Infants born too early can get a lung disease called Bronchopulmonary dysplasia (BPD). Infants with BPD are likely to have pulmonary hypertension, a condition where the blood vessels in the lungs get blocked or destroyed, causing high blood pressure. Pulmonary hypertension increases the risk of death from BPD. There are no medicines approved by the U.S. Food and Drug Administration (FDA) for treating BPD. However, doctors often use the medicine sildenafil to manage high blood pressure in infants with BPD.
