Cariprazine for late-life psychiatric illness: A review on therapeutic potential and challenges

Abstract

Clinicians often face many challenges in the pharmacological treatment of late-life psychiatric illness especially while choosing an antipsychotic drug. The choice of antipsychotic is mostly guided by the extension of evidence from the adult population and tolerability. In India, based on evidence commonly prescribed antipsychotic drugs for older adults are quetiapine (QTP) followed by olanzapine (OLZN) and risperidone. Cariprazine is a newer antipsychotic that was recently launched in India. It is a novel mechanism of action at D3 receptors is known to have antidepressant and procognitive action in addition to the antipsychotic effects which is desirable in geriatric population. It can be a potential option as an add-on drug in late-life depression in addition to the existing aripiprazole and OLZN. The treatment of late-life mania and very late-onset schizophrenia is limited by the paucity of studies, with randomized control studies done only on QTP and amisulpride, respectively. Cariprazine can be considered in late-life psychotic disorders with the evidence available from its efficacy studies in adult patients. Merits of cariprazine are favorable metabolic profile, cardiac safety, and procognitive action. Demerits include extrapyramidal symptoms and fluctuations in blood pressure. Slower titration and monitoring for akathisia are recommended. There is a need for controlled studies in older adults with cariprazine to get better informed about its efficacy and safety.
