AI Article Synopsis

  • Lurasidon is a new second-generation antipsychotic drug known for its safety and low side effect profile, mainly impacting dopamine and serotonin receptors.
  • A case study is presented involving a 39-year-old man with paranoid schizophrenia who developed neutropenia while taking lurasidone, but his condition improved after discontinuing the drug and receiving supplementation.
  • The findings highlight the importance of regularly monitoring blood cell levels in patients on second-generation antipsychotics to detect risks like neutropenia and agranulocytosis.

Article Abstract

Purpose: Lurasidon is a relatively new, second-generation antipsychotic drug with an interesting receptor profile. It is considered to be safe and has a low risk of side effects. It is a substance with a multi-receptor mechanism of action: it mainly blocks dopaminergic D2 and serotonergic 5-HT2A receptors. According to the Summary of Product Characteristics, the adverse reaction of neutropenia was too rare to enable the estimation of its frequency.

Case Description: A case of 39-year-old patient is presented in the article, diagnosed with paranoid schizophrenia, who developed neutropenia as a result of treatment with lurasidone. After the discontinuation of lurasidone and recommended supplementation, the blood test results gradually improved and finally reached the normal range.

Comment: This case report shows the need for regular monitoring of blood cell parameters in patients treated with second-generation antipsychotics, as there is a risk of neutrocytopenia or even agranulocitosis.
