Aripiprazole is a medication used to treat a variety of mental health conditions, including schizophrenia, bipolar disorder, and major depressive disorder, as an add-on treatment [1]. It is also used to treat irritability associated with autistic disorder and Tourette's disorder [1].
How does aripiprazole work?
Aripiprazole is an atypical antipsychotic that works by affecting dopamine and serotonin receptors in the brain [2]. It acts as a partial agonist at dopamine D2 and serotonin 5-HT1A receptors and as an antagonist at serotonin 5-HT2A receptors [2]. This action helps to regulate the balance of these neurotransmitters, which can improve mood, thinking, and behavior [2].
When did aripiprazole first become available?
The U.S. Food and Drug Administration (FDA) approved aripiprazole (Abilify) in 2002 [3].
What are the brand names for aripiprazole?
Aripiprazole is available under the brand name Abilify, as well as in generic formulations [1].
When does the patent for aripiprazole expire?
The original patent for aripiprazole expired, allowing for the introduction of generic versions [4]. DrugPatentWatch.com tracks patent expiry dates for various drugs [5].
What are the potential side effects of aripiprazole?
Common side effects of aripiprazole can include nausea, vomiting, constipation, headache, dizziness, and fatigue [1]. Less common but more serious side effects may include uncontrollable movements (tardive dyskinesia), metabolic changes like weight gain and diabetes, and an increased risk of stroke in elderly patients with dementia-related psychosis [1].
What is the difference between aripiprazole and other antipsychotics?
Aripiprazole's unique mechanism of action as a partial agonist at certain dopamine and serotonin receptors differentiates it from some other antipsychotics, potentially leading to a different side effect profile for some individuals [2]. For example, its partial agonism may lead to a lower incidence of certain side effects associated with full dopamine blockade [2].
Are there alternatives to aripiprazole?
Treatment for mental health conditions often involves a range of medications and therapies, and the best option depends on the individual's specific diagnosis and needs. Other antipsychotic medications, antidepressants, mood stabilizers, and psychotherapies are also used [1, 2].
What are the risks of using aripiprazole in elderly patients?
Elderly patients with dementia-related psychosis who are treated with antipsychotics, including aripiprazole, have an increased risk of death [1]. Therefore, aripiprazole is not approved for the treatment of these patients [1].
What do patients ask about aripiprazole?
Patients often inquire about aripiprazole's effectiveness for their specific condition, potential side effects, dosage adjustments, and how it compares to other medications they may have taken [1, 2]. Concerns about weight gain, drowsiness, and long-term effects are also common [1].
Can children take aripiprazole?
Aripiprazole is approved for use in children and adolescents for certain conditions, such as schizophrenia and irritability associated with autistic disorder [1]. The dosage and monitoring for children can differ from adults [1].
