Amiodarone and Ciprofloxacin: what the published research says

PubMed indexes 4 records that name Amiodarone and Ciprofloxacin together, either in the title or in an interaction, co-administration, or pharmacokinetic context. Each one is listed below with its study design and, where the abstract states one, the authors’ own conclusion, quoted and linked. This page reports that literature. It does not tell you whether to combine them.

Read this first

An evidence index, not guidance.

Every statement below is attributed to a named, dated, linked source.

This page lists published research relevant to Amiodarone and Ciprofloxacin. It deliberately does not state whether the combination is safe, whether it interacts, in which direction, at what dose, or how far apart to take them.

The research

4 studies naming Amiodarone and Ciprofloxacin.

Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.

Adverse Drug Events in Patients with Chronic Kidney Disease Associated with Multiple Drug Interactions and Polypharmacy.

Drugs & aging · 2020 · PMID 32056163

Observational StudyHuman subjects

“Multiple pharmacodynamic interactions related to QTc prolongation, hyperkalaemia and haemorrhage are frequently associated with a negative outcome in older adults with CKD and often require recurrent medical treatment or rehospitalization.”

Sommer et al. · Authors' conclusion

Names Amiodarone and Ciprofloxacin together in an interaction, co-administration, or pharmacokinetic context.

Unexpected complication following esophageal variceal hemorrhage - Case 2/2011

Deutsche medizinische Wochenschrift (1946) · 2011 · PMID 21271486

Case ReportsHuman subjects

“Secondary torsades de pointes tachycardias have a low incidence, but often fatal outcome. Torsades de pointes tachycardias mostly are the result of administration of QT-active drugs, and other cofactors. Emergency treatment addresses the reestablishment, and stabilization of sinus rhythm. Preferably, drug-induced torsades de pointes tachycardias are prevented by permanent critical review of administered drugs with respect to indications, interactions, and adverse reactions.”

Werner et al. · Authors' conclusion

Names Amiodarone and Ciprofloxacin together in an interaction, co-administration, or pharmacokinetic context.

Ciprofloxacin-induced acquired long QT syndrome.

Heart rhythm · 2004 · PMID 15851230

Case ReportsHuman subjects

“Ciprofloxacin may cause QTc prolongation and rarely torsades de pointes. This effect is of particular concern in patients with predisposing factors, such as concomitant medications or underlying heart disease reflecting decreased repolarization reserve.”

Prabhakar et al. · From the abstract

Names Amiodarone and Ciprofloxacin together in an interaction, co-administration, or pharmacokinetic context.

Limitations

What this evidence cannot tell you.

Search-based evidence indexes have real limits, and it is worth being explicit about them:

NutriStack

Track what you actually take.

NutriStack is a free iPhone app for organising a supplement routine: what you take, when, and what the published record says about it. Its exploratory interaction checker covers Amiodarone, Ciprofloxacin, and several hundred other substances.

The checker is a research and organisation tool, not a clinical decision aid, and its per-pair assessments are excluded from search until they pass claim-level review.
