Evaluation of peri- and post-natal toxicity of Policosanol in rats
1Department of Toxicology, National Center for Scientific Research, Havana, Cuba.
Insights
Policosanol, a hypocholesterolemic drug, was tested in rats during pregnancy and lactation. It showed no adverse effects on maternal health or offspring development across generations.
Area of Science:
- Pharmacology
- Toxicology
- Developmental Biology
Background:
- Policosanol is a novel hypocholesterolemic agent.
- Investigating its safety during critical developmental periods is crucial.
Purpose of the Study:
- To evaluate the effects of Policosanol on reproductive performance and fetal/neonatal development in Sprague-Dawley rats.
- To assess potential toxic effects in dams and offspring following perinatal and postnatal administration.
Main Methods:
- Oral administration of Policosanol (0, 5, 50, 500 mg/kg/day) to female rats from day 15 of gestation to day 21 postpartum.
- Monitoring of dams (F0) for toxic effects during pregnancy and lactation.
- Examination of offspring (F1 and F2) for postnatal growth, development, behavior, and reproductive capacity.
Main Results:
- No toxic effects were observed in the dams (F0) during the study period.
- No adverse effects on the postnatal growth, behavior, or reproductive ability of the first-generation offspring (F1) were detected.
- Normal physical and sensory development was observed in the second-generation offspring (F2).
Conclusions:
- Policosanol administration during perinatal and postnatal periods does not negatively impact maternal health.
- The compound does not affect fetal or neonatal development, including growth, behavior, and reproductive capacity in offspring.
- Policosanol demonstrates a favorable safety profile concerning reproductive performance and developmental toxicity in Sprague-Dawley rats.
Abstract:
The effects of Policosanol, a newly developmented hypocholesterolemic drug administered during the perinatal and postnatal periods, were studied in Sprague-Dawley rats. This compound was administered orally to female rats at dose levels of 0 (control), 5, 50, and 500 mg/kg/day, from day 15 of pregnancy to day 21 after parturition. The animals were allowed to deliver and their offspring were examined for postnatal growth and development. No signs of toxic effects related to the test material were observed in the dams F0 during pregnancy and lactation. No adverse effects were observed on the postnatal growth, behaviours, or reproductive ability of pups F1. The physical and sensorial development of pups F2 was also normal. These results confirm that Policosanol does not affect the reproductive performance or fetal/neonatal development.
