The aim of this prospective, randomized and controlled study was to compare the clinical efficacy of intravenous magnesium sulfate (MgSO 4) and oral sildenafil therapies with persistent pulmonary hypertension of the newborn.A total of 34 infants in the MgSO 4 group and 31 infants in the sildenafil group completed the study. Sildenafil was started with a dose of 1 mg/kg/dose thrice a day and increased to 2 mg/kg/dose after 48 h if partial pressure of oxygen (PO 1] did not increase.
