Pravastatin and Quercetin: what the published research says

PubMed indexes 2 records that name Pravastatin and Quercetin 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 Pravastatin and Quercetin. 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 Pravastatin and Quercetin.

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

The comparison in vitro the effects of pravastatin and quercetin on the selected structural parameters of membrane erythrocytes from patients with hypercholesterolemia

Polski merkuriusz lekarski : organ Polskiego Towarzystwa Lekarskiego · 2007 · PMID 17598654

Comparative StudyHuman subjects

“1. Pravastatin and quercetin, in vitro, in similar degree decrease the level of membrane cholesterol and advantageously influence on membrane fluidity of erythrocytes from patients with hypercholesterolemia type II. 2. Pravastatin, in vitro, in opposite to quercetin doesn't influence on lipid peroxidation in erythrocytes of patients with hypercholesterolemia type II and healthy.”

Broncel et al. · Authors' conclusion

Names both Pravastatin and Quercetin in its title.

Inhibition of the organic anion-transporting polypeptide 1B1 by quercetin: an in vitro and in vivo assessment.

British journal of clinical pharmacology · 2012 · PMID 22114872

Randomized Controlled Trial

“These findings suggest that quercetin inhibits the OATP1B1-mediated transport of E3S and pravastatin in vitro and also has a modest inhibitory influence on the pharmacokinetics of pravastatin in healthy Chinese-Han male volunteers. The effects of quercetin on other OATP1B1 substrate drugs deserve further investigation.”

Wu et al. · Authors' conclusion

Names Pravastatin and Quercetin 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 Pravastatin, Quercetin, 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.
