Betamethasone acetate
Based on 1 Customer Validation
Betamethasone acetate is a glucocorticoid with prenatal application for preventing respiratory distress syndrome (RDS) in premature infants. Betamethasone acetate exhibits dose-dependent effects on somatic and brain development in offspring when administered prenatally to pregnant rats. Betamethasone acetate can be used for the study of antenatal intervention.

Betamethasone (170-340 μg/ kg, i.n., twice within 4 h on E20) (acetate) induces moderate dose-dependent somatic growth retardation (reduced birth weight, crown-tail length, head diameter) in offspring of pregnant Fisher 344 rats[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
