Ibuprofen and Potassium: what the research found

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.

Key findings

What the studies concluded.

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.”

Shirvani et al. · 2017 · Review or meta-analysis · details

“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).”

Vatankhah et al. · 2023 · Human study · details

“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.

Analgesic Efficacy of Ibuprofen and Diclofenac Potassium on Postoperative Endodontic Pain in Maxillary and Mandibular First Molars with Irreversible Pulpitis: A Randomised Controlled Trial.

European endodontic journal · 2023 · PMID 37010198

Randomized Controlled Trial

“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).”

Vatankhah et al. · Authors' conclusion

Names both Ibuprofen and Potassium in its title.

Double-blind comparison of diclofenac potassium, ibuprofen and placebo in the treatment of ankle sprains.

The Journal of international medical research · 1991 · PMID 1864448

Clinical TrialComparative StudyRandomized Controlled Trial60 participants

“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.”

MorĂ¡n · From the abstract

Names both Ibuprofen and Potassium in its title.

Comparative Assessment of Ibuprofen-Arginine and Potassium Nitrate-Fluoride Gels for Reducing Post-Bleaching Dentin Sensitivity: A Randomized, Double-Blind, Split-Mouth Trial.

International journal of dentistry · 2026 · PMID 42339054

“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.”

Colognese et al. · Authors' conclusion

Names both Ibuprofen and Potassium in its title.

Effect of sodium/potassium salt (potash) on the bioavailability of ibuprofen in healthy human volunteers.

European journal of drug metabolism and pharmacokinetics · 2003 · PMID 12877565

Human subjects

“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.”

Yakasai · From the abstract

Names both Ibuprofen and Potassium in its title.

Effect of preoperative oral analgesics on pulpal anesthesia in patients with irreversible pulpitis-a systematic review and meta-analysis.

Clinical oral investigations · 2017 · PMID 27837343

Meta-AnalysisSystematic ReviewHuman subjects

“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.”

Shirvani et al. · Authors' conclusion

Names Ibuprofen and Potassium together in an interaction, co-administration, or pharmacokinetic context.

Randomized, open-label, 5-way crossover study to evaluate the pharmacokinetic/pharmacodynamic interaction between furosemide and the non-steroidal anti-inflammatory drugs diclofenac and ibuprofen in healthy volunteers.

International journal of clinical pharmacology and therapeutics · 2011 · PMID 21781648

Randomized Controlled Trial40 participants

“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.”

Paterson et al. · Authors' conclusion

Names Ibuprofen and Potassium together in an interaction, co-administration, or pharmacokinetic context.
