What is it?

Abilify is a medicine that contains the active substance aripiprazole. It is available as tablets (rectangular and blue: 5 mg; rectangular and pink: 10 mg; round and yellow: 15 mg; round and pink: 30 mg), round, orodispersible tablets (tablets that dissolve in the mouth; pink: 10 and 30 mg; yellow: 15 mg), an oral solution (1 mg/ml) and a solution for injection (7.5 mg/ml).

What is it used for?

Abilify is used in patients with the following mental illnesses:
- schizophrenia, a mental illness with a number of symptoms, including disorganised thinking and speech, hallucinations (hearing or seeing things that are not there), suspiciousness and delusions (false beliefs). Abilify is used to treat patients aged 15 years or over;
- bipolar I disorder, a mental illness in which patients have manic episodes (periods of abnormally high mood), alternating with periods of normal mood. They may also have episodes of depression. Abilify is used to treat moderate to severe manic episodes and to prevent manic episodes in patients who have responded to the medicine in the past. Abilify is used in adults (aged 18 years or over).
The solution for injection is used for the rapid control of agitation or disturbed behaviour in adults when taking the medicine by mouth is not appropriate.
The medicine can only be obtained with a prescription.


How is it used?

For schizophrenia, the recommended starting dose is 10 or 15 mg by mouth per day in adults, followed by a ?maintenance? dose of 15 mg once a day. In patients aged between 15 and 17 years, the starting dose is 2 mg a day, which is gradually increased to the recommended dose of 10 mg once a day. For bipolar disorder, the recommended starting dose is 15 mg by mouth once a day, either on its own or in combination with other medicines. To prevent manic episodes, the same dose should be continued. For both illnesses, higher doses may benefit some patients.
The oral solution or orodispersible tablets can be used in patients who have difficulty swallowing tablets. The orodispersible tablets are taken by being placed on the tongue, where they disintegrate quickly in the saliva, or by mixing them in water before swallowing. The solution for injection is only for short-term use in adults and should be replaced by the tablets, orodispersible tablets or oral solution as soon as possible: the usual dose is 9.75 mg as a single injection into the shoulder or buttock muscle, but effective doses range between 5.25 and 15 mg. A second injection can be given from two hours after the first if necessary, but no more than three injections should be given in any 24-hour period.
Abilify can be taken with or without food. The dose should not exceed 30 mg a day. The dose of Abilify should be adjusted in patients who are taking other medicines that are broken down in the same way as Abilify. For more information, see the Package Leaflet.

How does it work?

The active substance in Abilify, aripiprazole, is an antipsychotic medicine. Its exact mechanism of action is unknown, but it attaches to several different receptors on the surface of nerve cells in the brain. This disrupts signals transmitted between brain cells by ?neurotransmitters?, chemicals that allow nerve cells to communicate with each other. Aripiprazole is thought to act mainly by being a ?partial agonist? for the receptors for the neurotransmitters dopamine and 5-hydroxytryptamine (also called serotonin). This means that aripiprazole acts like dopamine and 5-hydroxytryptamine by activating these receptors, but less strongly than the neurotransmitters. Since dopamine and 5-hydroxytryptamine are involved in schizophrenia and bipolar disorder, aripiprazole helps to normalise the activity of the brain, reducing psychotic or manic symptoms and preventing them from returning.

How has it been studied?

For the treatment of schizophrenia, there were three main short-term studies lasting four to six weeks, which involved 1,203 adults and compared Abilify tablets with placebo (a dummy treatment). The effectiveness of Abilify in preventing symptoms from returning was assessed in three studies lasting up to a year, two of which used haloperidol (another antipsychotic medicine) as a comparator. Abilify tablets were also compared with placebo in one study involving 302 patients aged between 13 and 17 years. The solution for injection was compared with placebo over a period of two hours in two studies involving 805 adults with schizophrenia or related conditions who were experiencing symptoms of agitation. All of the studies measured the change in the patient?s symptoms using a standard scale for schizophrenia.
For the treatment of bipolar disorder, there were eight main studies looking at Abilify taken by mouth. Five of these compared Abilify with placebo over three weeks in a total of 1,900 patients, two of which continued for a further nine weeks to look at the maintenance of the effect and used haloperidol and lithium (another antipsychotic medicine) as comparators. The sixth study compared Abilify with haloperidol over 12 weeks in 347 patients, and the seventh compared Abilify with placebo in the prevention of recurrence in 160 patients whose manic symptoms had already been stabilised using Abilify. The eighth study looked at the effect of adding Abilify or placebo to existing treatment with lithium or valproate (another antipsychotic medicine) in 384 patients. Abilify solution for injection was compared with lorazepam (another antipsychotic medicine) and placebo over two hours in one study involving 301 patients experiencing symptoms of agitation. All of these studies looked at the change in symptoms using a standard scale for bipolar disorder or at the number of patients who responded to treatment.
The company also carried out studies looking at the absorption of the orodispersible tablets and oral solution by the body.

What benefits has it shown during the studies?

When used to treat schizophrenia, Abilify was more effective than placebo in the short-term adult studies. In the long-term studies, Abilify was more effective than placebo, and as effective as haloperidol, after up to a year of treatment. Abilify was also more effective than placebo over six weeks in the study of adolescents, and the effect of Abilify was maintained for at least six months in patients aged over 15 years. In both studies of the solution for injection, patients receiving Abilify had a greater reduction in symptoms of agitation than those receiving placebo.
When used to treat bipolar disorder, Abilify was more effective than placebo at reducing manic symptoms in four of the five short-term studies. Abilify also had a similar effect to haloperidol and to lithium over three weeks. This effect was maintained for up to 12 weeks. Abilify was also more effective than placebo at preventing manic episodes returning in previously treated patients for up to 74 weeks, and when it was used as an add-on to existing treatment. Injections of Abilify were also more effective than placebo in reducing the symptoms of agitation, and were of similar effectiveness to lorazepam.

What is the risk associated?

In adults, the most common side effects when taking Abilify by mouth (seen in between 1 and 10 patients in 100) are restlessness, insomnia (difficulty sleeping), anxiety, extrapyramidal disorder (uncontrolled twitching or jerking), akathisia (a constant urge to move), tremor (shaking), dizziness, somnolence (sleepiness), sedation (drowsiness), headache, blurred vision, dyspepsia (heartburn), vomiting, nausea (feeling sick), constipation, salivary hypersecretion (increased production of saliva) and fatigue (tiredness). Akathisia is more common in patients with bipolar disorder than in those with schizophrenia. The side effects are similar in adolescents, but somnolence, sedation and extrapyramidal disorder are more common than in adults. The most common side effects with the injection (seen in between 1 and 10 patients in 100) are somnolence, dizziness, headache, akathisia, nausea and vomiting. For the full list of all side effects reported with Abilify, see the Package Leaflet. Abilify should not be used in people who may be hypersensitive (allergic) to aripiprazole or any of the other ingredients.

Why has it been approved?

The Committee for Medicinal Products for Human Use (CHMP) decided that Abilify?s benefits are greater than its risks for the treatment of schizophrenia in adults and in adolescents 15 years and older and of moderate to severe manic episodes in bipolar I disorder, and for the prevention of a new manic episode in patients who experienced predominantly manic episodes and whose manic episodes responded to aripiprazole treatment. The CHMP also decided that the benefits of the solution for injection are greater than its risks for the rapid control of agitation and disturbed behaviours in patients with schizophrenia or in patients with manic episodes in bipolar I disorder, when oral therapy is not appropriate. The Committee recommended that Abilify be given marketing authorisation.
