Indications/Usage
question
What is Abilify? - Abilify (aripiprazole) is an antipsychotic medication. It works by changing the actions of chemicals in the brain. - Abilify is used to treat the symptoms of psychotic conditions such as schizophrenia and bipolar disorder (manic depression). It is also used together with other medications to treat major depressive disorder in adults. - Abilify is also used to treat irritability and symptoms of aggression, mood swings, temper tantrums, and self-injury related to autistic disorder in children who are at least 6 years old. Important information: - Abilify is not approved for use in psychotic conditions that are related to dementia. Abilify may increase the risk of death in older adults with dementia-related conditions. - Some young people have thoughts about suicide when taking medicine for a major depressive disorder and other psychiatric disorders.

answer
Drug Interactions
question
Taking this medicine with other drugs that make you sleepy can worsen this effect. Ask your doctor before taking Abilify with a sleeping pill, narcotic pain medicine, muscle relaxer, or medicine for anxiety, depression, or seizures. Many other drugs can interact with aripiprazole. This includes prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible interactions are listed here. Tell your doctor about all your medications and any you start or stop using during treatment with this medicine.
answer
What other drugs will affect Abilify?
question
Aripiprazole has not been systematically studied in humans for its potential for abuse, tolerance, or physical dependence. In physical dependence studies in monkeys, withdrawal symptoms were observed upon abrupt cessation of dosing. While the clinical trials did not reveal any tendency for any drug-seeking behavior, these observations were not systematic and it is not possible to predict on the basis of this limited experience the extent to which a CNS-active drug will be misused, diverted, and/or abused once marketed. Consequently, patients should be evaluated carefully for a history of drug abuse, and such patients should be observed closely for signs of Abilify misuse or abuse (e.g., development of tolerance, increases in dose, drug-seeking behavior).
answer
Drug Abuse/Dependence
question
Monitor for clinical worsening of depression, suicidality, unusual changes in behavior, NMS, TD, hyperglycemia, orthostatic hypotension, seizures/convulsions, esophageal dysmotility, aspiration, and other adverse effects. Monitor CBC frequently in patients with preexisting low WBC counts or drug-induced leukopenia/neutropenia. Monitor for fever or other signs/symptoms of infection in patients with neutropenia. Monitor weight regularly and FPG in patients with DM or at risk for DM periodically during therapy. Periodically reassess to determine the continued need for maintenance treatment.
answer
Monitoring Perimeters
question
Partial D2/5HT1A agonist/5HT2A antagonist; not established.
answer
Mechanism of Action
question
Aripiprazole is a psychotropic agent belonging to the chemical class of benzisoxazole derivatives and is indicated for the treatment of schizophrenia. Aripiprazole is a selective monoaminergic antagonist with high affinity for the serotonin Type 2 (5HT2), dopamine Type 2 (D2), 1 and 2 adrenergic, and H1 histaminergic receptors. Aripiprazole acts as an antagonist at other receptors, but with lower potency. Antagonism at receptors other than dopamine and 5HT2 with similar receptor affinities may explain some of the other therapeutic and side effects of Aripiprazole. Aripiprazole's antagonism of histamine H1 receptors may explain the somnolence observed with this drug. Aripiprazole's antagonism of adrenergic a1 receptors may explain the orthostatic hypotension observed with this drug.
answer
Pharmacology
question
Aripiprazole exhibits high affinity for dopamine D2 and D3, serotonin 5-HT1A and 5-HT2A receptors (Ki values of 0.34 nM, 0.8 nM, 1.7 nM, and 3.4 nM, respectively), moderate affinity for dopamine D4, serotonin 5-HT2C and 5-HT7, alpha1-adrenergic and histamine H1 receptors (Ki values of 44 nM, 15 nM, 39 nM, 57 nM, and 61 nM, respectively), and moderate affinity for the serotonin reuptake site (Ki=98 nM). Aripiprazole has no appreciable affinity for cholinergic muscarinic receptors (IC50>1000 nM). Aripiprazole functions as a partial agonist at the dopamine D2 and the serotonin 5-HT1A receptors, and as an antagonist at serotonin 5-HT2A receptor.
answer
Pharmacodynamics
question
- Absorption: Well absorbed, 87% bioavailable. - Peak: 3-5 h. - Metabolism: Metabolized in liver by CYP3A4 and 2D6. Major metabolite, dehydroaripiprazole has some activity. - Elimination: 55% excreted in feces, 25% in urine. - Half-Life: 75 h (94 h for metabolite).
answer
Pharmacokinetics
question
25°C (77°F); excursions permitted to 15-30°C (59-86°F). Oral Sol: May be used for ≤6 months after opening. Inj: Store in original container; protect from light.
answer
Storage/Handling
question
The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.
answer
Disposal Methods
question
Inform about the risks and benefits of treatment. Instruct patients, families, and caregivers to be alert to the emergence of anxiety, agitation, panic attacks, insomnia, irritability, hostility, aggressiveness, impulsivity, akathisia, hypomania, mania, other unusual changes in behavior, worsening of depression, and suicidal ideation; advise to contact physician if these symptoms occur. Instruct to use caution when operating hazardous machinery and to avoid alcohol use while on therapy. Counsel to avoid overheating and dehydration. Advise to notify physician if patient becomes pregnant or intends to become pregnant during therapy, and if patient is taking or plans to take any prescription or OTC drugs. Instruct to not breastfeed during therapy. (Discmelt) Inform phenylketonurics that product contains phenylalanine. Instruct to not open blister until ready to administer. Instruct that drug is to be taken without liquid. However, if needed, drug can be taken with liquid. Advise not to split the tab. (Sol) Inform that sol contains sucrose and fructose.
answer
Patient Education
question
Assessment & Drug Effects: - Monitor diabetics for loss of glycemic control. - Monitor cardiovascular status. Assess for and report orthostatic hypotension. Take BP supine then in sitting position. Report systolic drop of >15-20 mm Hg. Patients at increased risk are those who are dehydrated, hypovolemic, or receiving concurrent antihypertensive therapy. - Monitor body temperature in situations likely to elevate core temperature (e.g., exercising strenuously, exposure to extreme heat, receiving drugs with anticholinergic activity, or being subject to dehydration). - Monitor for and report signs of tardive dyskinesia. - Monitor for and immediately report S&S of neuroleptic malignant syndrome (NMS) that include: hyperpyrexia, muscle rigidity, altered mental status, irregular pulse or blood pressure, tachycardia, diaphoresis, and cardiac dysrhythmia. Withhold drug if NMS is suspected. - Lab tests: Monitor periodically Hct & Hgb. Monitor periodically blood glucose. Monitor for elevated CPK and myoglobinuria if NMS is suspected. Additional Assessment: - Assess for dementia-related psychosis - Drug hypersensitivity - Psychiatric disorders or any other conditions where treatment is cautioned - Pregnancy/nursing status, and possible drug interactions - Obtain baseline FPG in patients with DM or at risk for DM - Obtain baseline CBC if at risk for leukopenia/neutropenia Patient & Family Education: - Carefully monitor blood glucose levels if diabetic. - Do not drive or engage in other potentially hazardous activities until reaction to drug is known. - Avoid situations where you are likely to become overheated or dehydrated. - Notify physician if you become pregnant or intend to become pregnant while taking this drug. - Do not breast feed while taking this drug.
