        Cariprazine — an Alternative Treatment for Clozapine-resistant Schizophrenia?

        Adam Montgomery(Adam Montgomery ),Marianna Rogowska(Marianna Rogowska ),Luiz Dratcu(Luiz Dratcu ) 대한정신약물학회 2023 CLINICAL PSYCHOPHARMACOLOGY AND NEUROSCIENCE Vol.21 No.1

        Treatment-resistant schizophrenia (TRS) poses a significant therapeutic challenge in psychiatric practice. Clozapine is recognized as a treatment of choice in TRS but is not always effective in alleviating patients’ symptoms. Additionally, clozapine therapy is associated with multiple side effects and monitoring requirements that often limit its use and negatively affect patients’ compliance with the treatment. Although clozapine augmentation options are available, there is currently no alternative monotherapy proven to be effective in TRS. We present a case of a young man with TRS who failed to respond to appropriate trials of risperidone, aripiprazole and also clozapine, and who experienced impairing adverse effects of clozapine that made further clozapine treatment not only futile but also detrimental to his health. He was successfully treated with cariprazine monotherapy, which culminated in the remission of his both positive and negative symptoms of psychosis as well as in the marked improvement in social functioning. Cariprazine, a newer atypical antipsychotic endowed with a D3-preferring mode of action, may offer a better tolerated and more acceptable treatment option for patients with difficult-to-treat psychotic symptoms.

        Clozapine in the Time of COVID-19

        Xavier Boland,Luiz Dratcu 대한정신약물학회 2020 CLINICAL PSYCHOPHARMACOLOGY AND NEUROSCIENCE Vol.18 No.3

        Clozapine is the most effective antipsychotic for treatment resistant schizophrenia but adverse reactions to clozapine include neutropenia. The current COVID-19 pandemic may raise specific concerns for clinicians prescribing clozapine for patients who need it. We report on two actively psychotic patients with treatment resistant schizophrenia who required admission to our inner-London acute psychiatric unit during the COVID-19 pandemic and who were treated with clozapine. One was a young patient who developed COVID-19 symptoms and tested positive for the SARS-CoV-2 virus while receiving clozapine and the other was an aging man who tested negative for the SARS-CoV-2 virus but had contact with COVID-19 during initiation of clozapine treatment. Both responded to clozapine treatment and were safely discharged from hospital without any complication. These cases suggest that, in the absence of complications, exposure to COVID-19 per se and the onset of mild symptoms in those infected may not warrant withdrawal or postponement of clozapine treatment when this is indicated.
