Hesperidin and diazepam exhibit synergistic interaction in enhancing sedative and sleep-enhancing effects
The study demonstrates that the natural flavonoid hesperidin, which has sedative and sleep-enhancing properties but does not bind to the benzodiazepine site, synergistically potentiates the effects of diazepam, a GABA(A) receptor agonist. Isobolar analysis confirmed the interaction as synergistic, and pharmacokinetic effects or direct action on the benzodiazepine site were ruled out.

Hesperidin and diazepam exhibit synergistic interaction in enhancing sedative and sleep-enhancing effects The current body of evidence comprises 1 study. EvidenceHub rates the overall confidence at 26/100 (low).
The Claim
Hesperidin and diazepam exhibit synergistic interaction in enhancing sedative and sleep-enhancing effects
This conclusion is most relevant to: Animal subjects (likely rodents, based on typical preclinical sleep research).
What the Research Shows
The conclusion draws on 1 linked study. Highlights from the cited literature:
- ▸Synergistic interaction between hesperidin, a natural flavonoid, and diazepam. (European journal of pharmacology, 2005) —
How It Works
The proposed biological pathway:
- ▸Hesperidin has sedative and sleep-enhancing properties independent of benzodiazepine binding
- ▸Diazepam acts as an agonist at the GABA(A) receptor benzodiazepine binding site
- ▸Combined administration produces synergistic interaction as shown by isobolar analysis
- ▸Result: Enhanced sedative and sleep-enhancing effects beyond additive expectations
Who Might Benefit
Evidence fit by population:
- ▸Animal subjects (likely rodents, based on typical preclinical sleep research)
Recommended Dose
N/A (specific doses not provided in abstract)
Limitations & Caveats
Important context when interpreting this evidence:
- ▸Study conducted in animals, not humans, limiting direct applicability
- ▸Abstract does not report specific sample size, doses, or statistical details for replication
Frequently Asked Questions
What is hesperidin?▼
Hesperidin is a natural flavonoid found in plants like Valeriana, with sedative and sleep-enhancing properties.
Does hesperidin bind to benzodiazepine receptors?▼
No, the abstract states hesperidin is not a ligand for the benzodiazepine binding site on GABA(A) receptors.
What was the main finding of this study?▼
Hesperidin and diazepam showed synergistic interaction in enhancing sedative effects, suggesting potential to reduce diazepam doses.
Was this study done in humans?▼
No, the abstract indicates it was an animal study using the hole board test.
