In many cases, pregnant women are advised by doctors to inject drugs to mature the fetus' lungs to prevent the risk of respiratory failure if there is a premature birth, reduce the rate of neonatal mortality and other diseases.

Every pregnant woman wants her baby to be born with the most fully developed and healthy body. However, in cases of premature birth, the baby may have respiratory problems due to the lungs not being fully developed. To stimulate early lung maturity in cases of premature birth, the doctor may advise the pregnant mother's family to inject fetal lung stimulants.

Pregnant women at risk of premature birth or threatened premature birth are often prescribed lung maturation injections by doctors. So what is the effect of lung maturation drugs on the fetus and when should pregnant women get the injection to maximize the drug's effect?

Currently, the two most commonly used lung maturation drugs for fetuses are Dexamethasone and Betamethasone. Lung maturation injections will help promote and support the completion of lung respiratory function, in cases where the fetus may have to be born earlier than expected.
