Summary
Hyperoside exposure during gestation impacted fetal rat development, causing reduced body weight and length in high-dose groups. Pregnant women should use hyperoside cautiously due to potential effects on embryo-fetal development.
Area of Science:
- Pharmacology
- Developmental Toxicology
- Teratology
Context:
- Hyperoside is a flavonoid with potential therapeutic uses.
- Assessing the safety of medications during pregnancy is crucial.
- Embryo-fetal development is sensitive to exogenous substances.
Purpose:
- To evaluate the toxicity of hyperoside on rat embryo-fetal development.
- To inform safe drug usage recommendations during gestation.
Summary:
- Pregnant rats received varying doses of hyperoside (30, 175, 1000 mg/kg/day) or controls (cyclophosphamide, vehicle) during critical developmental periods (gestation days 6-15).
- Maternal parameters and fetal outcomes, including malformations, were assessed on gestation day 20.
- While no gross maternal abnormalities were observed, high-dose hyperoside significantly reduced fetal body weight, embryo length, and tail length compared to controls.
Impact:
- Findings suggest hyperoside may pose risks to fetal development at higher doses.
- Results indicate a need for caution when prescribing hyperoside to pregnant individuals.
- This study contributes to understanding the developmental toxicity of flavonoids.

01:07Teratogenicity
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
01:23Toxicity Testing in Animals
Toxicity tests in animals are grounded on two main assumptions: first, the effects observed in laboratory animals can be extrapolated to humans, especially when adjusted for body surface area; second, high-dose exposure in animals is essential to identify potential human hazards from lower doses. This is based on the quantal dose-response concept, which faces the challenge of extrapolating results from relatively few test animals to much larger human populations. For example, a 0.01% incidence...
