Simvastatin induces dose-dependent sleep-wake disruption in Drosophila melanogaster, with 0.5 mM causing insomnia-like phenotype and 1.0 mM increasing arousal
Simvastatin at 0.5 mM produced an insomnia-like phenotype with reduced total sleep and prolonged sleep latency, while 1.0 mM increased wake activity and delayed sleep onset without reducing total sleep. No effect was observed at 0.05 mM.

Simvastatin induces dose-dependent sleep-wake disruption in Drosophila melanogaster, with 0.5 mM causing insomnia-like phenotype and 1.0 mM increasing arousal The current body of evidence comprises 1 study. EvidenceHub rates the overall confidence at 24/100 (low).
The Claim
Simvastatin induces dose-dependent sleep-wake disruption in Drosophila melanogaster, with 0.5 mM causing insomnia-like phenotype and 1.0 mM increasing arousal
This conclusion is most relevant to: Wild-type Drosophila melanogaster (fruit flies).
What the Research Shows
The conclusion draws on 1 linked study. Highlights from the cited literature:
- ▸Simvastatin modulates sleep-wake behavior and locomotor activity in a dose-dependent manner in Drosophila. (Frontiers in pharmacology, 2026) —
How It Works
The proposed biological pathway:
- ▸Simvastatin exposure at varying doses
- ▸Disruption of sleep architecture
- ▸Dose-dependent modulation of sleep initiation and maintenance
- ▸Result: insomnia-like phenotype at 0.5 mM, increased arousal at 1.0 mM
Who Might Benefit
Evidence fit by population:
- ▸Wild-type Drosophila melanogaster (fruit flies)
Recommended Dose
N/A
Limitations & Caveats
Important context when interpreting this evidence:
- ▸Study conducted in Drosophila, not directly translatable to humans
- ▸Only acute effects reported; chronic exposure not assessed
- ▸Mechanistic pathways underlying dose-dependent effects not elucidated
Frequently Asked Questions
Does simvastatin affect sleep in all doses?▼
No, effects were dose-dependent: 0.05 mM had no effect, 0.5 mM caused insomnia-like symptoms, and 1.0 mM increased arousal without reducing total sleep.
What is the relevance of Drosophila for studying statin effects on sleep?▼
Sleep regulation in Drosophila is conserved with mammals, making it a useful model for investigating drug-induced behavioral changes, though further validation is needed.
Could simvastatin cause insomnia in humans based on this study?▼
This study suggests potential sleep-disrupting effects at certain doses in flies, but human studies are required to confirm any clinical relevance.
What concentrations of simvastatin were tested?▼
Concentrations of 0.00 (control), 0.05, 0.5, and 1.0 mM were tested in the fly food.
