Abilify

Abilify (aripiprazole) is an antipsychotic drug approved to treat symptoms of schizophrenia, autistic disorder, Tourette’s disorder, and episodes of mania or mixed episodes associated with bipolar disorder. The drug works by altering the activity of certain natural substances in the brain. Abilify use has been linked to compulsive gambling, binge eating and uncontrollable sexual urges.

Abilify is an atypical antipsychotic medication, a category that also includes Clozaril (clozapine), Zyprexa (olanzapine) and Risperdal (risperidone), among others. These drugs are called atypical because they differ from the first generation of antipsychotics, such as Haldol (haloperidol) and Thorazine (chlorpromazine). Clozapine, the first atypical antipsychotic, gained approval from the U.S. Food and Drug Administration (FDA) in 1990; typical antipsychotics were developed in the 1950s.

2nd Gen Antipsychotics

Also called second-generation antipsychotics, atypical antipsychotics carry a lower risk of extrapyramidal side effects — or movement disorders, such as Parkinsonism — but a higher risk of metabolic side effects, which include weight gain, high blood sugar, high blood pressure and high cholesterol.

Like typical antipsychotics, atypical antipsychotics block dopamine receptors; however, unlike typical antipsychotics, the newer drugs also affect serotonin, which is the chemical responsible for maintaining mood balance.

Who Manufactures Abilify?

Abilify is available in tablets manufactured by Otsuka Pharmaceutical Co. and in orally disintegrating tablets, oral solution and injections manufactured by Bristol-Myers Squibb Company. Otsuka America Pharmaceutical Inc. distributes and markets Abilify.

Fact

Abilify sales fell in 2015, partly due to generic competition.

Otsuka first partnered with Bristol-Myers Squibb in 1999. Abilify’s utility made it one of the world’s top-grossing and most-prescribed antidepressants. Otsuka’s patent on aripiprazole expired in 2014. The first generic versions were approved in 2015. That same year, Abilify sales fell, in part because of generic competition. Abilify was also being identified as a possible source of impulse-control problems, including compulsive gambling, overeating and uncontrollable sexual urges.

Abilify Uses

The FDA first approved Abilify in 2002 for the treatment of schizophrenia, a mental illness that causes severely disordered thoughts, emotions and behavior as well as a loss of interest in life. Roughly 15 years later, doctors continue to prescribe the antipsychotic for the treatment of schizophrenia in adults and teenagers 13 years of age and older. The drug is not approved to treat schizophrenia in children younger than 13.

Since 2002, the FDA has expanded Abilify’s uses considerably. Most recently, the agency approved the drug to treat children as young as 6 who have Tourette’s disorder, a nervous system disorder that causes uncontrollable movements or sounds known as tics.

Abilify also gained FDA approval for the treatment of irritability associated with autistic disorder, a range of conditions that make it hard to communicate and interact with others. The FDA concluded that Abilify may help control aggression, temper tantrums and frequent mood changes in children ages 6 to 17 with the disorder.

The drug is also approved for use alone or with other medications to treat episodes of mania or mixed episodes in adults and teenagers, and bipolar disorder in children age 10 and older. And when antidepressants alone don’t work, the FDA permits doctors to prescribe Abilify to treat symptoms of major depressive disorder.

Doctors often prescribe Abilify for off-label uses — or uses that lack FDA approval — such as insomnia, delusional disorders and anxiety spectrum disorders. Medical researchers are conducting clinical trials to see if it deserves approval as a treatment for a broader range of maladies.

Abilify Timeline

  • 2002

    The FDA approves Abilify for treatment of schizophrenia after clinical studies of more than 1,000 patients showed that Abilify provided significant improvements in the positive and negative symptoms of schizophrenia.

  • 2005

    Abilify uses expand to include treatment of bipolar disorder after clinical trials demonstrated significant improvement in the symptoms of acute manic or mixed episodes.

  • 2006

    The FDA approves Abilify for adjunct treatment for major depressive disorder after studies demonstrated significant improvement in depressive symptoms in adult patients with a primary diagnosis of major depressive disorder.

  • 2009

    Abilify wins approval as a treatment for irritability associated with autistic disorder based on study results.

  • 2014

    The FDA approves Abilify for treatment of Tourette’s disorder after two trials tested the drug in children with Tourette’s disorder and established efficacy.

How Does Abilify Work?

Atypical or second-generation antipsychotics (SGA) like Abilify work differently from first-generation antipsychotics (FGA) such as Thorazine and Haldol. FGAs target dopamine receptors in the brain, while SGAs typically work on both dopamine and serotonin.

neural receptors
Abilify is an antipsychotic that maintains chemical balances in receptors

Drugs that activate receptors in the brain for these neurotransmitters are called dopamine receptor agonists and serotonin receptor agonists. Compared with older drugs, SGAs have fewer movement side effects, such as tardive dyskinesia, a disorder that causes involuntary movements.

Abilify also works differently from many other SGAs. Other drugs in the class control symptoms by blocking chemical receptors in the brain for dopamine or serotonin. Aripiprazole works by either enhancing dopamine and serotonin levels or inhibiting them to keep a balance. Doctors call the drug a dopamine-serotonin system stabilizer. That effect makes it a useful tool to prescribe alongside other medications to enhance their effectiveness.

Dopamine – What Is It and How Does It Work?

Dopamine is a neurotransmitter, or a chemical released by nerve cells, that is naturally occurring in the brain. This chemical is very important to the proper functioning of the brain and the body. Too little or too much of this organic substance can lead to problems with our mood, sleep, learning, memory, ability to focus, motor control, and the brain’s pleasure and reward centers.

Dopamine nerve cells have cell bodies with nerve fibers that extend to various sites in the brain allowing for transmission of the chemical from one area in the brain to another. These connections help to coordinate movement in the body, aid in problem-solving, complex thinking, memory, intelligence and language, and play an important role in a person’s emotional processing.

Dopamine neurons are also significant in motivation and reward, which explains why substances such as cocaine and nicotine, that act to enhance dopamine levels thereby stimulating the effect of reward receptors in the brain, can become so addictive.

“Despite all of the past research on dopamine, many details are missing on how dopamine acts to produce its effects in the brain,” reported the authors of an editorial published in The American Journal of Psychiatry. But the authors did conclude that when a patient’s dopamine systems are considered dysfunctional, they always “seek a change,” as they simply do not feel “well.”

When a person suffers from a dysfunctional dopamine system such as a resulting dopamine deficiency, they can experience signs and systems of the disorder. These can include a decreased sex drive, tremors (or in extreme cases Parkinson’s disease), weight gain, impaired balance and coordination, and the inability to sit or stand upright, as well as a shift in mood linked to dopamine dysregulation.

On the other hand, when a patient has too much dopamine, sometimes as the result of recreational drugs as well as certain prescription medications like Abilify, they can suffer from overstimulation, addictions, anxiety, insomnia, overactive sex drive and self-destructive behaviors. Excess dopamine is also linked to mental illness, including obsessive-compulsive disorder (OCD), schizophrenia, bipolar disorder, paranoia, hallucinations and psychosis.

What Are the Side Effects of Abilify?

In clinical trials, Abilify patients demonstrated different adverse reactions ranging from movement disorders and tremors to insomnia and fatigue. In addition to warning about minor side effects of the drug, including nausea, headache, dizziness and drooling, the drug’s label cautions that Abilify can also cause serious side effects.

Possible side effects of Abilify include but are not limited to:

  • Suicidal thinking and behavior in children, adolescents and young adults
  • Stroke in elderly people that can lead to death
  • Unusual urges
  • Neuroleptic malignant syndrome (NMS)
  • Uncontrollable body movements (tardive dyskinesia)
  • High blood sugar
  • Increased cholesterol and triglycerides in the blood
  • Weight gain
  • Decreased blood pressure
  • Low white blood cell count
  • Seizures
  • Problems with control of body temperature that could lead to dehydration

Black Box Warnings

Abilify also carries two black box warnings, which the FDA mandates for serious hazards.

Dementia-related Psychosis

One black box warning advises that Abilify is not approved for treatment in elderly patients with dementia-related psychosis.

A review of 17 controlled trials of Abilify and three similar medications — Zyprexa (olanzapine), Risperdal (risperidone) and Seroquel (quetiapine) — found patients treated with the drug died at a rate of about 4.5 percent, compared to a rate of about 2.6 percent in placebo groups.

The other warns of increased risk of suicidal thinking and behavior in children, adolescents and young adults taking antidepressants. This warning is based on the results of trials of nine antidepressant medications, including Abilify.

What Are Abilify’s Dosages and Interactions?

Abilify is available in dosages of 2 mg, 5 mg, 1 mg, 15 mg, 20 mg and 30 mg.

The recommended Abilify dose for treatment of schizophrenia is 10 or 15 mg per day in adults and 10 mg per day in adolescents. The maximum dose for this use is 30 mg per day. The initial dose for adolescents is 2 mg per day.

abilify 10mg pill
abilify 5mg pill
Examples of the Abilify 5mg and 10mg pill

To treat bipolar mania in adults, the recommended dose is 15 mg per day, or 10 to 15 mg per day when used as an adjunct to lithium or valproate. The recommended dose for pediatric patients with bipolar mania is 10 mg per day. Both adult and pediatric patients with bipolar mania should not take more than 30 mg per day. The initial dose for adolescents is 2 mg per day.

For use as adjunctive treatment for major depressive disorder in adults, the initial dose is 2 to 5 mg per day, with adjustments up to 15 mg per day, if necessary. And as a treatment for irritability associated with autistic disorder, the dose for children ages 6 to 17 is 5 to 10 mg per day, with an initial dose of 2 mg per day and a maximum dose of 15 mg per day.

Abilify Dosages

Dosage varies between 2 mg and 20 mg per day based on patient weight for treatment of Tourette’s disorder.

Abilify has interactions with strong CYP3A4 inhibitors, select strong CYP2D6 inhibitors, strong CYP3A4 inducers, antihypertensive drugs and benzodiazepines. Contaminate use of these drugs with Abilify may require dosage adjustments.
