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.
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.
A study appearing here is not proof that an interaction exists. Two substances can be named together in a paper that never tested them in combination, and a source listed as background may cover only one of them.
Findings are quoted from each abstract as the authors wrote them. NutriStack has not re-analysed, pooled, or reconciled them, and they may disagree with each other.
NutriStack’s own interaction assessment for this pair is not published here. It has not completed qualified-human clinical review, so it is withheld from search. See the publication gate.
Nothing here is medical advice. Decisions about prescription medication and supplements belong with your prescriber or pharmacist, who can see your full regimen.
The research
5 studies naming Amiodarone and Digoxin.
Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.
Cardiovascular drugs and therapy · 1989 · PMID 2487521

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

Limitations
What this evidence cannot tell you.
Search-based evidence indexes have real limits, and it is worth being explicit about them:
Selection. These records were found by searching PubMed titles and abstracts for both substance names alongside interaction and pharmacokinetic terms. Relevant work that phrases things differently, or is not indexed in PubMed, will be missing.
No effect size. The quoted conclusions are the authors’ words about their own study. We have not extracted effect direction or magnitude, and a single study’s conclusion is not a consensus.
Population mismatch. Findings in healthy volunteers, animals, or a specific patient group may not transfer to you, your dose, or your formulation.
Absence is not safety. Few published studies means the combination is under-studied, which is not the same as established as safe.
