Knowra Aripiprazole Aripiprazole Aripiprazole is an atypical antipsychotic medication used for schizophrenia, bipolar disorder, and irritability associated with autism. Its partial agonist activity at dopamine D₂ receptors distinguishes it from many other antipsychotics.
Dopamine D₂ receptor : A G protein-coupled receptor through which dopamine influences movement, motivation, and other brain functions. Aripiprazole partly activates this receptor while limiting its signaling when dopamine activity is high.
Schizophrenia : A mental disorder involving persistent disturbances in thought, perception, emotion, and behavior. Aripiprazole is used to treat schizophrenia symptoms and reduce relapse risk.
Risperidone : An atypical antipsychotic that blocks dopamine D₂ and serotonin 5-HT₂A receptors. Risperidone blocks D₂ receptors more directly, whereas aripiprazole partly activates them.
Antipsychotic : A medication used to treat psychosis and, for some drugs, other psychiatric conditions. Aripiprazole belongs to this broad medication class.
Dopamine partial agonist : A drug that activates dopamine receptors less strongly than dopamine itself. This pharmacological action is central to aripiprazole’s distinctive effect on dopamine signaling.
Bipolar disorder : A mood disorder involving episodes of mania or hypomania and often depression. Aripiprazole is used for acute manic or mixed episodes and for maintenance in some patients.
Quetiapine : An atypical antipsychotic used for schizophrenia, bipolar disorder, and adjunctive depression treatment. Quetiapine has a different receptor profile and commonly causes more sedation.
Pharmacokinetics : The study of how a drug is absorbed, distributed, metabolized, and eliminated by the body. Its long half-life and metabolism shape aripiprazole dosing and interactions.
Serotonin 5-HT₁A receptor : A serotonin receptor involved in regulating mood, anxiety, and neurotransmitter activity. Aripiprazole acts as a partial agonist at this receptor as well as at D₂ receptors.
Autism spectrum disorder : A neurodevelopmental condition involving differences in social communication and restricted or repetitive behaviors. Aripiprazole can reduce associated irritability, including aggression and severe tantrums.
