Background:

Antenatal glucocorticoid therapy is a cornerstone in managing pregnancies complicated by preterm birth risk.
These therapies leverage anti-inflammatory and maturative properties of fluorocorticoids to improve fetal outcomes.

Purpose of the Study:

To provide updated recommendations on the use of antenatal glucocorticoids for pregnancies at risk of preterm delivery.
To highlight the preferred agent and optimal dosing regimen based on current evidence.

Main Methods:

Review of existing clinical guidelines and relevant scientific literature.
Analysis of evidence supporting the efficacy and safety of different glucocorticoids and dosing strategies.

Main Results:

Related Experiment Videos

Antenatal glucocorticoid therapy is strongly recommended for women at risk of delivery before 34 weeks gestation.
Betamethasone is the preferred agent due to its favorable risk-benefit profile compared to dexamethasone.
A maximum of two courses, separated by two weeks, is advised pending further evidence on repeated dosing.

Conclusions:

Antenatal glucocorticoid therapy, particularly with betamethasone, is a highly effective intervention for improving outcomes in preterm birth.
Current recommendations support a specific dosing regimen, with ongoing research into the effects of repeated courses.
