Candesartan and Potassium: what the published research says

PubMed indexes 7 records that name Candesartan 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 Candesartan 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

7 studies naming Candesartan and Potassium.

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

Serum concentration of potassium in chronic heart failure patients administered spironolactone plus furosemide and either enalapril maleate, losartan potassium or candesartan cilexetil.

Journal of clinical pharmacy and therapeutics · 2005 · PMID 16336294

Clinical Trial

“The occurrence of hyperkalemia in patients administered spironolactone is influenced by the dose, but when it is used concomitantly with enalapril, losartan or candesartan, the occurrence of hyperkalemia exceeding 5.5 mEq/L may increase even if the dose of spironolactone is as low as 25 mg. Thus it is essential to always monitor serum potassium.”

Saito et al. · Authors' conclusion

Names both Candesartan and Potassium in its title.

Inhibitory effects of candesartan on KCa3.1 potassium channel expression and cell culture and proliferation in peripheral blood CD4(+)T lymphocytes in Kazakh patients with hypertension from the Xinjiang region.

Clinical and experimental hypertension (New York, N.Y. : 1993) · 2018 · PMID 29388859

Human subjects

“Increase in functional KCa3.1 channels expressed in CD4+ T lymphocytes of Kazakh patients with hypertension was blocked by candesartan, providing theoretical support for hypertension treatment at the cellular ion channel level. Candesartan may potentially regulate hypertensive inflammatory responses by inhibiting T-lymphocytic proliferation and KCa3.1 potassium channel expression in CD4 + T lymphocytes.”

Li et al. · Authors' conclusion

Names both Candesartan and Potassium in its title.

Carvedilol accelerate elevation of serum potassium in chronic heart failure patients administered spironolactone plus furosemide and either enalapril maleate or candesartan cilexetil.

Journal of clinical pharmacy and therapeutics · 2006 · PMID 17176359

Human subjects

“When carvedilol is used concomitantly with spironolactone, furosemide and enalapril or candesartan, it is necessary to monitor serum potassium concentration, even if spironolactone is administered at a low dose of 25 mg/day.”

Saito et al. · Authors' conclusion

Names both Candesartan and Potassium in its title.

Direct effects of candesartan and eprosartan on human cloned potassium channels involved in cardiac repolarization.

Molecular pharmacology · 2001 · PMID 11259627

Human subjects

“Eprosartan prolonged the action potential duration in muscles driven at 0.1 to 1 Hz, but it shortened this parameter at faster rates (2--3 Hz). All these results demonstrated that candesartan and eprosartan exert direct effects on Kv1.5, HERG, KvLQT1+minK, and Kv4.3 currents involved in human cardiac repolarization.”

Caballero et al. · From the abstract

Names both Candesartan and Potassium in its title.

Interactions between levetiracetam and cardiovascular drugs against electroconvulsions in mice.

Pharmacological reports : PR · 2014 · PMID 25443741

Comparative StudyAnimal study

“Although experimental data can be hardly extrapolated to clinical practice, it is suggested that perindopril arginine may positively influence the anticonvulsant action of LEV in epileptic patients. The use of losartan potassium, candesartan cilexetil, captopril, hydrochlorothiazide or ethacrynic acid in patients treated with LEV seems neutral regarding its anticonvulsant activity.”

Lukawski et al. · Authors' conclusion

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

Phase I trial of gemcitabine and candesartan combination therapy in normotensive patients with advanced pancreatic cancer: GECA1.

Cancer science · 2012 · PMID 22515232

Clinical Trial, Phase I14 participants

“Candesartan 16 mg is the recommended dose in combination with gemcitabine in the treatment of advanced pancreatic cancer. (UMIN CTR: UMIN000002152).”

Nakai et al. · From the abstract

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

Long-term antiproteinuric effect of dual renin-angiotensin system blockade.

Cardiovascular therapeutics · 2009 · PMID 19426247

Clinical Trial28 participants

“The antiproteinuric effect of dual renin-angiotensin system blockade combining candesartan and ACE inhibitors remain after 36 months without losing its initial effect. Blood pressure changes seem not to explain this long-term antiproteinuric effect.”

Robles et al. · From the abstract

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

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 Candesartan, 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.
