ABSTRACT:
A method of treating pulmonary hypoplasia in infants has been developed, wherein epidermal growth factor (EGF) is administered to the pulmonary system of an infant in need of treatment thereof. The EGF is administered as an aerosol or dry powder directly to the pulmonary tree, or into the amniotic fluid before birth if a situation such as oligohydramnios is recognized pre-term. The method can also be used to treat persistent pulmonary hypertension of the newborn. A hydrophobic angiotensin I-converting enzyme (ACE) inhibitor such as ramipril can also be used for the oral treatment of persistent pulmonary hypertension of the newborn.
