Paliperidone, sold under the brand name Invega among others, is an atypical antipsychotic. [12] It is mainly used to treat schizophrenia and schizoaffective disorder. [12] It is marketed by Janssen Pharmaceuticals. [3]
Paliperidone was approved by the US Food and Drug Administration (FDA) for the treatment of schizophrenia in December 2006. [3] Paliperidone palmitate is a long-acting injectable formulation of paliperidone palmitoyl ester. [12] [13] It is on the World Health Organization's List of Essential Medicines. [14]
Paliperidone is used for the treatment of schizophrenia and schizoaffective disorder. [15]

The British National Formulary recommends a gradual withdrawal when discontinuing antipsychotics to avoid acute withdrawal syndrome or rapid relapse. [21] Symptoms of withdrawal commonly include nausea, vomiting, and loss of appetite. [22] Other symptoms may include restlessness, increased sweating, and trouble sleeping. [22] Less commonly there may be a feeling of the world spinning, numbness, or muscle pains. [22] Symptoms generally resolve after a short period of time. [22]
There is tentative evidence that discontinuation of antipsychotics can result in psychosis. [23] It may also result in reoccurrence of the condition that is being treated. [24] Rarely tardive dyskinesia can occur when the medication is stopped. [22]
In April 2014, it was reported that 21 Japanese people who had received shots of the long-acting injectable paliperidone palmitate to date had died, out of 10,700 individuals prescribed the drug. [25] [26] [27] [28] [29] [30] [31]

Paliperidone is the primary active metabolite of the older antipsychotic risperidone. [34] [ unreliable medical source? ] While its specific mechanism of action is unknown, it is believed paliperidone and risperidone act via similar, if not identical, pathways. [32] Its efficacy is believed to result from central dopaminergic and serotonergic antagonism. Paliperidone is also active by acting as an antagonist of the alpha 1 and alpha 2 adrenergic receptors as well as the H1 histaminergic receptors. [34] Food is known to increase the absorption of Invega type ER OROS prolonged-release tablets. Food increased exposure of paliperidone by up to 50-60%, however, half-life was not significantly affected. The effect was probably due to a delay in the transit of the ER OROS formulation in the upper part of the GI channel, resulting in increased absorption. [35]
The half-life is 23 hours. [35]
Risperidone and its metabolite paliperidone are reduced in efficacy by P-glycoprotein inducers such as St John's wort [36] [37]

Paliperidone (as Invega) was approved by the Food and Drug Administration (FDA) for the treatment of schizophrenia in 2006. Paliperidone was approved by the FDA for the treatment of schizoaffective disorder in 2009. The long-acting injectable form of paliperidone, marketed as Invega Sustenna in the US, [5] and Xeplion in the EU, [11] was approved by the FDA in July 2009.
It was initially approved in the European Union in 2007, for schizophrenia, the extended release form and use for schizoaffective disorder were approved in the EU in 2010, and extension to use in adolescents older than 15 years old was approved in 2014. [48]
In May 2015, a formulation of paliperidone palmitate was approved by the FDA under the brand name Invega Trinza. [49] [6] A similar prolonged release suspension was approved in 2016 by the European Medicines Agency originally under the brand name Paliperidone Janssen, later renamed to Trevicta. [50] On September 1, 2021, a newer formulation of paliperidone palmitate, Invega Hafyera, was approved by the US FDA. [4]
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.
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 in the latter.
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.
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.
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, obsessive compulsive disorder (OCD), and bipolar disorder; other uses include as an add-on treatment in major depressive disorder, 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.
Haloperidol decanoate, sold under the brand name Haldol Decanoate among others, is a typical antipsychotic which is used in the treatment of schizophrenia. It is administered by injection into muscle at a dose of 100 to 200 mg once every 4 weeks or monthly. The dorsogluteal site is recommended. A 3.75-cm (1.5-inch), 21-gauge needle is generally used, but obese individuals may require a 6.5-cm (2.5-inch) needle to ensure that the drug is indeed injected intramuscularly and not subcutaneously. Haloperidol decanoate is provided in the form of 50 or 100 mg/mL oil solution of sesame oil and benzyl alcohol in ampoules or pre-filled syringes. Its elimination half-life after multiple doses is 21 days. The medication is marketed in many countries throughout the world.
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.
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.
Fluspirilene is a diphenylbutylpiperidine typical antipsychotic drug, used for the treatment of schizophrenia. It is administered intramuscularly. It was discovered at Janssen Pharmaceutica in 1963. A 2007 systematic review investigated the efficacy of fluspirilene decanoate for people with schizophrenia:
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.
Zuclopenthixol, also known as zuclopentixol, is a medication used to treat schizophrenia and other psychoses. It is classed, pharmacologically, as a typical antipsychotic. Chemically it is a thioxanthene. It is the cis-isomer of clopenthixol. Clopenthixol was introduced in 1961, while zuclopenthixol was introduced in 1978.
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.
Pipotiazine (Piportil), also known as pipothiazine, is a typical antipsychotic of the phenothiazine class used in the United Kingdom and other countries for the treatment of schizophrenia. Its properties are similar to those of chlorpromazine. A 2004 systematic review investigated its efficacy for people with schizophrenia:
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.
Perphenazine enanthate, sold under the brand name Trilafon Enantat among others, is a typical antipsychotic and a depot antipsychotic ester which is used in the treatment of schizophrenia and has been marketed in Europe. It is formulated in sesame oil and administered by intramuscular injection and acts as a long-lasting prodrug of perphenazine. Perphenazine enanthate is used at a dose of 25 to 200 mg once every 2 weeks by injection, with a time to peak levels of 2 to 3 days and an elimination half-life of 4 to 7 days.
Oxyprothepin decanoate, sold under the brand name Meclopin, is a typical antipsychotic which was used in the treatment of schizophrenia in the Czech Republic but is no longer marketed. It is administered by depot injection into muscle. The medication has an approximate duration of 2 to 3 weeks. The history of oxyprothepin decanoate has been reviewed.
An antipsychotic ester is an ester of an antipsychotic. They are used clinically as prodrugs to increase fat solubility and thereby prolong duration when antipsychotics are used as depot injectables.
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.
