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.

證據等級: High

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.
