摘要
Tinidazole is partly metabolized by CYP3A4, and amiodarone is only a weak to moderate CYP3A4 inhibitor, so a significant rise in tinidazole is unlikely. The more relevant concern is that both drugs may prolong the QT interval, with a risk of torsades de pointes.
用白話說明這項交互作用的意義
Amiodarone and Tinidazole can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Amiodarone belongs to Cardiovascular; Tinidazole belongs to Anti Parasitic.
為什麼會發生
Additive QT prolongation, with a minor possible pharmacokinetic effect through CYP3A4 inhibition by amiodarone.
處置方式
Obtain a baseline ECG, keep potassium and magnesium normal, and monitor QTc during co-administration. Consider an alternative antimicrobial if the QTc becomes prolonged.

Can I take Amiodarone with Tinidazole?
MediHelp rates the interaction as moderate. Amiodarone and Tinidazole can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken. Tinidazole is partly metabolized by CYP3A4, and amiodarone is only a weak to moderate CYP3A4 inhibitor, so a significant rise in tinidazole is unlikely. The more relevant concern is that both drugs may prolong the QT interval, with a risk of torsades de pointes.
How serious is the interaction between Amiodarone and Tinidazole?
MediHelp rates it moderate, on a four-level scale (minor, moderate, major, contraindicated) based on published labels and references. What to do, in brief: Obtain a baseline ECG, keep potassium and magnesium normal, and monitor QTc during co-administration. Consider an alternative antimicrobial if the QTc becomes prolonged.
What other medicines interact with Tinidazole?
MediHelp also lists interactions of Tinidazole with, for example, Disulfiram, Ethanol, Fexinidazole. The full list is on the Tinidazole page.
