ストレスによる薬物動態の変化は,本薬のようないくつかの薬物の血漿中濃度を著しく変化させる可能性がある。本報告は、統合失調感情障害、双極性障害タイプの中年男性の症例で、本薬投与中止後3日後に本薬濃度の持続的な上昇を示した。本剤投与前に急性細菌性肺炎と急性細菌性髄膜炎を発症し,精神病と攻撃的行動の悪化でハロペリドールを複数回静脈内投与した後,神経遮断性悪性症候群を発症していた。また、このトピックに関する既存の文献をレビューし、急性炎症性ストレスおよび神経弛緩性悪性症候群の間にクロザピン濃度が持続する可能性のある理由を検討した。
Stress-induced changes in pharmacokinetics can significantly alter the plasma levels of some drugs such as clozapine. This report describes the case of a middle-aged man with schizoaffective disorder, bipolar type who showed sustained elevation in clozapine levels 3 days after discontinuation. Before the clozapine levels were drawn, he had developed acute bacterial pneumonia and signs of acute bacterial meningitis followed by neuroleptic malignant syndrome after he received multiple doses of intravenous haloperidol for worsening psychosis and aggressive behavior. Existing literature on this topic is also reviewed to investigate potential reasons for sustained clozapine levels during acute inflammatory stress and neuroleptic malignant syndrome.
