摘要
Both drugs prolong the QT interval, so combination raises the risk of torsades de pointes and sudden cardiac death. Pimozide labeling and citalopram labeling both caution against or contraindicate co-use with QT-prolonging drugs. Risk is greater at higher citalopram doses and in patients with electrolyte disturbance or cardiac disease.
用白話說明這項交互作用的意義
Citalopram and Pimozide are not normally used together. Taking them at the same time is expected to cause harm or make one of them unsafe, so a different medicine is usually chosen for one of the two.
Citalopram belongs to Central Nervous System; Pimozide belongs to Central Nervous System.
為什麼會發生
Additive QT prolongation. Citalopram is also partly metabolized by CYP2D6 and CYP3A4, and pimozide is a CYP2D6 and CYP3A4 substrate, so pharmacokinetic effects may add to this.
處置方式
Do not co-administer. Choose an antidepressant with less QT effect, such as sertraline, and review the antipsychotic need.
