摘要
Omeprazole inhibits CYP2C19 and increases citalopram exposure, which raises the risk of dose-related QT prolongation. Labeling limits the citalopram dose when used with CYP2C19 inhibitors.
用白話說明這項交互作用的意義
Citalopram and Omeprazole can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Citalopram belongs to Central Nervous System; Omeprazole belongs to Gastrointestinal Tract.
為什麼會發生
Omeprazole inhibits CYP2C19-mediated metabolism of citalopram.
處置方式
Limit citalopram to 20 mg daily, or use an alternative PPI such as pantoprazole or another antidepressant; monitor ECG and electrolytes in patients at QT risk.
