Amiodarone and Digoxin: what the published research says

PubMed indexes 5 records that name Amiodarone and Digoxin 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 Digoxin. 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

5 studies naming Amiodarone and Digoxin.

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

The digoxin-amiodarone interaction.

Cardiovascular drugs and therapy · 1989 · PMID 2487521

Human subjects10 participants

“It has also shown that this interaction is sustained for at least several months. The cause has not been fully elucidated but does not appear to be due to a change in the renal clearance of digoxin.”

Robinson et al. · From the abstract

Names both Amiodarone and Digoxin in its title.

Digoxin-amiodarone interaction

Giornale italiano di cardiologia · 1984 · PMID 6706051

Human subjects39 participants

“The relation between digoxin plasma levels and digoxin bound to erythrocytic membranes--as a marker of the deep tissue accumulation--was not different in patients treated with digoxin or with digoxin + amiodarone, further indicating that amiodarone may not increase digoxin plasma levels by means of a displacement of the glycoside from tissues. The clinical significance of the interaction is still undefined.”

Strocchi et al. · From the abstract

Names both Amiodarone and Digoxin in its title.

The effects of drug-drug interaction on linezolid pharmacokinetics: A systematic review.

European journal of clinical pharmacology · 2024 · PMID 38421436

Systematic ReviewHuman subjects

“This systematic review found that numerous drugs have an impact on the pharmacokinetics of linezolid, and the purported main mechanism may be that linezolid is the substrate of P-glycoprotein. In clinical practice, it is prudent to pay attention to the changes in linezolid pharmacokinetics caused by interactions. Conducting therapeutic drug monitoring (TDM) is beneficial to improve efficacy and reduce adverse reactions of linezolid.”

Xu et al. · Authors' conclusion

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

Itraconazole increases serum digoxin concentration.

Pharmacology & toxicology · 1996 · PMID 8936563

Clinical TrialRandomized Controlled Trial

“Care should be taken if itraconazole is prescribed to patients using digoxin. The mechanism of the itraconazole-digoxin interaction is unclear but may be related to CYP3A4-mediated changes in the pharmacokinetics of digoxin.”

Partanen et al. · From the abstract

Names Amiodarone and Digoxin 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, Digoxin, 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.
