Description

Aripiprazole is an atypical antipsychotic medication used for the treatment of schizophrenia. It has also recently received FDA approval for the treatment of acute manic and mixed episodes associated with bipolar disorder. Aripiprazole appears to mediate its antipsychotic effects primarily by partial agonism at the D2 receptor. In addition to partial agonist activity at the D2 receptor, aripiprazole is also a partial agonist at the 5-HT1A receptor, and like the other atypical antipsychotics, aripiprazole displays an antagonist profile at the 5-HT2A receptor. Aripiprazole has moderate affinity for histamine and alpha adrenergic receptors, and no appreciable affinity for cholinergic muscarinic receptors. (source: Drug Bank)

Indication

For the treatment of schizophrenia (source: Drug Bank)

Pharmacology, Interactions, and Contraindications

Mechanism Of Action

Aripiprazole exhibits high affinity for dopamine D2 and D3, serotonin 5-HT1A and 5- HT2A receptors, moderate affinity for dopamine D4, serotonin 5-HT2C and 5-HT7, alpha1-adrenergic and histamine H1 receptors and moderate affinity for the serotonin reuptake pump. Aripiprazole has no appreciable affinity for cholinergic muscarinic receptors. Aripiprazole functions as a partial agonist at the dopamine D2 and the serotonin 5-HT1A receptors, and as an antagonist at serotonin 5-HT2A receptor. (source: Drug Bank)

Pharmacology

Aripiprazole is a psychotropic agent belonging to the chemical class of benzisoxazole derivatives and is indicated for the treatment of schizophrenia. Aripiprazole is a selective monoaminergic antagonist with high affinity for the serotonin Type 2 (5HT2), dopamine Type 2 (D2), 1 and 2 adrenergic, and H1 histaminergic receptors. Aripiprazole acts as an antagonist at other receptors, but with lower potency. Antagonism at receptors other than dopamine and 5HT2 with similar receptor affinities may explain some of the other therapeutic and side effects of Aripiprazole. Aripiprazole's antagonism of histamine H1 receptors may explain the somnolence observed with this drug. Aripiprazole's antagonism of adrenergic a1 receptors may explain the orthostatic hypotension observed with this drug. (source: Drug Bank)

  1. rs1800497 at chr11:112776038 in ANKK1
    Phenotype: Compared with patients who had the A2/A2 (C/C) genotype, the positive and negative syndrome scale (PANSS) positive scores of A1/A1 (T/T) patients were 3.71 lower (p = 0.01) and of A1/A2 patients were 1.36 lower (p = 0.03) after 4-week aripiprazole treatment. These results suggest that A1 carriers are associated with superior therapeutic response on positive symptoms. Study size: 128 schizophrenic patients. Study population: Chinese.
