as an anti-dopaminergic and a dopamine receptor antagonist (DRA), is a type of drug which blocks dopamine receptors by receptor antagonism. Most antipsychotics are dopamine antagonists, and as such they have found use in treating schizophrenia, bipolar disorder, and stimulant psychosis. Several other dopamine antagonists are antiemetics used in the treatment of nausea and vomiting.
Prochlorperazine, formerly sold under the brand name Compazine among others, is a medication used to treat nausea, migraines, schizophrenia, psychosis and anxiety. It is a less preferred medication for anxiety. It may be taken by mouth, rectally, injection into a vein, or injection into a muscle.
Levomepromazine, also known as methotrimeprazine, is a phenothiazine neuroleptic drug. Brand names include Nozinan, Levoprome, Detenler, Hirnamin, Levotomin and Neurocil. It is a low-potency antipsychotic with strong analgesic, hypnotic and antiemetic properties that are primarily used in palliative care.
Tiotixene, or thiothixene is a typical antipsychotic agent currently sold under the brand name Navane which is predominantly utilised to treat acute and chronic schizophrenia. Beyond its primary indication, it can exhibit a variety of effects common to neuroleptic drugs including anxiolytic, anti-depressive, and anti-aggressive properties.
Progabide is an analogue and prodrug of γ-aminobutyric acid (GABA) used in the treatment of epilepsy. Via conversion into GABA, progabide behaves as an agonist of the GABAA, GABAB, and GABAA-ρ receptors.
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.
Flupentixol (INN), also known as flupenthixol, marketed under brand names such as Depixol and Fluanxol is a typical antipsychotic drug of the thioxanthene class. It was introduced in 1965 by Lundbeck. In addition to single drug preparations, it is also available as flupentixol/melitracen—a combination product containing both melitracen and flupentixol . Flupentixol is not approved for use in the United States. It is, however, approved for use in the UK, Australia, Canada, Russian Federation, South Africa, New Zealand, Philippines, Iran, Germany, and various other countries.
Clotiapine (Entumine) is an atypical antipsychotic of the dibenzothiazepine chemical class. It was first introduced in a few European countries, Argentina, Taiwan and Israel in 1970.
