🩺 Clinical
Paliperidone is used to treat the symptoms of schizophrenia (a mental illness that affects how a person thinks, feels and behaves) and schizoaffective disorder (a mental illness with symptoms of schizophrenia and a mood disorder such as depression or mania). Paliperidone is in a class of medications called atypical antipsychotics. It works by changing the activity of certain natural substances in the brain.

INVEGA is not approved for the treatment of patients with dementia-related psychosis. [see Warnings and Precautions (5.1) ] WARNING: INCREASED MORTALITY IN ELDERLY PATIENTS WITH DEMENTIA-RELATED PSYCHOSIS See full prescribing information for complete boxed warning . Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death.
INVEGA is not approved for use in patients with dementia-related psychosis. ( 5.1 )
🎯 Indications and Usage ▾
1 INDICATIONS AND USAGE INVEGA is an atypical antipsychotic agent indicated for Treatment of schizophrenia ( 1.1 ) Adults: Efficacy was established in three 6-week trials and one maintenance trial. ( 14.1 ) Adolescents (ages 12–17): Efficacy was established in one 6-week trial. ( 14.1 ) Treatment of schizoaffective disorder as monotherapy and as an adjunct to mood stabilizers and/or antidepressants.
( 1.2 ) Efficacy was established in two 6-week trials in adult patients. ( 14.2 )
1.1Schizophrenia INVEGA (paliperidone) Extended-Release Tablets are indicated for the treatment of schizophrenia [see Clinical Studies (14.1) ] . The efficacy of INVEGA in schizophrenia was established in three 6-week trials in adults and one 6-week trial in adolescents, as well as one maintenance trial in adults.
1.2Schizoaffective Disorder INVEGA (paliperidone) Extended-Release Tablets are indicated for the treatment of schizoaffective disorder as monotherapy and an adjunct to mood stabilizers and/or antidepressant therapy [see Clinical Studies (14.2) ] . The efficacy of INVEGA in schizoaffective disorder was established in two 6-week trials in adults.
⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION Initial Dose Recommended Dose Maximum Dose Schizophrenia - adults ( 2.1 ) 6 mg/day 3 – 12 mg/day 12 mg/day Schizophrenia-adolescents ( 2.1 ) Weight < 51kg 3 mg/day 3 – 6 mg/day 6 mg/day Weight ≥ 51kg 3 mg/day 3 – 12 mg/day 12 mg/day Schizoaffective disorder - adults ( 2.2 ) 6 mg/day 3 – 12 mg/day 12 mg/day Tablet should be swallowed whole and should not be chewed, divided, or crushed. ( 2.3 )
2.1Schizophrenia Adults The recommended dose of INVEGA (paliperidone) Extended-Release Tablets for the treatment of schizophrenia in adults is 6 mg administered once daily. Initial dose titration is not required. Although it has not been systematically established that doses above 6 mg have additional benefit, there was a general trend for greater effects with higher doses.
This must be weighed against the dose-related increase in adverse reactions. Thus, some patients may benefit from higher doses, up to 12 mg/day, and for some patients, a lower dose of 3 mg/day may be sufficient. Dose increases above 6 mg/day should be made only after clinical reassessment and generally should occur at intervals of more than 5 days.
When dose increases are indicated, increments of 3 mg/day are recommended. The maximum recommended dose is 12 mg/day. In a longer-term study, INVEGA has been shown to be effective in delaying time to relapse in patients with schizophrenia who were stabilized on INVEGA for 6 weeks [see Clinical Studies (14) ] .
INVEGA should be prescribed at the lowest effective dose for maintaining clinical stability and the physician should periodically reevaluate the long-term usefulness of the drug in individual patients. Adolescents (12–17 years of age) The recommended starting dose of INVEGA (paliperidone) Extended-Release Tablets for the treatment of schizophrenia in adolescents 12–17 years of age is 3 mg administered once daily. Initial dose titration is not required.
Dose increases, if considered necessary, should be made only after clinical reassessment and should occur at increments of 3 mg/day at intervals of more than 5 days. Prescribers should be mindful that, in the adolescent schizophrenia study, there was no clear enhancement to efficacy at the higher doses, i.e., 6 mg for subjects weighing less than 51 kg and 12 mg for subjects weighing 51 kg or greater, while adverse events were dose-related.
2.2Schizoaffective Disorder The recommended dose of INVEGA (paliperidone) Extended-Release Tablets for the treatment of schizoaffective disorder in adults is 6 mg administered once daily. Initial dose titration is not required. Some patients may benefit from lower or higher doses within the recommended dose range of 3 to 12 mg once daily.
A general trend for greater effects was seen with higher doses. This trend must be weighed against dose-related increase in adverse reactions. Dosage adjustment, if indicated, should occur only after clinical reassessment.
Dose increases, if indicated, generally should occur at intervals of more than 4 days. When dose increases are indicated, increments of 3 mg/day are recommended. The maximum recommended dose is 12 mg/day.
2.3Administration Instructions INVEGA can be taken with or without food. INVEGA must be swallowed whole with the aid of liquids. Tablets should not be chewed, divided, or crushed.
The medication is contained within a nonabsorbable shell designed to release the drug at a controlled rate. The tablet shell, along with insoluble core components, is eliminated from the body; patients should not be concerned if they occasionally notice in their stool something that looks like a tablet.
2.4Use with Risperidone Concomitant use of INVEGA with risperidone has not been studied. Since paliperidone is the major active metabolite of risperidone, consideration should be given to the additive paliperidone exposure if risperidone is coadministered with INVEGA.

⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Cerebrovascular Adverse Reactions: An increased incidence of cerebrovascular adverse reactions (e.g. stroke, transient ischemic attack, including fatalities) has been seen in elderly patients with dementia- related psychoses treated with atypical antipsychotics. ( 5.2 ) Neuroleptic Malignant Syndrome: Manage with immediate discontinuation of drug and close monitoring. ( 5.3 ) QT Prolongation: Increase in QT interval, avoid use with drugs that also increase QT interval and in patients with risk factors for prolonged QT interval.
( 5.4 ) Tardive Dyskinesia: Discontinue drug if clinically appropriate. ( 5.5 ) Metabolic Changes: Atypical antipsychotic drugs have been associated with metabolic changes that may increase cardiovascular/ cerebrovascular risk. These metabolic changes include hyperglycemia, dyslipidemia, and weight gain.
( 5.6 ) Hyperglycemia and Diabetes Mellitus: Monitor patients for symptoms of hyperglycemia including polydipsia, polyuria, polyphagia, and weakness. Monitor glucose regularly in patients with diabetes or at risk for diabetes. ( 5.6 ) Dyslipidemia: Undesirable alterations have been observed in patients treated with atypical antipsychotics.
( 5.6 ) Weight Gain: Significant weight gain has been reported. Monitor weight gain. ( 5.6 ) Hyperprolactinemia: Prolactin elevations occur and persist during chronic administration.
( 5.7 ) Gastrointestinal Narrowing: Obstructive symptoms may result in patients with gastrointestinal disease. ( 5.8 ) Orthostatic Hypotension and Syncope: Use with caution in patients with known cardiovascular or cerebrovascular disease and patients predisposed to hypotension. ( 5.9 ) Leukopenia, Neutropenia, and Agranulocytosis: has been reported with antipsychotics, including INVEGA.
Patients with a history of a clinically significant low white blood cell count (WBC) or a drug-induced leukopenia/neutropenia should have their complete blood count (CBC) monitored frequently during the first few months of therapy and discontinuation of INVEGA should be considered at the first sign of a clinically significant decline in WBC in the absence of other causative factors. ( 5.11 ) Potential for Cognitive and Motor Impairment: Use caution when operating machinery. ( 5.12 ) Seizures: Use cautiously in patients with a history of seizures or with conditions that lower the seizure threshold.
( 5.13 )
5.1Increased Mortality in Elderly Patients with Dementia-Related Psychosis Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. Analyses of 17 placebo-controlled trials (modal duration of 10 weeks), largely in patients taking atypical antipsychotic drugs, revealed a risk of death in drug-treated patients of between 1.6 to 1.7 times the risk of death in placebo-treated patients. Over the course of a typical 10-week controlled trial, the rate of death in drug-treated patients was about 4.5%, compared to a rate of about 2.6% in the placebo group.
Although the causes of death were varied, most of the deaths appeared to be either cardiovascular (e.g., heart failure, sudden death) or infectious (e.g., pneumonia) in nature. Observational studies suggest that, similar to atypical antipsychotic drugs, treatment with conventional antipsychotic drugs may increase mortality. The extent to which the findings of increased mortality in observational studies may be attributed to the antipsychotic drug as opposed to some characteristic(s) of the patients is not clear.
INVEGA (paliperidone) is not approved for the treatment of dementia-related psychosis [see Boxed Warning ] .
5.2Cerebrovascular Adverse Reactions, Including Stroke, in Elderly Patients with Dementia-Related Psychosis In placebo-controlled trials with risperidone, aripiprazole, and olanzapine in elderly subjects with dementia, there was a higher incidence of cerebrovascular adverse reactions (cerebrovascular accidents and transient ischemic attacks) including fatalit…

6.1Clinical Trials Experience The most common adverse reactions in clinical trials in adult subjects with schizophrenia (reported in 5% or more of subjects treated with INVEGA and at least twice the placebo rate in any of the dose groups) were extrapyramidal symptoms, tachycardia, and akathisia. The most common adverse reactions in clinical trials in adult patients with schizoaffective disorder (reported in 5% or more of subjects treated with INVEGA and at least twice the placebo rate) were extrapyramidal symptoms, somnolence, dyspepsia, constipation, weight increased, and nasopharyngitis.
The most common adverse reactions that were associated with discontinuation from clinical trials in adult subjects with schizophrenia (causing discontinuation in 2% of INVEGA-treated subjects) were nervous system disorders. The most common adverse reactions that were associated with discontinuation from clinical trials in adult subjects with schizoaffective disorder were gastrointestinal disorders, which resulted in discontinuation in 1% of INVEGA-treated subjects. [See Adverse Reactions (6) ] . The safety of INVEGA was evaluated in 1205 adult subjects with schizophrenia who participated in three placebo-controlled, 6-week, double-blind trials, of whom 850 subjects received INVEGA at fixed doses ranging from 3 mg to 12 mg once daily.
The information presented in this section was derived from pooled data from these three trials. Additional safety information from the placebo-controlled phase of the long-term maintenance study, in which subjects received INVEGA at daily doses within the range of 3 mg to 15 mg (n=104), is also included. The safety of INVEGA was evaluated in 150 adolescent subjects 12–17 years of age with schizophrenia who received INVEGA in the dose range of 1.5 mg to 12 mg/day in a 6-week, double-blind, placebo-controlled trial.
The safety of INVEGA was also evaluated in 622 adult subjects with schizoaffective disorder who participated in two placebo-controlled, 6-week, double-blind trials. In one of these trials, 206 subjects were assigned to one of two dose levels of INVEGA: 6 mg with th…
🔄 Drug Interactions ▾
7 DRUG INTERACTIONS Centrally-acting drugs: Due to CNS effects, use caution in combination. Avoid alcohol. ( 7.1 ) Drugs that may cause orthostatic hypotension: An additive effect may be observed when co-administered with INVEGA.
( 7.1 ) Strong CYP3A4/P-glycoprotein (P-gp) inducers: It may be necessary to increase the dose of INVEGA when a strong inducer of both CYP3A4 and P-gp (e.g., carbamazepine) is co-administered. Conversely, on discontinuation of the strong inducer, it may be necessary to decrease the dose of INVEGA. ( 7.2 ) Co-administration of divalproex sodium increased C max and AUC of paliperidone by approximately 50%.
Adjust dose of INVEGA if necessary based on clinical assessment. ( 7.2 )
7.1Potential for INVEGA to Affect Other Drugs Given the primary CNS effects of paliperidone [see Adverse Reactions (6.1 , 6.2 )] , INVEGA should be used with caution in combination with other centrally acting drugs and alcohol. Paliperidone may antagonize the effect of levodopa and other dopamine agonists. Because of its potential for inducing orthostatic hypotension, an additive effect may be observed when INVEGA is administered with other therapeutic agents that have this potential [see Warnings and Precautions (5.9) ] .
Paliperidone is not expected to cause clinically important pharmacokinetic interactions with drugs that are metabolized by cytochrome P450 isozymes. In vitro studies in human liver microsomes showed that paliperidone does not substantially inhibit the metabolism of drugs metabolized by cytochrome P450 isozymes, including CYP1A2, CYP2A6, CYP2C8/9/10, CYP2D6, CYP2E1, CYP3A4, and CYP3A5. Therefore, paliperidone is not expected to inhibit clearance of drugs that are metabolized by these metabolic pathways in a clinically relevant manner.
Paliperidone is also not expected to have enzyme inducing properties. Paliperidone is a weak inhibitor of P-glycoprotein (P-gp) at high concentrations. No in vivo data are available and the clinical relevance is unknown.
Pharmacokinetic interaction between lithium and INVEGA is unlikely. In a drug interaction study, co-administration of INVEGA (12 mg once daily for 5 days) with divalproex sodium extended-release tablets (500 mg to 2000 mg once daily) did not affect the steady-state pharmacokinetics (AUC 24h and C max,ss ) of valproate in 13 patients stabilized on valproate. In a clinical study, subjects on stable doses of valproate had comparable valproate average plasma concentrations when INVEGA 3–15 mg/day was added to their existing valproate treatment.
7.2Potential for Other Drugs to Affect INVEGA Paliperidone is not a substrate of CYP1A2, CYP2A6, CYP2C9, and CYP2C19, so that an interaction with inhibitors or inducers of these isozymes is unlikely. While in vitro studies indicate that CYP2D6 and CYP3A4 may be minimally involved in paliperidone metabolism, in vivo studies do not show decreased elimination by these isozymes and they contribute to only a small fraction of total body clearance. In vitro studies have shown that paliperidone is a P-gp substrate.
Co-administration of INVEGA 6 mg once daily with carbamazepine, a strong inducer of both CYP3A4 and P-glycoprotein (P-gp), at 200 mg twice daily caused a decrease of approximately 37% in the mean steady-state C max and AUC of paliperidone. This decrease is caused, to a substantial degree, by a 35% increase in renal clearance of paliperidone. A minor decrease in the amount of drug excreted unchanged in the urine suggests that there was little effect on the CYP metabolism or bioavailability of paliperidone during carbamazepine co-administration.
On initiation of carbamazepine, the dose of INVEGA should be re-evaluated and increased if necessary. Conversely, on discontinuation of carbamazepine, the dose of INVEGA should be re-evaluated and decreased if necessary. Paliperidone is metabolized to a limited extent by CYP2D6 [see Clinical Pharmacology (12.3) ] .

👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Renal impairment: Dosing must be individualized according to renal function status. ( 2.5 ) Elderly: Same as for younger adults (adjust dose according to renal function status). ( 2.5 ) Pregnancy: May cause extrapyramidal and/or withdrawal symptoms in neonates with third trimester exposure.
( 8.1 ) Pediatric Use: Safety and effectiveness in the treatment of schizophrenia not established in patients less than 12 years of age. Safety and effectiveness in the treatment of schizoaffective disorder not established in patients less than 18 years of age. ( 8.4 )
8.1Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to atypical antipsychotics, including INVEGA, during pregnancy. Healthcare providers are encouraged to register patients by contacting the National Pregnancy Registry for Atypical Antipsychotics at 1-866-961-2388 or online at http://womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/. Risk Summary Neonates exposed to antipsychotic drugs during the third trimester of pregnancy are at risk for extrapyramidal and/or withdrawal symptoms following delivery (see Clinical Considerations ) .
Overall, available data from published epidemiologic studies of pregnant women exposed to paliperidone have not established a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes (see Data ) . There are risks to the mother associated with untreated schizophrenia and with exposure to antipsychotics, including INVEGA, during pregnancy (see Clinical Considerations ). The estimated background risk of major birth defects and miscarriage for the indicated population is unknown.
All pregnancies have a background risk of birth defects, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2–4% and 15–20%, respectively. In animal reproduction studies, there were no increases in fetal abnormalities when pregnant rats and rabbits were treated with paliperidone during the period of organogenesis with up to 8 times the maximum recommended human dose (MRHD) based on mg/m 2 body surface area.
Additional reproduction toxicity studies were conducted with orally administered risperidone, which is extensively converted to paliperidone (see Animal data ). Clinical Considerations Disease-associated maternal and/or embryo/fetal risk There is a risk to the mother from untreated schizophrenia, including increased risk of relapse, hospitalization, and suicide. Schizophrenia are associated with increased adverse perinatal outcomes, including preterm birth.
It is not known if this is a direct result of the illness or other comorbid factors. Fetal/Neonatal Adverse Reactions Extrapyramidal and/or withdrawal symptoms, including agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress, and feeding disorder have been reported in neonates who were exposed to antipsychotic drugs, including INVEGA, during the third trimester of pregnancy. These symptoms have varied in severity.

8.1Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to atypical antipsychotics, including INVEGA, during pregnancy. Healthcare providers are encouraged to register patients by contacting the National Pregnancy Registry for Atypical Antipsychotics at 1-866-961-2388 or online at http://womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/. Risk Summary Neonates exposed to antipsychotic drugs during the third trimester of pregnancy are at risk for extrapyramidal and/or withdrawal symptoms following delivery (see Clinical Considerations ) .
Overall, available data from published epidemiologic studies of pregnant women exposed to paliperidone have not established a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes (see Data ) . There are risks to the mother associated with untreated schizophrenia and with exposure to antipsychotics, including INVEGA, during pregnancy (see Clinical Considerations ). The estimated background risk of major birth defects and miscarriage for the indicated population is unknown.
All pregnancies have a background risk of birth defects, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2–4% and 15–20%, respectively. In animal reproduction studies, there were no increases in fetal abnormalities when pregnant rats and rabbits were treated with paliperidone during the period of organogenesis with up to 8 times the maximum recommended human dose (MRHD) based on mg/m 2 body surface area.
Additional reproduction toxicity studies were conducted with orally administered risperidone, which is extensively converted to paliperidone (see Animal data ). Clinical Considerations Disease-associated maternal and/or embryo/fetal risk There is a risk to the mother from untreated schizophrenia, including increased risk of relapse, hospitalization, and suicide. Schizophrenia are associated with increased adverse perinatal outcomes, including preterm birth.
It is not known if this is a direct result of the illness or other comorbid factors. Fetal/Neonatal Adverse Reactions Extrapyramidal and/or withdrawal symptoms, including agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress, and feeding disorder have been reported in neonates who were exposed to antipsychotic drugs, including INVEGA, during the third trimester of pregnancy. These symptoms have varied in severity.
Monitor neonates for extrapyramidal and/or withdrawal symptoms and manage symptoms appropriately. Some neonates recovered within hours or days without specific treatment; others required prolonged hospitalization. Data Human Data Published data from observational studies, birth registries, and case reports on the use of atypical antipsychotics during pregnancy do not report a clear association with antipsychotics and major birth defects.
A prospective observational study including 6 women treated with risperidone, the parent compound of paliperidone, demonstrated placental passage of risperidone and paliperidone. A retrospective cohort study from a Medicaid database of 9258 women exposed to antipsychotics during pregnancy did not indicate an overall increased risk for major birth defects. There was a small increase in the risk of major birth defects (RR= 1.26, 95% CI 1.02–1.56) and of cardiac malformations (RR=1.26, 95% CI 0.88–1.81) in a subgroup of 1566 women exposed to the parent compound of paliperidone, risperidone, during the first trimester of pregnancy; however, there is no mechanism of action to explain the difference in malformation rates.
Animal Data In animal reproduction studies, there were no increases in fetal abnormalities when pregnant rats and rabbits were treated with paliperidone during the period of organogenesis with up to 8 times the MRHD of 12 mg based on mg…
🧒 Pediatric Use ▾
8.4Pediatric Use Safety and effectiveness of INVEGA in the treatment of schizophrenia were evaluated in 150 adolescent subjects 12–17 years of age with schizophrenia who received INVEGA in the dose range of 1.5 mg to 12 mg/day in a 6-week, double-blind, placebo-controlled trial. Safety and effectiveness of INVEGA for the treatment of schizophrenia in patients < 12 years of age have not been established. Safety and effectiveness of INVEGA for the treatment of schizoaffective disorder in patients < 18 years of age have not been studied.
Juvenile Animal Studies In a study in which juvenile rats were treated with oral paliperidone from days 24 to 73 of age, a reversible impairment of performance in a test of learning and memory was seen, in females only, with a no-effect dose of 0.63 mg/kg/day, which produced plasma levels (AUC) of paliperidone similar to those in adolescents at MRHD of 12 mg/day. No other consistent effects on neurobehavioral or reproductive development were seen up to the highest dose tested (2.5 mg/kg/day), which produced plasma levels of paliperidone 2–3 times those in adolescents.
Juvenile dogs were treated for 40 weeks with oral risperidone, which is extensively metabolized to paliperidone in animals and humans, at doses of 0.31, 1.25, or 5 mg/kg/day. Decreased bone length and density were seen with a no-effect dose of 0.31 mg/kg/day, which produced plasma levels (AUC) of risperidone plus paliperidone which were similar to those in children and adolescents receiving the MRHD of risperidone. In addition, a delay in sexual maturation was seen at all doses in both males and females.
The above effects showed little or no reversibility in females after a 12-week drug-free recovery period. The long-term effects of INVEGA on growth and sexual maturation have not been fully evaluated in children and adolescents.
🧓 Geriatric Use ▾
8.5Geriatric Use The safety, tolerability, and efficacy of INVEGA were evaluated in a 6-week placebo-controlled study of 114 elderly subjects with schizophrenia (65 years of age and older, of whom 21 were 75 years of age and older). In this study, subjects received flexible doses of INVEGA (3 mg to 12 mg once daily). In addition, a small number of subjects 65 years of age and older were included in the 6-week placebo-controlled studies in which adult schizophrenic subjects received fixed doses of INVEGA (3 mg to 15 mg once daily) [see Clinical Studies (14) ] .
There were no subjects ≥ 65 years of age in the schizoaffective disorder studies. Overall, of the total number of subjects in schizophrenia clinical studies of INVEGA (n=1796), including those who received INVEGA or placebo, 125 (7.0%) were 65 years of age and older and 22 (1.2%) were 75 years of age and older. No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in response between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out.
This drug is known to be substantially excreted by the kidney and clearance is decreased in patients with moderate to severe renal impairment [see Clinical Pharmacology (12.3) ] , who should be given reduced doses. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function [see Dosage and Administration (2.5) ] .
🆘 Overdosage ▾
10 OVERDOSAGE
10.1Human Experience While experience with paliperidone overdose is limited, among the few cases of overdose reported in pre-marketing trials, the highest estimated ingestion of INVEGA was 405 mg. Observed signs and symptoms included extrapyramidal symptoms and gait unsteadiness. Other potential signs and symptoms include those resulting from an exaggeration of paliperidone's known pharmacological effects, i.e., drowsiness and somnolence, tachycardia and hypotension, and QT prolongation.
Torsade de pointes and ventricular fibrillation have been reported in a patient in the setting of overdose. Paliperidone is the major active metabolite of risperidone. Overdose experience reported with risperidone can be found in the OVERDOSAGE section of the risperidone package insert.
10.2Management of Overdosage There is no specific antidote to paliperidone, therefore, appropriate supportive measures should be instituted and close medical supervision and monitoring should continue until the patient recovers. Consideration should be given to the extended-release nature of the product when assessing treatment needs and recovery. Multiple drug involvement should also be considered.
In case of acute overdose, establish and maintain an airway and ensure adequate oxygenation and ventilation. Administration of activated charcoal together with a laxative should be considered. The possibility of obtundation, seizures, or dystonic reaction of the head and neck following overdose may create a risk of aspiration with induced emesis.
Cardiovascular monitoring should commence immediately, including continuous electrocardiographic monitoring for possible arrhythmias. If antiarrhythmic therapy is administered, disopyramide, procainamide, and quinidine carry a theoretical hazard of additive QT-prolonging effects when administered in patients with an acute overdose of paliperidone. Similarly, the alpha-blocking properties of bretylium might be additive to those of paliperidone, resulting in problematic hypotension.
Hypotension and circulatory collapse should be treated with appropriate measures, such as intravenous fluids and/or sympathomimetic agents (epinephrine and dopamine should not be used, since beta stimulation may worsen hypotension in the setting of paliperidone-induced alpha blockade). In cases of severe extrapyramidal symptoms, anticholinergic medication should be administered.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Paliperidone is the major active metabolite of risperidone. The mechanism of action of paliperidone in schizophrenia is unclear. However, the drug's therapeutic effect in schizophrenia could be mediated through a combination of central dopamine Type 2 (D 2 ) and serotonin Type 2 (5HT 2A ) receptor antagonism.
12.2Pharmacodynamics In vitro , paliperidone acts as an antagonist at the central dopamine Type 2 (D 2 ) and serotonin Type 2 (5HT 2A ) receptors, with binding affinities (Ki values) of 1.6–2.8 nM for D 2 and 0.8–1.2 nM for 5HT 2A receptors. Paliperidone is also active as an antagonist at the α 1 and α 2 adrenergic receptors and H 1 histaminergic receptors, which may explain some of the other effects of the drug. Paliperidone has no affinity for cholinergic muscarinic or β 1 - and β 2 -adrenergic receptors.
The pharmacological activity of the (+)- and (-)- paliperidone enantiomers is qualitatively and quantitatively similar in vitro.
12.3Pharmacokinetics Following a single dose, the plasma concentrations of paliperidone gradually rise to reach peak plasma concentration (C max ) approximately 24 hours after dosing. The pharmacokinetics of paliperidone following INVEGA administration are dose-proportional within the available dose range. The terminal elimination half-life of paliperidone is approximately 23 hours.
Steady-state concentrations of paliperidone are attained within 4–5 days of dosing with INVEGA in most subjects. The mean steady-state peak:trough ratio for an INVEGA dose of 9 mg was 1.7 with a range of 1.2–3.1. Following administration of INVEGA, the (+) and (-) enantiomers of paliperidone interconvert, reaching an AUC (+) to (-) ratio of approximately 1.6 at steady state.
Absorption and Distribution The absolute oral bioavailability of paliperidone following INVEGA administration is 28%. Administration of a 12 mg paliperidone extended-release tablet to healthy ambulatory subjects with a standard high-fat/high-caloric meal gave mean C max and AUC values of paliperidone that were increased by 60% and 54%, respectively, compared with administration under fasting conditions. Clinical trials establishing the safety and efficacy of INVEGA were carried out in subjects without regard to the timing of meals.
While INVEGA can be taken without regard to food, the presence of food at the time of INVEGA administration may increase exposure to paliperidone [see Dosage and Administration (2.3) ] . Based on a population analysis, the apparent volume of distribution of paliperidone is 487 L. The plasma protein binding of racemic paliperidone is 74%.
Metabolism and Elimination Although in vitro studies suggested a role for CYP2D6 and CYP3A4 in the metabolism of paliperidone, in vivo results indicate that these isozymes play a limited role in the overall elimination of paliperidone [see Drug Interactions (7) ] . One week following administration of a single oral dose of 1 mg immediate-release 14 C-paliperidone to 5 healthy volunteers, 59% (range 51% – 67%) of the dose was excreted unchanged into urine, 32% (26% – 41%) of the dose was recovered as metabolites, and 6% – 12% of the dose was not recovered.
Approximately 80% of the administered radioactivity was recovered in urine and 11% in the feces. Four primary metabolic pathways have been identified in vivo , none of which could be shown to account for more than 10% of the dose: dealkylation, hydroxylation, dehydrogenation, and benzisoxazole scission. Population pharmacokinetic analyses found no difference in exposure or clearance of paliperidone between extensive metabolizers and poor metabolizers of CYP2D6 substrates.
Special Populations Renal Impairment The dose of INVEGA should be reduced in patients with moderate or severe renal impairment [see Dosage and Administration (2.5) ] . The disposition of a single dose paliperidone 3 mg extended-release tablet was studied in adult subjects with varying degrees of renal function. E…

📋 Description ▾
11 DESCRIPTION INVEGA ® contains paliperidone, an atypical antipsychotic belonging to the chemical class of benzisoxazole derivatives. INVEGA contains a racemic mixture of (+)- and (-)- paliperidone. The chemical name is (±)-3-[2-[4-(6-fluoro-1,2-benzisoxazol-3-yl)-1-piperidinyl]ethyl]-6,7,8,9-tetrahydro-9-hydroxy-2-methyl-4H-pyrido[1,2-a]pyrimidin-4-one.
Its molecular formula is C 23 H 27 FN 4 O 3 and its molecular weight is 426.49. The structural formula is: Paliperidone is sparingly soluble in 0.1N HCl and methylene chloride; practically insoluble in water, 0.1N NaOH, and hexane; and slightly soluble in N,N-dimethylformamide. INVEGA (paliperidone) Extended-Release Tablets are intended for oral administration and are available in 3 mg (white), 6 mg (beige), and 9 mg (pink) strengths.
INVEGA utilizes OROS ® osmotic drug-release technology. Inactive ingredients are carnauba wax, cellulose acetate, hydroxyethyl cellulose, propylene glycol, polyethylene glycol, polyethylene oxides, povidone, sodium chloride, stearic acid, butylated hydroxytoluene, hypromellose, titanium dioxide, and iron oxides. The 3 mg tablets also contain lactose monohydrate and triacetin.
Chemical Structure Delivery System Components and Performance INVEGA uses osmotic pressure to deliver paliperidone at a controlled rate. The delivery system, which resembles a capsule-shaped tablet in appearance, consists of an osmotically active trilayer core surrounded by a subcoat and semipermeable membrane. The trilayer core is composed of two drug layers containing the drug and excipients, and a push layer containing osmotically active components.
There are two precision laser-drilled orifices on the drug-layer dome of the tablet. Each tablet strength has a different colored water-dispersible overcoat and print markings. In an aqueous environment, such as the gastrointestinal tract, the water-dispersible color overcoat erodes quickly.
Water then enters the tablet through the semipermeable membrane that controls the rate at which water enters the tablet core, which, in turn, determines the rate of drug delivery. The hydrophilic polymers of the core hydrate and swell, creating a gel containing paliperidone that is then pushed out through the tablet orifices. The biologically inert components of the tablet remain intact during gastrointestinal transit and are eliminated in the stool as a tablet shell, along with insoluble core components.
