Hydrochlorothiazide and L-Arginine: what the published research says

PubMed indexes 5 records that name Hydrochlorothiazide and L-Arginine 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 Hydrochlorothiazide and L-Arginine. 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

5 studies naming Hydrochlorothiazide and L-Arginine.

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

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 Hydrochlorothiazide and L-Arginine together in an interaction, co-administration, or pharmacokinetic context.

Vascular effects of nebivolol added to hydrochlorothiazide in African Americans with hypertension and echocardiographic evidence of diastolic dysfunction: the NASAA study.

Journal of cardiovascular pharmacology and therapeutics · 2012 · PMID 22388001

Controlled Clinical Trial

“Reduced BP with nebivolol in hypertensive African Americans and echocardiographic evidence of diastolic dysfunction correlates with improved endothelial function. Furthermore, improvement in endothelial function and increased nitric oxide bioavailability suggests a potential mechanism of efficacy of nebivolol in these patients.”

Khan et al. · Authors' conclusion

Names Hydrochlorothiazide and L-Arginine 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 Hydrochlorothiazide, L-Arginine, 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.
