Diclofenac and Potassium: what the published research says

PubMed indexes 8 records that name Diclofenac and Potassium 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 Diclofenac and Potassium. 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

8 studies naming Diclofenac and Potassium.

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

Bioavailability of diclofenac potassium at low doses.

British journal of clinical pharmacology · 2005 · PMID 15606444

Clinical TrialRandomized Controlled Trial10 participants

“Our data indicate that diclofenac-K is rapidly and well absorbed at low dose, and are consistent with a rapid onset of action of the drug. Abbreviations AUC, area under plasma concentration-time curve; C(max), peak plasma concentration; CI, confidence interval; COX, cyclooxygenase; D, dose; F, absolute bioavailability; t(max), time to reach C(max).”

Hinz et al. · Authors' conclusion

Names both Diclofenac and Potassium in its title.

Diclofenac potassium for oral solution (CAMBIA(®)) in the acute management of a migraine attack: clinical evidence and practical experience.

Therapeutic advances in neurological disorders · 2017 · PMID 28507605

Review

“Diclofenac oral solution may offer rapid and sustained pain relief for patients who do not achieve pain resolution with other medications. In addition, patients who experience central sensitization with allodynia may benefit from the cyclooxygenase-blocking activity of diclofenac, which is needed in this advanced phase of migraine.”

Joshi et al. · From the abstract

Names both Diclofenac and Potassium in its title.

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 Diclofenac, Potassium, 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.
