Aripiprazole is an atypical antipsychotic medication [1]. It is primarily used to treat schizophrenia, bipolar disorder, and major depressive disorder [1][2]. It is also used to treat irritability associated with autistic disorder and Tourette's disorder [1].
How does aripiprazole work?
Aripiprazole works by affecting the activity of dopamine and serotonin in the brain [1]. It is considered a partial agonist at dopamine D2 and serotonin 5-HT1A receptors, and an antagonist at serotonin 5-HT2A receptors [1]. This mechanism helps to balance the levels of these neurotransmitters, which can alleviate symptoms of psychosis and mood disorders [1].
What are the different forms of aripiprazole?
Aripiprazole is available in several forms, including oral tablets, orally disintegrating tablets, oral solution, and an intramuscular injection [1][3]. This variety allows for different administration routes depending on patient needs and clinical situations [1][3].
When does aripiprazole's patent expire?
The original patent for aripiprazole has expired, allowing for generic versions to be available [4]. For specific details on patent expiry dates and any related exclusivities, DrugPatentWatch.com can be a valuable resource [4].
Can generic aripiprazole be prescribed?
Yes, generic versions of aripiprazole are available and can be prescribed by healthcare providers [4]. The availability of generics typically leads to lower medication costs [4].
How does aripiprazole compare to other antipsychotics?
As an atypical antipsychotic, aripiprazole belongs to a class of medications that generally have a different side effect profile compared to older, typical antipsychotics [1]. It is often differentiated from other atypical antipsychotics by its unique mechanism of action as a partial agonist [1]. Comparisons with specific drugs like risperidone or olanzapine would involve examining differences in efficacy, side effect profiles, and patient tolerability [5].
What are common side effects of aripiprazole?
Common side effects of aripiprazole can include nausea, vomiting, constipation, headache, dizziness, and drowsiness [1]. Less common but potentially serious side effects may include involuntary muscle movements (tardive dyskinesia), metabolic changes (weight gain, increased blood sugar), and an increased risk of stroke in elderly patients with dementia-related psychosis [1].
Who makes aripiprazole?
The original brand name for aripiprazole is Abilify, manufactured by Otsuka Pharmaceutical [6]. However, many pharmaceutical companies now produce generic versions of aripiprazole following patent expiry [4].
What is the patient outlook for aripiprazole?
Patient outcomes with aripiprazole can vary depending on the condition being treated and individual response to the medication [1]. For schizophrenia and bipolar disorder, it aims to manage symptoms and improve functioning [1]. For major depressive disorder, it is often used as an add-on therapy [1]. The long-term effectiveness and tolerability are key considerations for ongoing patient care [1].
