Aripiprazole (28x15mg)

Aripiprazole, 3rd generation Antipsychotic

Aripiprazole, sold under the brand name Abilify, among others, is a unique atypical antipsychotic primarily used in the treatment of schizophrenia, mania in bipolar disorder, and irritability associated with autism spectrum disorder; other uses include as an add-on treatment for major depressive disorder, obsessive–compulsive disorder, and tic disorders. Aripiprazole is taken by mouth or via injection into a muscle.

It has generally favorable tolerability. Common side effects include restlessness, insomnia, transient weight gain, nausea, vomiting, constipation, dizziness, and mild sedation. Serious side effects may include neuroleptic malignant syndrome, tardive dyskinesia, and anaphylaxis. It is not recommended for older people with dementia-related psychosis due to an increased risk of death. In pregnancy, there is evidence of possible harm to the fetus. It is not recommended in women who are breastfeeding. It has not been very well studied in people younger than 18.

Aripiprazole is a pharmacologically unique atypical antipsychotic whose principal pharmacological action is as a functionally selective partial agonist at dopamine D2 receptors, stabilizing dopamine activity by enhancing signaling when levels are low and reducing it when levels are high. It also acts as a partial agonist at dopamine D3 and D4 receptors and at serotonin 5-HT1A and 5-HT2C receptors. It is a third-generation antipsychotic and its introduction led to a paradigm shift in antipsychotic drug development.
