12.1 Mechanism of Action The mechanism of action of aripiprazole in schizophrenia is unclear. However, the efficacy of aripiprazole in the listed indications could be mediated through a combination of partial agonist activity at D 2 and 5-HT 1A receptors and antagonist activity at 5-HT 2A receptors.

Aripiprazole is indicated for the treatment of: • Schizophrenia • Irritability Associated with Autistic Disorder • Treatment of Tourette’s Disorder Aripiprazole is an atypical antipsychotic. The oral formulations are indicated for: • Schizophrenia (14.1) • Irritability Associated with Autistic Disorder (14.4) • Treatment of Tourette’s disorder (14.5)

Initial Dose Recommended Dose Maximum Dose Schizophrenia – adults (2.1) 10 to 15 mg/day 10 to 15 mg/day 30 mg/day Schizophrenia – adolescents (2.1) 2 mg/day 10 mg/day 30 mg/day Irritability associated with autistic disorder – pediatric patients (2.4) 2 mg/day 5 to 10 mg/day 15 mg/day Tourette’s disorder – (2.5) Patients <50 kg 2 mg/day 5 mg/day 10 mg/day Patients ≥50 kg 2 mg/day 10 mg/day 20 mg/day •Oral formulations: Administer once daily without regard to meals (2) •Known CYP2D6 poor metabolizers: Half of the usual dose (2.7) 2.1 Schizophrenia Adults The recommended starting and target dose for aripiprazole is 10 or 15 mg/day administered on a once-a-day schedule without regard to meals. Aripiprazole has been systematically evaluated and shown to be effective in a dose range of 10 to 30 mg/day, when administered as the tablet formulation; however, doses higher than 10 or 15 mg/day were not more effective than 10 or 15 mg/day. Dosage increases should generally not be made before 2 weeks, the time needed to achieve steady-state [see Clinical Studies (14.1)] . Maintenance Treatment: Maintenance of efficacy in schizophrenia was demonstrated in a trial involving patients with schizophrenia who had been symptomatically stable on other antipsychotic medications for periods of 3 months or longer. These patients were discontinued from those medications and randomized to either aripiprazole 15 mg/day or placebo, and observed for relapse [see Clinical Studies (14.1)] . Patients should be periodically reassessed to determine the continued need for maintenance treatment. Adolescents The recommended target dose of aripiprazole is 10 mg/day. Aripiprazole was studied in adolescent patients 13 to 17 years of age with schizophrenia at daily doses of 10 and 30 mg. The starting daily dose of the tablet formulation in these patients was 2 mg, which was titrated to 5 mg after 2 days and to the target dose of 10 mg after 2 additional days. Subsequent dose increases should be administered in 5 mg increments. The 30 mg/day dose was not shown to be more efficacious than the 10 mg/day dose. Aripiprazole can be administered without regard to meals [see Clinical Studies (14.1)] . Patients should be periodically reassessed to determine the need for maintenance treatment....

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The following are discussed in more detail in other sections of the labeling: • Increased Mortality in Elderly Patients with Dementia-Related Psychosis [see Boxed Warning and (5.1)] • Cerebrovascular Adverse Events, Including Stroke [see (5.2)] • Suicidal Thoughts and Behaviors in Children, Adolescents, and Young Adults [see Boxed Warning and (5.3)] • Neuroleptic Malignant Syndrome (NMS) [see (5.4)] • Tardive Dyskinesia [see (5.5)] • Metabolic Changes [see (5.6)] • Pathological Gambling and Other Compulsive Behaviors [see (5.7)] • Orthostatic Hypotension [see (5.8)] • Falls [see (5.9)] • Leukopenia, Neutropenia, and Agranulocytosis [see (5.10)] • Seizures/Convulsions [see (5.11)] • Potential for Cognitive and Motor Impairment [see (5.12)] • Body Temperature Regulation [see (5.13)] • Suicide [see (5.14)] • Dysphagia [see (5.15)] The most common in adult patients in clinical trials (≥10%) were nausea, vomiting, constipation, headache, dizziness, akathisia, anxiety, insomnia, and restlessness. The most common in the pediatric clinical trials (≥10%) were somnolence, headache, vomiting, extrapyramidal disorder, fatigue, increased appetite, insomnia, nausea, nasopharyngitis, and weight increased. Aripiprazole has been evaluated for safety in 13,543 adult patients who participated in multiple-dose, clinical trials in schizophrenia, other indications, Dementia of the Alzheimer’s type, Parkinson’s disease, and alcoholism, andwho had approximately 7,619 patient-years of exposure to oral aripiprazole and 749 patients with exposure to aripiprazole injection. A total of 3,390 patients were treated with oral aripiprazole for at least 180 days and 1,933 patients treated with oral aripiprazole had at least one year of exposure. Aripiprazole has been evaluated for safety in 1,686 pediatric patients (6 to 18 years) who participated in multiple-dose, clinical trials in schizophrenia, autistic disorder, or Tourette’s disorder or another indication and who had approximately 1,342 patient-years of exposure to oral aripiprazole. A total of 959 pediatric patients were treated with oral aripiprazole for at least 180 days and 556 pediatric patients treated with oral aripiprazole had at least one year of exposure....

Aripiprazole is contraindicated in patients with a history of a hypersensitivity reaction to aripiprazole. Reactions have ranged from pruritus/urticaria to anaphylaxis [see (6.2)]. • Known hypersensitivity to aripiprazole (4)
