Potassium and Ziprasidone: what the published research says

PubMed indexes 2 records that name Potassium and Ziprasidone 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 Potassium and Ziprasidone. 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

2 studies naming Potassium and Ziprasidone.

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

Additive effects of ziprasidone and D,L-sotalol on the action potential in rabbit Purkinje fibres and on the hERG potassium current.

Journal of pharmacological and toxicological methods · 2005 · PMID 15922632

Human subjects

“The present study demonstrates that ziprasidone induces an AP prolongation due to its propensity to block the hERG channel. Moreover, ziprasidone and d,l-sotalol, superfused concomitantly exhibit additive effects on the AP duration since they do not interact as competitors for the hERG channel.”

Ducroq et al. · Authors' conclusion

Names both Potassium and Ziprasidone in its title.

Validation and Clinical Utility of the hERG IC50:C(max) Ratio to Determine the Risk of Drug-Induced Torsades de Pointes: A Meta-Analysis.

Pharmacotherapy · 2018 · PMID 29380488

Meta-AnalysisValidation StudyHuman subjects

“The hERG IC50:Cmax ratio was correlated with TdP incidence for culprit drugs. This validation provides support for the potential use of the hERG IC50:Cmax ratio for clinical decision making in instances of drug selection where TdP risk is a concern.”

Lehmann et al. · Authors' conclusion

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

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 Potassium, Ziprasidone, 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.
