Catatonia is a widespread problem in psychiatric hospitals as approximately 10% of patients present with catatonic symptoms upon admission. Catatonia carries the risk of severe, even fatal complications. The first line treatment is usually electroconvulsive therapy (ECT) or benzodiazepines, but ECT may not be readily available and benzodiazepines may not always be effective. We describe the case of a patient presenting with severe symptoms of catatonic depression who completed a 3-day course of 25 mg aripiprazole that rapidly resolved his catatonic symptoms. Several cases have already been reported where administration of aripiprazole successfully resolved catatonic symptoms after other treatment options had failed. Aripiprazole’s efficacy and advantages may lie in its unique receptor profile. It acts as a dopamine D2 receptor (D2 R) antagonist and partial D2 R agonist depending on the precise cellular milieu, which may explain its efficacy and favourable side effect profile compared to other antipsychotics used to treat catatonia. Aripiprazole also partially agonises D3 receptors and serotonin 2 C receptors (5-HT2 C), which may contribute to its antidepressant properties. Aripiprazole enhances gamma-aminobutyric acid (GABA) transmission in certain brain areas, and it is widely agreed that low GABA activity may contribute to catatonic symptoms. Pharmacokinetics studies show that peak plasma levels are reached rapidly, within 2–3 hours of intramuscular administration and 4–6 hours of oral administration. Administration of high-dose aripiprazole (>25 mg/day) should be considered as a viable alternative to ECT and benzodiazepines in patients presenting with catatonic symptoms. Aripiprazole also carries a much lower risk of complications compared to other antipsychotics.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
