PubMed indexes 8 records that name Ibuprofen and Potassium together, either in the title or in an interaction, co-administration, or pharmacokinetic context. The key findings come first, in the authors’ own words, followed by every study with its design and PubMed link.
A summary of published research, not medical advice. A pharmacist can check any combination against your full list of medicines and supplements.
Reviews and human studies first. Each quote is the authors’ own conclusion about their study, not a NutriStack assessment, and a single study is not a consensus.
“The administration of preemptive analgesics can induce superior intraoperative analgesia for patients with irreversible pulpitis. However, strategies such as co-administration of certain types of analgesics and anesthetic solution might be predictors of treatment effect. Additionally, there was no association between different timing and dosage of analgesics and treatment effect.”
“Based on the results, taking multi-dose DFK 50 mg by the clock had better analgesic outcomes than multi-dose IBU 400 mg for PEP management. (EEJ-2022-01-07).”
“Conclusions: Diclofenac potassium was more effective than paracetamol or ibuprofen for reducing postoperative pain associated with tooth extraction and deep cavity preparation. Patients' distress levels can be alleviated by using preemptive analgesics.”
The research
8 studies naming Ibuprofen and Potassium.
Strongest relevance first: papers naming both substances in the title, then human trials and systematic reviews.

“No serious adverse effects were reported. In conclusion, diclofenac potassium has been demonstrated to be effective in the treatment of acute ankle sprains and it had a rapid onset of action and good tolerability.”

“Ibuprofen-arginine gel and potassium nitrate with sodium fluoride proved equally effective in managing post-bleaching dentin hypersensitivity without compromising esthetic outcomes. The combination of ibuprofen and arginine represents a safe, cost-effective, and efficient alternative, offering clinical benefits and expanding therapeutic options for dental practitioners in daily practice.”

“The Kel for hydroxy-ibuprofen increased from 0.71 +/- 0.94 hr(-1) to 0.81 +/- 0.21 hr(-1) (p<0.05) respectively. The study has indicated that sodium/potassium salt extract significantly decreased the bioavailability of ibuprofen.”

“Pharmacodynamic effects were seen with oral diclofenac (urine output) and ibuprofen (urine sodium excretion). Furosemide also affected plasma and urine pharmacokinetic profiles. Pharmacologic effects of DETP on furosemide were not observed under these conditions. Additional research is warranted to delineate the potential interactions of other NSAIDs with furosemide and other loop diuretics.”

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.
How to read this page
A literature summary, not guidance.
A study listed here is not proof that Ibuprofen and Potassium interact. 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.
Decisions about prescription medication and supplements belong with your prescriber or pharmacist, who can see your full regimen. Our timing guide and forms guide explain the general mechanisms.
