摘要
Esomeprazole inhibits CYP2C19, which clears citalopram, so citalopram concentrations rise. Higher exposure increases the risk of dose-related QT prolongation and arrhythmia.
用白話說明這項交互作用的意義
Citalopram and Esomeprazole 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; Esomeprazole belongs to Gastrointestinal Tract.
為什麼會發生
Esomeprazole inhibits CYP2C19, reducing citalopram metabolism.
處置方式
Limit citalopram to 20 mg daily with a CYP2C19 inhibitor. Consider ECG monitoring in patients with other QT risk factors, or use pantoprazole as an alternative PPI.
