Pharmacology

Mechanism of Action

Aripiprazole is a quinolinone antipsychotic which exhibits high affinity for D₂, D₃, 5-HT_1A, and 5-HT_2A receptors; moderate affinity for D₄, 5-HT_2C, 5-HT₇, alpha₁ adrenergic, and H₁ receptors. It also possesses moderate affinity for the serotonin reuptake transporter; has no affinity for muscarinic (cholinergic) receptors. Aripiprazole functions as a partial agonist at the D₂ and 5-HT_1A receptors, and as an antagonist at the 5-HT_2A receptor (de Bartolomeis 2015).

Pharmacokinetics/Pharmacodynamics

Absorption

IM: Extended-release: Slow, prolonged

Oral: Well absorbed

Distribution

V_d: 4.9 L/kg

Metabolism

Hepatic dehydrogenation, hydroxylation and N-dealkylation via CYP2D6, CYP3A4 (dehydro-aripiprazole metabolite has affinity for D₂ receptors similar to the parent drug and represents 40% of the parent drug exposure in plasma) (Sheehan 2010)

Excretion

Feces (55%, ~18% of the total dose as unchanged drug; 37% of the total dose as changed drug); urine (25%, <1% of the total dose as unchanged drug; 25% of the total dose as changed drug) (Sheehan 2010)

Onset of Action

Initial: 1 to 3 weeks

Time to Peak

Plasma:

IM: Extended release (after multiple doses): 4 days (deltoid administration); 5 to 7 days (gluteal administration).

Tablet: 3 to 5 hours; high-fat meals delay time to peak by 3 hours for aripiprazole and 12 hours for dehydro-aripiprazole.

Half-Life Elimination

Aripiprazole: 75 hours; dehydro-aripiprazole: 94 hours; IM, extended release (terminal): ~30 to 47 days (dose-dependent)

CYP2D6 poor metabolizers: Aripiprazole: 146 hours

Protein Binding

≥99%, primarily to albumin

Use in Specific Populations

Special Populations: Renal Function Impairment

In severe renal impairment (CrCl <30 mL/minute), C_max increased by 36% (aripiprazole) and 53% (dehydro-aripiprazole), but AUC was 15% lower for aripiprazole and 7% higher for dehydro-aripiprazole.

Special Populations: Hepatic Function Impairment

AUC increased by 31% in mild hepatic impairment and by 8% in moderate impairment, and decreased by 20% in severe impairment.

Use: Off Label

Agitation/aggression (acute, severe) associated with psychiatric disorders (eg, schizophrenia, bipolar disorder), substance intoxication, or other organic causesbyes

Data from a randomized, double-blind, comparator trial and post hoc pooled analysis support the use of aripiprazole in the treatment of agitation associated with schizophrenia and schizoaffective disorders Kinon 2008, Marder 2007.

Based on the World Federation of Societies of Biological Psychiatry (WFSBP) expert consensus for the assessment and management of agitation in psychiatry, oral aripiprazole is effective and recommended in the management of psychomotor agitation associated with psychiatric conditions (eg, schizophrenia, bipolar disorder), substance intoxication, or other organic causes.

Agitation/aggression and psychosis associated with dementia, severe or refractorybyes

Data from randomized, double-blind, placebo-controlled trials support the use of aripiprazole in the treatment psychosis and agitation related to Alzheimer dementia De Deyn 2005, Mintzer 2007, Streim 2008.

Based on the American Psychiatric Association (APA) practice guideline on the use of antipsychotics to treat agitation or psychosis in patients with dementia, antipsychotics, such as aripiprazole, may be considered for the treatment of agitation and psychosis in certain patients; however, evidence for efficacy is modest and use should be limited to patients whose symptoms are dangerous, severe, or cause significant patient distress due to safety risks associated with antipsychotics. Based on the WFSBP guidelines for the treatment of Alzheimer disease and other dementias, drug treatment with aripiprazole for behavioral and psychological aspects (including hyperactivity and psychosis) is recommended, at low doses and for short durations, as a last option after addressing causative factors and using psychosocial interventions.

Delusional disorderc

Data from a limited number of patients studied in case reports suggest that aripiprazole may be beneficial for the treatment of delusional disorder Garg 2014, Iannuzzi 2019, Miyamoto 2008. A systematic review suggests antipsychotics as an effective treatment option Munoz-Negro 2016.

Delusional infestation (delusional parasitosis)c

Data from a limited number of patients studied in case reports suggest that aripiprazole may be beneficial for the treatment of delusional infestation Ladizinski 2010, Yeh 2014. Some experts suggest antipsychotics as an effective treatment option Campbell 2019, Heller 2013.

Huntington disease-associated choreac

Data from a limited number of patients studied suggest that aripiprazole may be beneficial for the treatment of chorea associated with Huntington disease Brusa 2009, Lin 2008, Oulis 2010, Yavuz 2013.

Obsessive-compulsive disorder, treatment resistantcyes

Data from a limited number of patients studied suggest that aripiprazole augmentation of an antidepressant may be beneficial for the treatment of treatment-resistant obsessive-compulsive disorder (OCD) Muscatello 2011, Sayyah 2012.

Based on the APA practice guideline for the treatment of patients with OCD, antipsychotics given as augmentation are recommended in the management of treatment-resistant OCD in patients who have a partial response to initial treatment; however, evidence supporting aripiprazole is limited Koran 2013.

Contraindications

Hypersensitivity (eg, anaphylaxis, pruritus, urticaria) to aripiprazole or any component of the formulation.

Dosage and Administration

Dosing: Adult

Note: Formulations: Available formulations include oral tablets and oral solution supplied as aripiprazole (base) and 2 ER IM injections: aripiprazole monohydrate and aripiprazole lauroxil (see Aripiprazole Lauroxil monograph). All doses are expressed as the equivalent amounts of aripiprazole (base). Aripiprazole tablets are also available with an embedded device that tracks drug ingestion using a smartphone app (Abilify Mycite).

Agitation/aggression (acute, severe) associated with psychiatric disorders (eg, schizophrenia, bipolar disorder), substance intoxication, or other organic causes (alternative agent) (off-label use):

Note: Antipsychotics are appropriate when psychosis is suspected to be the primary cause of agitation/aggression. Other agents are used preferentially in some intoxications (eg, stimulants) or alcohol withdrawal. Depending on presentation, may combine with a benzodiazepine (Moore 2019; WFSBP [Hasan 2012]; Wilson 2012).

Oral: Initial: 10 to 15 mg; may repeat based on response and tolerability every 2 hours up to 30 mg/day (Moore 2019).

Agitation/aggression and psychosis associated with dementia, severe or refractory (alternative agent) (off-label use):

Note: For short-term adjunctive use while addressing underlying causes of severe symptoms (APA [Reus 2016]).

Oral: Initial: 2 to 5 mg once daily; may increase dose based on response and tolerability in 5 mg increments at intervals ≥1 week up to 15 mg once daily. In patients without a clinically significant response after an adequate trial (eg, up to 4 weeks), taper and withdraw therapy. Only continue in patients with a demonstrated benefit and attempt to taper and withdraw at regular intervals; first taper attempt should occur ≤4 months of initiation (APA [Reus 2016]; De Deyn 2005; Mintzer 2007; Streim 2008).

Note: In severe agitation associated with dementia with Lewy bodies, antipsychotics are generally avoided; if use is required, titrating above 2 to 5 mg/day is not recommended (Farlow 2019).

Bipolar disorder:

Oral: Acute manic or mixed episodes (labeled use), acute hypomania (off-label use), and maintenance treatment (labeled use, formulation specific) as monotherapy or adjunctive therapy: Initial: 10 to 15 mg once daily; may increase dose based on response and tolerability in 5 to 10 mg/day increments at intervals of ≥1 week up to a maximum of 30 mg/day (CANMAT [Yatham 2013]; Stovall 2019). Note: Some experts suggest higher initial doses of up to 30 mg/day (Stovall 2019). For maintenance treatment, continue dose and combination regimen that was used to achieve control of the acute episode (CANMAT [Yatham 2013]).

IM, ER injectable suspension (aripiprazole monohydrate) (alternative agent): Maintenance: 400 mg once monthly (doses should be separated by ≥26 days). Note: Establish tolerability with oral aripiprazole prior to initiation of ER injection; due to the prolonged half-life of oral aripiprazole, it may take up to 2 weeks to fully assess tolerability. Continue (overlap) oral aripiprazole or other oral antipsychotic for 14 days during initiation of the ER injection.

Dosage adjustment of ER injection for adverse effects: Consider reducing dose to 300 mg once monthly.

Missed doses of ER injection:

Second or third doses missed:

>4 weeks but <5 weeks since last dose: Administer next dose as soon as possible.

>5 weeks since last dose: Administer oral aripiprazole for 14 days with next injection; adjust oral dose as needed based on response and tolerability.

Fourth or subsequent doses missed:

>4 weeks but <6 weeks since last dose: Administer next dose as soon as possible.

>6 weeks since last dose: Administer oral aripiprazole for 14 days with next injection; adjust oral dose as needed based on response and tolerability.

Delusional disorder (off-label use):

Note: Dosing based on expert opinion:

Oral: Initial: 2 to 5 mg once daily; gradually increase to 10 mg/day; if needed, may further increase dose at intervals of ≥1 to 2 weeks based upon response and tolerability up to 30 mg/day (Manschreck 2019; Miyamoto 2008; Stroup 2019).

Delusional infestation (delusional parasitosis) (off-label use):

Note: Dosing based on expert opinion:

Oral: Initial: 2 mg once daily; may increase dose gradually based on response and tolerability in 2 mg increments at intervals ≥2 weeks up to 12 mg/day (Campbell 2019; Heller 2013; Suh 2019). Some patients may require doses up to 30 mg/day for optimal response. After achieving adequate response, maintain for ≥1 to 3 months before attempting to taper and discontinue (Stroup 2019; Suh 2019).

Huntington disease-associated chorea (alternative agent) (off-label use):

Oral: Initial: 2 mg once daily; may increase dose gradually based on response and tolerability up to a usual range of 7.5 to 15 mg/day (Brusa 2009; Ciammola 2009; Suchowersky 2019).

Major depressive disorder (unipolar), treatment resistant (adjunctive therapy with antidepressant):

Oral: Initial: 2 to 5 mg/day; may increase dose based on response and tolerability in 5 mg increments at intervals ≥1 week up to a manufacturer's maximum of 15 mg/day. A further increase up to 20 mg/day may be necessary in some patients for optimal response (Berman 2009).

Obsessive-compulsive disorder, treatment resistant (adjunctive therapy to antidepressants) (off-label use):

Oral: Initial: 5 mg once daily; may increase dose gradually based on response and tolerability in 5 mg increments at intervals ≥1 week up to 15 mg/day (Ak 2011; APA 2007; Muscatello 2011; Pessina 2009; Sayyah 2012).

Schizophrenia:

Oral: Initial: 10 or 15 mg once daily; may increase dose based on response and tolerability in 5 mg increments at intervals ≥1 week up to a maximum of 30 mg/day (Kane 2009; Khanna 2014; Stroup 2019).

IM, ER injectable suspension (aripiprazole monohydrate): 400 mg once monthly (doses should be separated by ≥26 days). Note: Establish tolerability with oral aripiprazole prior to initiation of the ER injection; due to the prolonged half-life of oral aripiprazole, it may take up to 2 weeks to fully assess tolerability. Continue (overlap) oral aripiprazole or other oral antipsychotic for 14 days during initiation of the ER injection.

Dosage adjustment of ER injection for adverse effects: Consider reducing dose to 300 mg once monthly.

Missed doses of ER injection:

Second or third doses missed:

>4 weeks but <5 weeks since last dose: Administer next dose as soon as possible.

>5 weeks since last dose: Administer oral aripiprazole for 14 days with next injection; adjust oral dose as needed based on response and tolerability.

Fourth or subsequent doses missed:

>4 weeks but <6 weeks since last dose: Administer next dose as soon as possible.

>6 weeks since last dose: Administer oral aripiprazole for 14 days with next injection; adjust oral dose as needed based on response and tolerability.

Dosing conversions:

Orally disintegrating tablets to oral tablet: Orally disintegrating tablets may be substituted for the oral tablet on a mg-per-mg basis.

Oral solution to oral tablet: Oral solution may be substituted for the oral tablet on a mg-per-mg basis, up to 25 mg. Patients receiving 30 mg tablets should be given 25 mg oral solution.

Dosage adjustment based on CYP2D6 metabolizer status:

Oral: Aripiprazole dose should be reduced to 50% of the usual dose in known CYP2D6 poor metabolizers and to 25% of the usual dose in poor metabolizers receiving a concurrent strong CYP3A4 inhibitor (eg, itraconazole, clarithromycin); subsequently adjust dose for favorable response and tolerability.

IM, ER injectable suspension (aripiprazole monohydrate): Reduce aripiprazole dose to 300 mg once monthly in known CYP2D6 poor metabolizers; reduce dose to 200 mg once monthly in CYP2D6 poor metabolizers receiving a concurrent CYP3A4 inhibitor for >14 days. Subsequently adjust dose according to response and tolerability.

Discontinuation of therapy: Gradual dose reduction is advised to avoid withdrawal symptoms (ie, insomnia, headache, GI symptoms) unless discontinuation is due to significant adverse effects. In general, when discontinuing antipsychotic therapy for a chronic psychiatric disorder (eg, bipolar disorder, schizophrenia), decreasing the dose very gradually over weeks to months (eg, reducing the dose by 10% per month) with close monitoring is suggested to allow for detection of prodromal symptoms of disease recurrence (APA [Lehman 2004]; CPA 2005).

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 (Cerovecki 2013; Remington 2005; Takeuchi 2017). Based upon clinical experience, some experts generally prefer cross-titration and overlap approaches rather than abrupt change (Post 2019; Stroup 2019).

Dosing: Geriatric

Refer to adult dosing.

Dosing: Pediatric

Note: Oral solution may be substituted for the oral tablet on a mg-per-mg basis, up to 25 mg. Patients receiving 30 mg tablets should be given 25 mg oral solution. Orally disintegrating tablets (Abilify Discmelt) are bioequivalent to the immediate release tablets (Abilify). Immediate release and extended release parenteral products are not interchangeable.

Attention-deficit/hyperactivity disorder (ADHD): Limited data available: Children ≥8 years and Adolescents: Oral: Initial: 2.5 mg/day; may increase on a weekly basis by 2.5 mg/day increments as tolerated; maximum daily dose: 10 mg/day; dosing based on an open-label, pilot study (n=23, age: 8 to 12 years) which reported significant improvement in ADHD outcome scores without an impact on cognitive measures (positive or negative); mean final dose: 6.7 ± 2.4 mg/day (Findling 2008). Other aripiprazole published reports in pediatric and adolescent patients in which ADHD is a comorbid diagnosis within the study population exist; however, effectiveness in ADHD was not a reported primary outcome measure (Bastiaens 2009; Budman 2008; Findling 2009; Murphy 2009; Valicenti-McDermott 2006).

Autism; treatment of associated irritiability (including aggression, deliberate self-injurious behavior, temper tantrums, and quickly changing moods): Children and Adolescents 6 to 17 years: Oral: Initial: 2 mg daily for 7 days, followed by 5 mg daily; subsequent dose increases may be made in 5 mg increments every ≥7 days, up to a maximum daily dose of 15 mg/day

Bipolar I disorder (acute manic or mixed episodes): Children and Adolescents 10 to 17 years: Oral: Initial: 2 mg daily for 2 days, followed by 5 mg daily for 2 days with a further increase to target dose of 10 mg daily; subsequent dose increases may be made in 5 mg increments, up to a maximum daily dose of 30 mg/day. Note: The safety of doses >30 mg/day has not been evaluated.

Conduct disorder (CD); aggression: Limited data available: Children ≥6 years and Adolescents: Oral: Initial: Patient weight <25 kg: 1 mg/day; 25 to 50 kg: 2 mg/day; 51 to 70 kg: 5 mg/day; >70 kg: 10 mg/day; may titrate after 2 weeks to clinical effectiveness; maximum daily dose: 15 mg/day. Dosing based on an open-label, prospective study (n=23; age: 6 to 17 years) which evaluated pharmacokinetics and effectiveness in patients with a primary diagnosis of CD (with or without comorbid ADHD); results showed improvement in CD symptom scores with only minor improvements in cognition (Findling 2009).

Pervasive Developmental Disorder Not Otherwise Specified (PDD-NOS) or Asperger Disorder; treatment of associated irritability (aggression, self-injury, tantrums): Limited data available: Children ≥4 years and Adolescents: Oral:

Preschool age: Initial dose: 1.25 mg/day with titration every ≥5 days in 1.25 mg/day increments as tolerated or clinically indicated (Masi 2009)

Prepubertal children: Initial dose: 1.25 to 2.5 mg/day with titration every 3 to 5 days in 1.25 to 2.5 mg/day increments as tolerated or clinically indicated; maximum daily dose: 15 mg/day (Masi 2009; Stigler 2009)

Adolescents: Initial dose: 2.5 to 5 mg/day with titration every 5 days in 2.5 to 5 mg/day increments as tolerated or clinically indicated; doses >5 mg/day were divided twice daily; if sleep disorder was reported, the dose was given in morning and/or at lunchtime (Masi 2009); maximum daily dose: 15 mg/day (Stigler 2009)

An open-labeled, pilot study (n=25; mean age: 8.6 years; range: 5 to 17 years) reported an 88% response with a mean final dose of 7.8 mg/day (range: 2.5 to 15 mg/day) (Stigler 2009). A retrospective, noncontrolled, open-label study of 34 PDD patients (mean age: 10.2 years; range: 4 to 15 years) included 10 patients with autistic disorder and 24 patients with PDD-NOS reported a mean final dose: 8.1 ± 4.9 mg/day and an overall response rate of 32.4% (29.2% in patients with PDD-NOS) (Masi 2009). In a retrospective chart review of children and adolescents with developmental disability and a wide range of psychiatric disorders (n=32; age: 5 to 19 years), a mean starting dose of aripiprazole of 7.1 ± 0.32 mg/day and a mean maintenance dose of 10.55 ± 6.9 mg/day was used; a response rate of 56% was reported for the overall population. However, a study population subset analysis in patients with mental retardation (n=18) showed a lower response rate in patients with mental retardation with PDD-NOS (38%) than in patients with mental retardation without PDD-NOS (100%) (Valicenti-McDermott 2006).

Schizophrenia: Adolescents 13 to 17 years: Oral: Initial: 2 mg daily for 2 days, followed by 5 mg daily for 2 days with a further increase to target dose of 10 mg daily; subsequent dose increases may be made in 5 mg increments up to a maximum daily dose of 30 mg/day. Note: 30 mg/day was not found to be more effective than the 10 mg/day dose.

Tourette syndrome, tic disorders: Children ≥6 years and Adolescents: Oral:

Patient weight <50 kg: Initial: 2 mg daily for 2 days, then increase to target dose of 5 mg/day; in patients not achieving optimal control, dose may be further titrated at weekly intervals up to 10 mg/day

Patient weight ≥50 kg: Initial: 2 mg daily for 2 days, then increase to 5 mg/day for 5 days, then increase to target dose of 10 mg/day on day 8 of therapy; in patients not achieving optimal control, dose may be further titrated at weekly intervals in 5 mg/day increments up to 20 mg/day

Discontinuation of therapy: Children and Adolescents: American Academy of Child and Adolescent Psychiatry (AACAP), American Psychiatric Association (APA), Canadian Psychiatric Association (CPA), National Institute for Health and Care Excellence (NICE), and World Federation of Societies of Biological Psychiatry (WFSBP) guidelines recommend gradually tapering antipsychotics to avoid withdrawal symptoms and minimize the risk of relapse (AACAP [McClellan 2007]; APA [Lehman 2004]; Cerovecki 2013; CPA 2005; NICE 2013; WFSBP [Hasan 2012]); risk for withdrawal symptoms may be highest with highly anticholinergic or dopaminergic antipsychotics (Cerovecki 2013). When stopping antipsychotic therapy in patients with schizophrenia, the CPA guidelines recommend a gradual taper over 6 to 24 months and the APA guidelines recommend reducing the dose by 10% each month (APA [Lehman 2004]; CPA 2005). Continuing antiparkinsonism agents for a brief period after discontinuation may prevent withdrawal symptoms (Cerovecki 2013). When switching antipsychotics, three strategies have been suggested: Cross titration (gradually discontinuing the first antipsychotic while gradually increasing the new antipsychotic), overlap and taper (maintaining the dose of the first antipsychotic while gradually increasing the new antipsychotic, then tapering the first antipsychotic), and abrupt change (abruptly discontinuing the first antipsychotic and either increasing the new antipsychotic gradually or starting it at a treatment dose). Evidence supporting ideal switch strategies and taper rates is limited and results are conflicting (Cerovecki 2013; Remington 2005).

Dosage adjustment with concurrent CYP450 inducer or inhibitor therapy:

Oral: Children and Adolescents:

CYP3A4 inducers (eg, carbamazepine, rifampin): Aripiprazole dose should be doubled over 1 to 2 weeks; dose should be subsequently reduced if concurrent inducer agent discontinued.

Strong CYP3A4 inhibitors (eg, ketoconazole): Aripiprazole dose should be reduced to 50% of the usual dose, and proportionally increased upon discontinuation of the inhibitor agent.

CYP2D6 inhibitors (eg, fluoxetine, paroxetine): Aripiprazole dose should be reduced to 50% of the usual dose, and proportionally increased upon discontinuation of the inhibitor agent. Note: When aripiprazole is administered as adjunctive therapy to patients with MDD, the dose should not be adjusted, follow usual dosing recommendations.

CYP3A4 and CYP2D6 inhibitors: Aripiprazole dose should be reduced to 25% of the usual dose. In patients receiving inhibitors of differing (eg, moderate 3A4/strong 2D6) or same (eg, moderate 3A4/moderate 2D6) potencies (excluding concurrent strong inhibitors), further dosage adjustments can be made to achieve the desired clinical response. In patients receiving strong CYP3A4 and 2D6 inhibitors, aripiprazole dose is proportionally increased upon discontinuation of one or both inhibitor agents.

Dosage adjustment based on CYP2D6 metabolizer status:

Oral: Children and Adolescents: Aripiprazole dose should be reduced to 50% of the usual dose in CYP2D6 poor metabolizers and to 25% of the usual dose in poor metabolizers receiving a concurrent strong CYP3A4 inhibitor; subsequently adjust dose for favorable clinical response.

Reconstitution

Injection, powder (extended release):

Prefilled syringe: Reconstitute at room temperature. Rotate the syringe plunger rod to release diluent. Shake vigorously for 20 seconds or until the suspension is uniform; the resulting suspension will be milky white and opaque. (Refer to manufacturer’s labeling for full preparation technique.) Inject full syringe contents immediately following reconstitution.

Vial for reconstitution: Reconstitute using 1.5 mL sterile water for injection (SWFI) (provided) for the 300 mg vial or 1.9 mL SWFI (provided) for the 400 mg vial to a final concentration of 200 mg/mL; residual SWFI should be discarded after reconstitution. Shake vigorously for 30 seconds or until the suspension is uniform; the resulting suspension will be milky white and opaque. If the suspension is not administered immediately after reconstitution, shake vigorously for 60 seconds prior to administration.

Administration

IM: Extended release: For IM use only; do not administer SubQ or IV. Inject slowly into deltoid or gluteal muscle using the appropriate provided needle; for nonobese patients, use the 1-inch (25 mm) needle with deltoid administration or the 1.5-inch (38 mm) needle with gluteal administration; for obese patients, use the 1.5-inch (38 mm) needle with deltoid administration or the 2-inch (51 mm) needle with gluteal administration. Do not massage muscle after administration. Rotate injection sites between the 2 deltoid or gluteal muscles. Administer monthly (doses should be separated by ≥26 days).

Oral: Administer with or without food. Tablet and oral solution may be interchanged on a mg-per-mg basis, up to 25 mg. Doses using 30 mg tablets should be exchanged for 25 mg oral solution. Orally-disintegrating tablets (Abilify Discmelt) are bioequivalent to the IR tablets (Abilify).

Orally-disintegrating tablet: Remove from foil blister by peeling back (do not push tablet through the foil). Place tablet in mouth immediately upon removal. Tablet dissolves rapidly in saliva and may be swallowed without liquid. If needed, can be taken with liquid. Do not split tablet.

Tablet with sensor: Swallow tablets whole; do not divide, crush, or chew. Each tablet is embedded with an ingestible event marker (IEM). The patch that accompanies the tablets is a wearable sensor that detects a signal from the IEM sensor after the tablet is ingested and transmits data to a smartphone within 30 minutes to 2 hours of ingestion. If the detection system fails (ie, tablet is not detected after ingestion), do not repeat the dose. Before use, ensure that the patient is capable and willing to use smartphones and apps, and that the app is compatible with the patient's specific smartphone. Apply patch only when instructed by the app to the left side of the body just above the lower edge of the rib cage. Do not place the patch in areas where the skin is scraped, cracked, inflamed, or irritated, or in a location that overlaps the area of the most recently removed patch. Instruct patients to keep the patch on when showering, swimming, or exercising. The patch should be changed weekly or sooner as needed. The app will prompt patient to change the patch and will direct patient to apply and remove the patch correctly. Patients undergoing an MRI need to remove their patch and replace with a new one as soon as possible. If there is skin irritation, instruct patients to remove the patch. Refer to the information provided in the product packaging and electronic instructions for use with the Mycite app.

Dietary Considerations

Drug Interactions

Abiraterone Acetate: May increase the serum concentration of CYP2D6 Substrates (High risk with Inhibitors). Management: Avoid concurrent use of abiraterone with CYP2D6 substrates that have a narrow therapeutic index whenever possible. When concurrent use is not avoidable, monitor patients closely for signs/symptoms of toxicity. Consider therapy modification

Acetylcholinesterase Inhibitors (Central): May enhance the neurotoxic (central) effect of Antipsychotic Agents. Severe extrapyramidal symptoms have occurred in some patients. Monitor therapy

Ajmaline: May increase the serum concentration of CYP2D6 Substrates (High risk with Inhibitors). Monitor therapy

Warnings/Precautions

Major psychiatric warnings:

• Suicidal thinking/behavior: [US Boxed Warning]: Antidepressants increase the risk of suicidal thinking and behavior in children, adolescents, and young adults (18 to 24 years of age) with major depressive disorder (MDD) and other psychiatric disorders; consider risk prior to prescribing. Short-term studies did not show an increased risk in patients >24 years of age and showed a decreased risk in patients ≥65 years. Closely monitor patients for clinical worsening, suicidality, or unusual changes in behavior, particularly during the initial 1 to 2 months of therapy or during periods of dosage adjustments (increases or decreases); the patient's family or caregiver should be instructed to closely observe the patient and communicate condition with health care provider. A medication guide concerning the use of antidepressants should be dispensed with each prescription. Aripiprazole is not FDA approved for adjunctive treatment of depression in children.

-The possibility of a suicide attempt is inherent in major depression and may persist until remission occurs. Worsening depression and severe abrupt suicidality that are not part of the presenting symptoms may require discontinuation or modification of drug therapy. Use caution in high-risk patients during initiation of therapy. Patients should be screened for bipolar disorder prior to initiation of treatment of major depression.

- Prescriptions should be written for the smallest quantity consistent with good patient care. The patient's family or caregiver should be alerted to monitor patients for the emergence of suicidality and associated behaviors such as anxiety, agitation, panic attacks, insomnia, irritability, hostility, impulsivity, akathisia, hypomania, and mania; patients should be instructed to notify their health care provider if any of these symptoms or worsening depression or psychosis occur.

Concerns related to adverse reactions:

• Altered cardiac conduction: May alter cardiac conduction; life-threatening arrhythmias have occurred with therapeutic doses of antipsychotics.
• Blood dyscrasias: Leukopenia, neutropenia, and agranulocytosis (sometimes fatal) have been reported in clinical trials and postmarketing reports with antipsychotic use; presence of risk factors (eg, preexisting low WBC/ANC or history of drug-induced leuko-/neutropenia) should prompt periodic blood count assessment. Discontinue therapy at first signs of blood dyscrasias or if absolute neutrophil count <1,000/mm³.
• Cerebrovascular effects: An increased incidence of cerebrovascular effects (eg, transient ischemic attack, stroke), including fatalities, has been reported in placebo-controlled trials of aripiprazole for the unapproved use in elderly patients with dementia-related psychosis.
• CNS depression: May cause CNS depression, which may impair physical or mental abilities; patients must be cautioned about performing tasks that require mental alertness (eg, operating machinery, driving).
• Dyslipidemia: Has been reported with atypical antipsychotics; risk profile may differ between agents. In clinical trials, lipid changes observed with aripiprazole monotherapy were similar to those observed with placebo.
• Esophageal dysmotility/aspiration: Antipsychotic use has been associated with esophageal dysmotility and aspiration; risk increases with age. Use with caution in patients at risk for aspiration pneumonia (eg, Alzheimer dementia), particularly in patients >75 years (Herzig 2017; Maddalena 2004).
• Extrapyramidal symptoms: May cause extrapyramidal symptoms (EPS), including pseudoparkinsonism, acute dystonic reactions, akathisia, and tardive dyskinesia (risk of these reactions is generally much lower relative to typical/conventional antipsychotics; frequencies reported are similar to placebo). Risk of dystonia (and probably other EPS) may be greater with increased doses, use of conventional antipsychotics, males, and younger patients. Factors associated with greater vulnerability to tardive dyskinesia include older in age, female gender combined with postmenopausal status, Parkinson disease, pseudoparkinsonism symptoms, affective disorders (particularly major depressive disorder), concurrent medical diseases such as diabetes, previous brain damage, alcoholism, poor treatment response, and use of high doses of antipsychotics (APA [Lehman 2004]; Soares-Weiser 2007). Consider therapy discontinuation with signs/symptoms of tardive dyskinesia.
• Falls: May increase the risk for falls due to somnolence, orthostatic hypotension and motor or sensory instability. Complete fall risk assessments at baseline and periodically during treatment in patients with diseases or on medications that may also increase fall risk.
• Hyperglycemia: Atypical antipsychotics have been associated with development of hyperglycemia; in some cases, may be extreme and associated with ketoacidosis, hyperosmolar coma, or death. Use with caution in patients with diabetes or other disorders of glucose regulation; monitor for worsening of glucose control. Patients with risk factors for diabetes (eg, obesity or family history) should have a baseline fasting blood sugar and periodic assessment of glucose regulation. Reports of hyperglycemia with aripiprazole therapy have been few and specific risk associated with this agent is not known.
• Impulse control disorders: Has been associated with compulsive behaviors and/or loss of impulse control, which has manifested as pathological gambling, uncontrolled sexual urges, uncontrolled spending, binge or compulsive eating, and/or other intense urges. Patients with prior history of impulse control issues may be at increased risk. Dose reduction or discontinuation of therapy has been reported to reverse these behaviors in most, but not all, cases (Gaboriau 2014; Moore 2014; Smith 2011).
• Neuroleptic malignant syndrome: Use may be associated with neuroleptic malignant syndrome; monitor for mental status changes, fever, muscle rigidity and/or autonomic instability.
• Orthostatic hypotension: May cause orthostatic hypotension; use with caution in patients at risk of this effect or in those who would not tolerate transient hypotensive episodes (cerebrovascular disease, cardiovascular disease, hypovolemia, or concurrent medication use which may predispose to hypotension/bradycardia).
• Temperature regulation: Impaired core body temperature regulation may occur; caution with strenuous exercise, heat exposure, dehydration, and concomitant medication possessing anticholinergic effects.
• Weight gain: Significant weight gain (>7% of baseline weight) has been observed with antipsychotic therapy; incidence varies with product. Monitor waist circumference and BMI.

Disease-related concerns:

• Cardiovascular disease: Use with caution in patients with cardiac disease, cerebrovascular disease, prior myocardial infarction, ischemic heart disease, or conditions which predispose to hypotension.
• 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]). Aripiprazole is not approved for the treatment of dementia-related psychosis.
• Parkinson disease: Use with caution in patients with Parkinson disease; antipsychotics may aggravate motor disturbances (APA [Lehman 2004; APA [Reus 2016]).
• Seizures: Use with caution in patients at risk of seizures, including those with a history of seizures, head trauma, brain damage, alcoholism, or concurrent therapy with medications which may lower seizure threshold. Elderly patients may be at increased risk of seizures due to an increased prevalence of predisposing factors.

Concurrent drug therapy issues:

• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.

Dosage form specific issues:

• Lactose: Tablets may contain lactose; avoid use in patients with galactose intolerance or glucose-galactose malabsorption.
• Phenylalanine: Orally-disintegrating tablets may contain phenylalanine.
• Product interchangeability: Injection There are 2 ER formulations available for IM administration: Aripiprazole monohydrate (Abilify Maintena) and aripiprazole lauroxil (Aristada and Aristada Initio).
• Tablet with sensor: The ability of aripiprazole tablets with sensor to improve patient compliance or modify aripiprazole dosage has not been established. The use of aripiprazole tablets with sensor to track drug ingestion in “real time” or during an emergency is not recommended because detection may be delayed or not occur.

Other warnings/precautions:

• Discontinuation of therapy: When discontinuing antipsychotic therapy, the American Psychiatric Association (APA), Canadian Psychiatric Association (CPA), and World Federation of Societies of Biological Psychiatry (WFSBP) guidelines recommend gradually tapering antipsychotics to avoid physical withdrawal symptoms, including anorexia, anxiety, diaphoresis, diarrhea, dizziness, dyskinesia, headache, myalgia, nausea, paresthesia, restlessness, tremulousness and vomiting (APA [Lehman 2004]; CPA [Addington 2005]; Lambert 2007; WFSBP [Hasan 2012]). The risk of withdrawal symptoms is highest following abrupt discontinuation of highly anticholinergic or dopaminergic antipsychotics (Cerovecki 2013). Additional factors such as duration of antipsychotic exposure, the indication for use, medication half-life and risk for relapse should be considered. In schizophrenia, there is no reliable indicator to differentiate the minority who will not from the majority who will relapse with drug discontinuation. However, studies in which the medication of well-stabilized patients were discontinued indicate that 75% of patients relapse within 6 to 24 months. Indefinite maintenance antipsychotic medication is generally recommended, and especially for patients who have had multiple prior episodes or two episodes within 5 years (APA [Lehman 2004]).

Monitoring Parameters

Mental status; vital signs (as clinically indicated); blood pressure (baseline; repeat 3 months after antipsychotic initiation, then yearly); weight, height, BMI, waist circumference (baseline; repeat at 4, 8, and 12 weeks after initiating or changing therapy, then quarterly; consider switching to a different antipsychotic for a weight gain ≥5% of initial weight); CBC (as clinically indicated; monitor frequently during the first few months of therapy in patients with preexisting low WBC or history of drug-induced leukopenia/neutropenia); electrolytes and liver function (annually and as clinically indicated); personal and family history of obesity, diabetes, dyslipidemia, hypertension, or cardiovascular disease (baseline; repeat annually); fasting plasma glucose level/HbA_1c (baseline; repeat 3 months after starting antipsychotic, then yearly); fasting lipid panel (baseline; repeat 3 months after initiation of antipsychotic; if LDL level is normal repeat at 2- to 5-year intervals or more frequently if clinical indicated); changes in menstruation, libido, development of galactorrhea, erectile and ejaculatory function (yearly); abnormal involuntary movements or parkinsonian signs (baseline; repeat weekly until dose stabilized for at least 2 weeks after introduction and for 2 weeks after any significant dose increase); tardive dyskinesia (every 12 months; high-risk patients every 6 months); ocular examination (yearly in patients >40 years; every 2 years in younger patients) (ADA 2004; Lehman 2004; Marder 2004).

Pregnancy

Pregnancy Considerations

Aripiprazole crosses the placenta; aripiprazole and dehydro-aripiprazole can be detected in the cord blood at delivery (Nguyen 2011; Watanabe 2011).

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.

Treatment algorithms have been developed by the ACOG and the APA for the management of depression in women prior to conception and during pregnancy (Yonkers 2009). 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 is limited, as such, 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 an agent that the fetus has not yet been exposed to; consider risk:benefit (ACOG 2008). If treatment is needed in a woman planning a pregnancy or if treatment is initiated during pregnancy, use of an agent other than aripiprazole is preferred (Larsen 2015).

Health care providers are encouraged to enroll women exposed to aripiprazole during pregnancy in the National Pregnancy Registry for Atypical Antipsychotics (866-961-2388 or http://www.womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/).
