paliperidone palmitate

Invega Sustenna

Pharmacologic class: Benzisoxazole derivative

Therapeutic class: Antipsychotic

Pregnancy risk category C

FDA Box Warning

• Elderly patients with dementia-related psychosis are at increased risk for death. Over course of 10-week controlled trial, death rate in drug-treated patients was about 4.5%, compared to about 2.6% in placebo group. Although causes of death varied, most appeared to be cardiovascular or infectious. Don't give drug to patients with dementia-related psychosis.


Unknown. In schizophrenia, therapeutic activity may be mediated through combination of central serotonin2-and dopamine2-receptor antagonism. Drug is a major active metabolite of risperidone.


Injection (paliperidone palmitate): 39 mg, 78 mg, 117 mg, 156 mg, 234 mg in prefilled syringes

Tablets (extended-release): 1.5 mg, 3 mg, 6 mg, 9 mg

Indications and dosages


Adults: 6 mg P.O. once daily. Some patients may benefit from daily dosages as high as 12 mg or as low as 3 mg. If indicated, increase in increments of 3 mg/day at intervals of more than 5 days. Or initially, 234 mg I.M. (paliperidone palmitate) on treatment day 1 and 156 mg I.M. 1 week later. Recommended monthly maintenance dose is 117 mg; some patients may benefit from lower or higher maintenance doses within recommended range of 39 to 234 mg. Adjustment of maintenance dosage may be made monthly. When making dosage adjustments, consider paliperidone palmitate's prolonged-release characteristics, as the full effect of the dosage adjustment may not be evident for several months.

Adolescents ages 12 to 17 weighing 51 kg (112 lb) or more: 3 mg P.O. daily; increase dosage, if necessary, only after clinical reassessment at increments of 3 mg/day at intervals of more than 5 days up to a maximum of 12 mg/day.

Adolescents ages 12 to 17 weighing less than 51 kg (112 lb): 3 mg P.O. daily; increase dosage, if necessary, only after clinical reassessment at increments of 3 mg/day at intervals of more than 5 days up to a maximum of 6 mg/day.

Schizoaffective disorder

Adults: 6 mg P.O. once daily. Some patients may benefit from dosages as high as 12 mg or as low as 3 mg. Maximum recommended dosage is 12 mg/day.

Dosage adjustment

• Renal impairment


• Hypersensitivity to drug, its components, or risperidone


Use cautiously in:

• GI strictures (use should be avoided), cardiovascular or cerebrovascular disease, diabetes mellitus, Parkinson's disease, or conditions that raise body temperature (such as exercise, exposure to extreme heat, and concomitant anticholinergics use)

• increased risk of hypotension (as from dehydration, hypovolemia, or antihypertensives), aspiration pneumonia, or suicide attempt

• increased risk of metabolic changes (including hyperglycemia, dyslipidemia, weight gain)

• concurrent use of other drugs that are centrally acting or prolong the QT interval (use should be avoided)

• history of seizures or breast cancer

• elderly patients with dementia-related psychosis

• pregnant or breastfeeding patients

• children younger than age 18 (safety and efficacy not established).


• Give tablets in morning with or without food.

• Administer tablets whole. Ensure that patient doesn't chew, divide, or crush them.

Administer paliperidone palmitate by deep I.M. injection only as a single injection. Don't give in divided injections. Don't administer I.V. or subcutaneously.

For first and second I.M. doses, give in the deltoid muscle using 1½-inch 22G needle for patients 90 kg (198 lb) or more or 1-inch 23G needle for patients less than 90 kg. After the second dose, monthly maintenance doses may be given in either the deltoid or gluteal muscle. For gluteal injection, use 1½-inch 22G needle regardless of patient weight.

Nursing implications

Nursing assessment

  • Monitor patient’s mental status (orientation, mood, behavior) before and periodically during therapy. Monitor closely for notable changes in behavior that could indicate the emergence or worsening of suicidal thoughts or behavior or depression, especially during early therapy. Restrict amount of drug available to patient.
  • Assess weight and BMI initially and throughout therapy.
  • Monitor BP (sitting, standing, lying down) and pulse before and periodically during therapy. May cause prolonged QT interval, tachycardia, and orthostatic hypotension.
  • Observe patient when administering medication to ensure that medication is actually swallowed and not hoarded or cheeked.
  • Monitor patient for onset of extrapyramidal side effects (akathisia—restlessness; dystonia—muscle spasms and twisting motions; or pseudoparkinsonism—mask-like face, rigidity, tremors, drooling, shuffling gait, dysphagia). Report these symptoms; reduction of dose or discontinuation of medication may be necessary.
  • Monitor for tardive dyskinesia (involuntary rhythmic movement of mouth, face, and extremities). Report immediately; may be irreversible.
  • Monitor for development of neuroleptic malignant syndrome (fever, respiratory distress, tachycardia, seizures, diaphoresis, hypertension or hypotension, pallor, tiredness). Discontinue paliperidone and notify health care professional immediately if these symptoms occur.
  • Monitor for symptoms related to hyperprolactinemia (menstrual abnormalities, galactorrhea, sexual dysfunction).
  • Lab Test Considerations: Monitor fasting blood glucose and cholesterol levels before and periodically during therapy.
    • Monitor serum prolactin prior to and periodically during therapy. May cause ↑ serum prolactin levels.
    • Monitor CBC frequently during initial months of therapy in patients with pre-existing or history of low WBC. May cause leukopenia, neutropenia, or agranulocytosis. Discontinue therapy if this occurs.

Potential Nursing Diagnoses

Risk for self-directed violence (Indications,  Adverse Reactions)
Disturbed sensory perception (specify: visual, auditory, kinesthetic, gustatory, tactile, olfactory) (Indications)


  • Oral: Administer once daily in the morning without regard to food. Tablets should be swallowed whole; do not crush, break or chew.
  • Intramuscular: Administer initial and second doses in deltoid using a 1 1/2-inch, 22 gauge needle for patients ≥90 kg (≥200 lb) or 1-inch 23 gauge needle for patients <90 kg (<200 lb). Monthly maintenance doses can be administered in either deltoid or gluteal sites. For gluteal injection, use 1 1/2-inch, 22 gauge needle regardless of patient weight. To avoid missed dose, may give second dose 4 days before or after the 1-wk timepoint. Monthly doses may be given up to 7 days before or after the monthly timepoint. After 1st month, if missed dose is within 4 wk of scheduled dose, administer 2nd dose of 156 mg as soon as possible. Give 3rd dose of 117 mg in either deltoid or gluteal muscle 5 wk after first injection (regardless of timing of 2nd injection). Then return to normal monthly injections in either deltoid or gluteal muscle. If >4 wk and <7 wk since 1st injection, resume by administering 156 mg dose in deltoid as soon as possible, a second 156 mg dose in deltoid in 1 wk, followed by monthly doses in deltoid or gluteal sites. If > 7 months since scheduled dose, administer using initial dosing schedule. During regular monthly dose schedule, if <6 wks since last injection, administer previously stabilized dose as soon as possible, then monthly. If >6 wks since last injection, resume dose previously stabilized on, unless stabilized on 234 mg (then 1st two injections should be 156 mg). Administer 1 dose in deltoid as soon as possible, then another deltoid injection of same dose 1 wk later, then resume regular monthly schedule. If >6 months since last injection, administer using initial dosing schedule.

Patient/Family Teaching

  • Instruct patient to take medication as directed. Advise patient that appearance of tablets in stool is normal and not of concern.
  • Inform patient of the possibility of extrapyramidal symptoms. Instruct patient to report these symptoms immediately to health care professional.
  • Advise patient to change positions slowly to minimize orthostatic hypotension.
  • May cause drowsiness. Caution patient to avoid driving or other activities requiring alertness until response to medication is known.
  • Advise patient and family to notify health care professional if thoughts about suicide or dying, attempts to commit suicide; new or worse depression; new or worse anxiety; feeling very agitated or restless; panic attacks; trouble sleeping; new or worse irritability; acting aggressive; being angry or violent; acting on dangerous impulses; an extreme increase in activity and talking, other unusual changes in behavior or mood occur.
  • Advise patient that extremes in temperature should also be avoided; this drug impairs body temperature regulation.
  • Advise patient to notify health care professional of all Rx or OTC medications, vitamins, or herbal products being taken and to consult with health care professional before taking other medications and alcohol.
  • Advise patient to seek nutritional, weight, or medical management as needed for weight gain or cholesterol elevation.
  • Instruct patient to notify health care professional promptly if sore throat, fever, unusual bleeding or bruising, rash, tremors, menstrual abnormalities, galactorrhea, or sexual dysfunction occur.
  • Advise patient to notify health care professional of medication regimen before treatment or surgery.
  • Advise female patients to notify health care professional if pregnancy is planned or suspected, or if breast feeding or planning to breast feed.
  • Emphasize the importance of routine follow-up exams to monitor side effects and continued participation in psychotherapy to improve coping skills.

Evaluation/Desired Outcomes

  • Decrease in excited, manic behavior.
  • Decrease in positive symptoms (delusions, hallucinations) of schizophrenia.
  • Decrease in negative symptoms (social withdrawal, flat, blunted affect) of schizophrenia.

Alkermes announced positive topline results from ALPINE, a first-of-its-kind, six-month study evaluating the efficacy, safety and tolerability of ARISTADA and INVEGA SUSTENNA when used to initiate patients experiencing an acute exacerbation of schizophrenia in the hospital and maintain treatment in an outpatient setting.
Specifically, all-cause mortality was reduced by 89% while patients were on once-monthly palpiperidone palmitate LAI (Invega Sustenna) than during periods when they were not using an antipsychotic.
Pharmaceuticals, Invega Sustenna (Paliperidone Palmitate) Extended Release Injectable Suspension: Prescribing Information, Orth-McNeil-Janssen Pharmaceuticals, Inc, 2009.
Such products include parenteral sustained-release depots such as Risperdal Consta (risperidone), Zyprexa Relprevv (olanzapine pamoate), Vivitrol (naltrexone) and Invega Sustenna (paliperidone palmitate).
Johnson and Johnson Pharmaceutical R&D submitted the NDA for the drug paliperidone palmitate, now known as Invega Sustenna, for the acute and maintenance treatment of schizophrenia.
Before starting treatment with Invega Trinza, patients must first be treated with Invega Sustenna (paliperidone palmitate) for at least 4 months.
She would start to get more constructive on the shares with signs of more robust revenue growth, such as indications that BIIB098 will be a big product for Biogen (BIIB), and/or Aristada successfully demonstrating superiority over Invega Sustenna in the ongoing head-to-head trial.
Growth was driven by Stelara, up 36% to $1.3 billion; Zytiga, up 63% to $909 million; Darzalex, up 71% to $511 million; Imbruvica, up 38% to $620 million; Simponi/Simponi Aria, up 25% to $548 million; Invega Sustenna, up 15% to $720 million; and Xarelto, up 6% to $679 million.
schizophrenia patients were randomized to treatment with once-monthly injectable paliperidone palmitate (Invega Sustenna) or daily oral antipsychotics for up to 15 months.
