Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. Cariprazine is not approved for the treatment of patients with dementia-related psychosis.
Antidepressants increased the risk of suicidal thoughts and behavior in pediatric and young adult patients in short-term studies. Closely monitor all antidepressant-treated patients for clinical worsening and for the emergence of suicidal thoughts and behaviors. The safety and efficacy of cariprazine have not been established in pediatric patients.
Note: Due to the long half-life of cariprazine and its active metabolites, changes in dose will not be fully reflected in plasma for several weeks.
Bipolar disorder:
Acute mania and acute episodes with mixed features (monotherapy): Oral: Initial: 1.5 mg once daily; adjust dose based on response and tolerability to 3 mg on day 2 and make further adjustments in increments of 1.5 or 3 mg. Recommended dosing range: 3 mg to 6 mg once daily. Maximum dose: 6 mg/day (product labeling); doses up to 12 mg/day have been evaluated in clinical trials, however, greater efficacy has not been demonstrated (Ref).
Bipolar major depression (monotherapy): Oral: Initial: 1.5 mg once daily; increase based on response and tolerability to 3 mg on day 15. Maximum dose: 3 mg/day (Ref).
Major depressive disorder (unipolar) (adjunctive therapy with antidepressant): Oral: Initial: 1.5 mg once daily, may increase based on response and tolerability to 3 mg once daily on day 15. Maximum dose: 3 mg/day, however, some experts recommend increasing to 4.5 mg/day based on response and tolerability (Ref).
Schizophrenia: Oral: Initial: 1.5 mg once daily; adjust dose based on response and tolerability to 3 mg on day 2 and make further adjustments in increments of 1.5 or 3 mg. Recommended dosing range: 1.5 mg to 6 mg once daily. Maximum dose: 6 mg/day (product labeling); doses up to 9 mg/day have been evaluated in clinical trials, however, greater efficacy has not been demonstrated (Ref).
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
Discontinuation of therapy: In the treatment of chronic psychiatric disease, switching therapy rather than discontinuation is generally advised if side effects are intolerable or treatment is not effective. If patient insists on stopping treatment, gradual dose reduction (ie, over several weeks to months) is advised to detect a re-emergence of symptoms and to avoid withdrawal reactions (eg, agitation, alternating feelings of warmth and chill, anxiety, diaphoresis, dyskinesias, GI symptoms, insomnia, irritability, myalgia, paresthesia, psychosis, restlessness, rhinorrhea, tremor, vertigo) unless discontinuation is due to significant adverse effects. Monitor closely to allow for detection of prodromal symptoms of disease recurrence (Ref).
Switching antipsychotics: An optimal universal strategy for switching antipsychotic drugs has not been established. Strategies include: cross-titration (gradually discontinuing the first antipsychotic while gradually increasing the new antipsychotic) and abrupt change (abruptly discontinuing the first antipsychotic and either increasing the new antipsychotic gradually or starting it at a treatment dose). In patients with schizophrenia at high risk of relapse, the current medication may be maintained at full dose as the new medication is increased (ie, overlap); once the new medication is at therapeutic dose, the first medication is gradually decreased and discontinued over 1 to 2 weeks (Ref). Based upon clinical experience, some experts generally prefer cross-titration and overlap approaches rather than abrupt change (Ref).
CrCl ≥30 mL/minute: No dosage adjustment necessary.
CrCl <30 mL/minute: Use not recommended (has not been studied).
Mild to moderate impairment (Child-Pugh class A or B): No dosage adjustment necessary.
Severe impairment (Child-Pugh class C): Use not recommended (has not been studied).
Note: Avoid for behavioral problems associated with dementia or delirium unless alternative nonpharmacologic therapies have failed and patient may harm self or others. May be appropriate for labeled indications, including schizophrenia or bipolar disorder (Ref).
Refer to adult dosing. Dosages in the lower range of recommended adult dosing are generally sufficient with late-onset schizophrenia or psychosis. Titrate dosage slowly and monitor carefully (Ref).
Both activating effects (eg, akathisia, restlessness) and sedating effects (eg, drowsiness, somnolence) may occur with cariprazine. In clinical studies, most instances of akathisia were considered mild or moderate, though events leading to treatment discontinuation were rarely reported (Ref). The mean duration of akathisia/restlessness in clinical studies was reported between 15 and 24 days (Ref).
Mechanism: Dose-related; sedation from antipsychotics is believed to be due to H1 receptor antagonism; mechanism of activating effects is not clear but is thought to involve GABA and serotonin effects on dopamine signaling (Ref)
Onset: Varied; in clinical studies, akathisia/restlessness most commonly occurred within the first 2 to 6 weeks of therapy (Ref)
Risk factors:
• Akathisia, restlessness: High doses, rapid up-titration (Ref)
• Somnolence: Doses ≥4.5 mg/day (Ref)
• Specific antipsychotic (cariprazine is generally considered to be minimally sedating at usual therapeutic doses in comparison with other antipsychotics) (Ref)
Cariprazine may cause an extrapyramidal reaction, also known as drug-induced movement disorders. Antipsychotics can cause four main extrapyramidal symptoms (EPS): drug-induced parkinsonism, akathisia, acute dystonia, and tardive dyskinesia. EPS presenting as dysphagia, esophageal dysmotility, or aspiration have also been reported with antipsychotics, which may not be recognized as EPS (Ref). In clinical studies, the mean duration of EPS for cases that resolved during study period was ~10 days (Ref).
Mechanism: Dose-related; due to antagonism of dopaminergic D2 receptors in nigrostriatal pathways (cariprazine is a partial agonist) (Ref)
Onset: Intermediate; in clinical studies, acute EPS occurred within the first 3 weeks of therapy (Ref).
Risk factors:
EPS (in general):
• Higher doses (Ref)
• Prior history of EPS (Ref)
Acute dystonia:
• Males (Ref)
• Young age (Ref)
Akathisia:
• Rapid up-titration (Ref)
• Mood disorders (Ref)
• Females (Ref)
• Older patients (Ref)
Drug-induced parkinsonism:
• Higher doses (Ref)
• Older patients (Ref)
• Females (Ref)
• Dementia (Ref)
Tardive dyskinesia:
• Greater total antipsychotic exposure (especially first-generation antipsychotics) (Ref)
• Concomitant treatment with anticholinergic medications (Ref)
• Substance misuse or dependence (Ref)
• Age >55 years (Ref)
• Cognitive impairment (Ref)
• Diabetes (Ref)
• Diagnosis of schizophrenia or affective disorders (Ref)
• Females (Ref)
• History of extrapyramidal symptoms (Ref)
Esophageal dysfunction (associated with EPS):
• Certain comorbidities such as neurologic degenerative disease, dementia, stroke, Parkinson disease, or myasthenia gravis (Ref)
• Older adults >75 years of age (may be risk factor due to age-related muscle atrophy, cognitive impairment, reduced esophageal peristalsis) (Ref)
Leukopenia and neutropenia have been reported with cariprazine. Agranulocytosis has been reported with other second-generation antipsychotics.
Onset: Varied; in general, drug-induced neutropenia usually manifests after 1 or 2 weeks of exposure; however, the onset may be insidious (Ref)
Risk factors:
• Preexisting low white blood cell count or absolute neutrophil count
• History of drug-induced leukopenia or neutropenia
Antipsychotics are associated with hyperglycemia to varying degrees, which is a component of the metabolic syndrome, observed with this pharmacologic class. Cariprazine is associated with a low risk of metabolic alterations; however, increased A1c and blood glucose have been reported with long-term use (Ref).
Mechanism: Mechanism is not entirely understood (Ref)
Risk factors:
Antipsychotics in general:
• African American race (Ref)
• Males (Ref)
• Age <35 years (Ref)
• Preexisting obesity, poor exercise habits, or other risk factors for diabetes, including family history of diabetes (Ref)
• Exposure to other agents that also increase the risk of hyperglycemia (Ref)
• Specific antipsychotic: Metabolic disturbances appear to be the greatest with clozapine and olanzapine and lower with cariprazine (Ref)
Antipsychotics are associated with neuroleptic malignant syndrome (NMS), although the incidence is lower with second-generation (atypical) antipsychotics compared to first-generation (typical) antipsychotics. There is one published case report of NMS with cariprazine (in combination with other psychiatric medications) (Ref).
Mechanism: Non–dose-related; idiosyncratic. Believed to be due to a reduction in CNS dopaminergic tone, along with the dysregulation of autonomic nervous system activity (Ref)
Onset: Varied; in general, most patients develop NMS within 2 weeks of initiating an antipsychotic, and in some patients, prodromal symptoms emerge within hours of initiation; once the syndrome starts, the full syndrome usually develops in 3 to 5 days (Ref). However, there are many cases of NMS occurring months after stable antipsychotic therapy (Ref)
Risk factors:
Antipsychotics in general:
• Males (twice as likely to develop NMS compared to females) (Ref)
• Dehydration (Ref)
• High-dose antipsychotic treatment (Ref)
• Concomitant lithium or benzodiazepine (potential risk factors) (Ref)
• Catatonia (Ref)
• Polypharmacy (Ref)
• Pharmacokinetic interactions (Ref)
• Intramuscular administration (Ref)
• Rapid dosage escalation (Ref)
• Psychomotor agitation (Ref)
Antipsychotics may impair the body's ability to regulate core body temperature, which may cause a potentially life-threatening heat stroke during predisposing conditions, such as heat wave or strenuous exercise.
Risk factors:
Heat stroke (antipsychotics in general):
• Psychiatric illness (regardless of medication use) (Ref)
• Dehydration (Ref)
• Strenuous exercise (Ref)
• Heat exposure (Ref)
• Concomitant medications possessing anticholinergic effects (Ref)
Cariprazine may cause significant weight gain (increase of ≥7% from baseline), which is a component of the metabolic syndrome observed with this pharmacologic class.
Mechanism: Multiple proposed mechanisms, including actions at serotonin, dopamine, histamine, and muscarinic receptors, with differing effects explained by differing affinity of antipsychotics at these receptors (Ref). A low affinity for serotonin and histamine receptors may account for the relatively low risk of weight gain associated with cariprazine (Ref).
Onset: Varied; antipsychotic-induced weight gain usually occurs rapidly in the initial period following initiation, then gradually plateaus over several months with patients continuing to gain weight in the long term (Ref).
Risk factors:
Antipsychotics in general:
• Family history of obesity (Ref)
• Parental BMI (Ref)
• Rapid weight gain in the initial period: Younger age, lower baseline BMI, more robust response to antipsychotic, and increase in appetite; rapid weight gain of >5% in the first month has been observed as the best predictor for significant long-term weight gain (Ref)
• Duration of therapy (although weight gain plateaus, patients continue to gain weight over time) (Ref)
• Schizophrenia (regardless of medication) is associated with a higher prevalence of obesity compared to the general population due to components of the illness, such as negative symptoms, sedentary lifestyles, and unhealthy diets (Ref)
• Specific antipsychotic: Cariprazine is considered to have a minimal or low risk for weight gain; clozapine and olanzapine are considered to have high propensity (Ref)

Canadian labeling: Additional contraindications (not in US labeling): Coadministration with or within 2 weeks of moderate and strong CYP3A4 inhibitors; coadministration with moderate and strong CYP3A4 inducers.
Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
Concerns related to adverse effects:
• Falls: May increase the risk for falls due to somnolence, orthostatic hypotension, and motor or sensory instability.
• Orthostatic hypotension: May cause orthostatic hypotension; risk is increased at initial dose titration and when increasing the dose. Use with caution in patients at risk of this effect or in those who would not tolerate transient hypotensive episodes (patients who are antipsychotic-naive or have cerebrovascular disease, cardiovascular disease, hypovolemia, dehydration, or are taking concurrent medication use which may predispose to hypotension/bradycardia).
Disease-related concerns:
• Dementia: [US Boxed Warning]: Elderly patients with dementia-related psychosis treated with antipsychotics are at an increased risk of death compared to placebo. Most deaths appeared to be either cardiovascular (eg, heart failure, sudden death) or infectious (eg, pneumonia) in nature. Use with caution in patients with Lewy body dementia or Parkinson disease dementia due to greater risk of adverse effects, increased sensitivity to extrapyramidal effects, and association with irreversible cognitive decompensation or death (APA [Reus 2016]). Cariprazine is not approved for the treatment of dementia-related psychosis.
• Hepatic impairment: Use with caution in patients with hepatic impairment; use is not recommended in severe impairment.
• Renal impairment: Use with caution in patients with renal impairment; use is not recommended if CrCl <30 mL/minute.
• Seizures: Use with caution in patients at risk of seizures or with conditions that potentially lower the seizure threshold. Elderly patients may be at increased risk of seizures due to an increased prevalence of predisposing factors.
Other warnings/precautions:
• Discontinuation of therapy: When discontinuing antipsychotic therapy, gradually taper antipsychotics to avoid physical withdrawal symptoms and rebound symptoms (APA [Keepers 2020]; WFSBP [Hasan 2012]). Withdrawal symptoms may include agitation, alternating feelings of warmth and cold, anxiety, diaphoresis, dyskinesia, GI symptoms, insomnia, irritability, myalgia, paresthesia, psychosis, restlessness, rhinorrhea, tremor, and vertigo (Lambert 2007; Moncrieff 2020). The risk of withdrawal symptoms is highest following abrupt discontinuation of highly anticholinergic or dopaminergic antipsychotics (Cerovecki 2013). Patients with chronic symptoms, repeated relapses, and clear diagnostic features of schizophrenia are at risk for poor outcomes if medications are discontinued (APA [Keepers 2020]).
• Pharmacokinetics: Plasma levels of cariprazine and its major metabolites accumulate over time. Adverse reactions may not appear until several weeks after initiation of treatment. Monitor response and for adverse reactions several weeks after the patient has begun treatment and after each dose increase. With treatment discontinuation the plasma concentration of cariprazine and active metabolites declines by 50% in ~1 week; therefore, the decline of plasma concentrations of active drug and metabolite may not be immediately reflected in the patient's clinical symptoms.

Bipolar disorder: Acute treatment of mania or episodes with mixed features and major depression associated with bipolar I disorder.
Major depressive disorder (unipolar): Adjunctive therapy in adults with an inadequate response to antidepressants for the treatment of unipolar major depressive disorder.
Schizophrenia: Treatment of schizophrenia.
Beers Criteria: Antipsychotics are identified in the Beers Criteria as potentially inappropriate medications to be avoided in patients 65 years and older due to an increased risk of stroke and a greater rate of cognitive decline and mortality in patients with dementia. Evidence also suggests there may be an increased risk of mortality with use independent of dementia. Avoid antipsychotics for behavioral problems associated with dementia or delirium unless alternative nonpharmacologic therapies have failed and patient may harm self or others. In addition, antipsychotics should be used with caution in older adults due to their potential to cause or exacerbate syndrome of inappropriate antidiuretic hormone secretion (SIADH) or hyponatremia; monitor sodium closely with initiation or dosage adjustments in older adults. Use of antipsychotics may be appropriate for labeled indications including schizophrenia, bipolar disorder, Parkinson disease psychosis, adjunctive therapy in major depressive disorder, or for short-term use as an antiemetic (Beers Criteria [AGS 2023]).

Antipsychotic use during the third trimester of pregnancy has a risk for abnormal muscle movements (extrapyramidal symptoms [EPS]) and/or withdrawal symptoms in newborns following delivery. Symptoms in the newborn may include agitation, feeding disorder, hypertonia, hypotonia, respiratory distress, somnolence, and tremor; these effects may be self-limiting or require hospitalization.
The ACOG recommends that therapy during pregnancy be individualized; treatment with psychiatric medications during pregnancy should incorporate the clinical expertise of the mental health clinician, obstetrician, primary health care provider, and pediatrician. Safety data related to atypical antipsychotics during pregnancy are limited and routine use is not recommended. However, if a woman is inadvertently exposed to an atypical antipsychotic while pregnant, continuing therapy may be preferable to switching to a typical antipsychotic that the fetus has not yet been exposed to; consider risk:benefit (ACOG 2008).
Health care providers are encouraged to enroll women exposed to cariprazine during pregnancy in the National Pregnancy Registry for Atypical Antipsychotics (866-961-2388 or http://www.womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/).
It is not known if cariprazine is excreted in breast milk. The manufacturer recommends the development and health benefits of breast-feeding be considered along with the mother’s clinical need for therapy and any potential adverse effects on the breast-fed infant.

Timing of serum samples: Draw trough just before next dose (Hiemke 2018).
Therapeutic reference range: 10 to 20 ng/mL (SI: 23.4 to 46.8 nmol/L) (Hiemke 2018). Note: Dosing should be based on therapeutic response as opposed to serum concentrations; however, therapeutic drug monitoring can be used to confirm adherence (APA [Keepers 2020]).
Laboratory alert level: 40 ng/mL (SI: 93.6 nmol/L) (Hiemke 2018).
Cariprazine is a second generation antipsychotic which displays partial agonist activity at dopamine D2 and serotonin 5-HT1A receptors and antagonist activity at serotonin 5-HT2A receptors. It exhibits high affinity for dopamine (D2 and D3) and serotonin (5-HT1A) receptors and has low affinity for serotonin 5-HT2C and alpha1A-adrenergic receptors. Cariprazine functions as an antagonist for 5-HT2B (high affinity) and 5-HT2A receptors (moderate affinity), binds to histamine H1 receptors, and has no affinity for muscarinic (cholinergic) receptors.
Onset of action: Oral:
Bipolar disorder, acute mania: Initial effects may be observed within days of treatment with continued improvements over 1 to 2 weeks (Goikolea 2013; Tohen 2000; Welten 2016).
Bipolar disorder, depressive episode: Initial effects may be observed within 1 week of treatment with continued improvements through 6 weeks (Cruz 2010).
Major depressive disorder, unipolar: Initial effects may be observed within 1 week with continued improvements over 6 to 12 weeks (Wen 2014).
Schizophrenia: Initial effects may be observed within 1 to 2 weeks of treatment with continued improvements through 4 to 6 weeks (Agid 2003; Levine 2010).
Protein binding: 91% to 97%
Metabolism: Extensively metabolized by CYP3A4 and, to a lesser extent, by CYP2D6 to active metabolites (desmethyl cariprazine [DCAR] and didesmethyl cariprazine [DDCAR]). DCAR is further metabolized into DDCAR by CYP3A4 and CYP2D6. DDCAR is then metabolized by CYP3A4 to a hydroxylated metabolite.
Half-life elimination: Cariprazine: 2 to 4 days; DCAR: 1 to 2 days; DDCAR: 1 to 3 weeks
Time to peak, plasma: Cariprazine: 3 to 6 hours
Excretion: Urine (21%; 1.2% as unchanged drug cariprazine)
Note: After multiple dose administration of cariprazine, mean cariprazine and desmethyl cariprazine (DCAR) reached steady state at around week 1 to week 2 and mean didesmethyl cariprazine (DDCAR) appeared to be approaching steady state around week 4 to week 8. After discontinuation, mean cariprazine and DCAR concentration decreased by about 50% in a day and mean DDCAR concentrations decreased by ~50% in 1 week after the last dose. There was an approximately 90% decline in plasma exposure within 1 week for cariprazine and DCAR and at about 4 weeks for DDCAR. Following a single dose of 1 mg of cariprazine, DDCAR remained detectable 8 weeks post-dose.
Hepatic function impairment: Cmax and AUC for cariprazine was increased in patients with mild to moderate hepatic impairment and exposure was decreased for the active metabolites.
