Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Diuretics and fluid restriction are considered a mainstay of therapy in the management of BPD to combat interstitial alveolar edema. Short courses of furosemide followed by long-term therapy using a thiazide diuretic with concurrent spironolactone have shown improvement in pulmonary function and better outcomes. Double-blinded, randomized, placebo-controlled trials have shown improvement in pulmonary compliance, airway resistance, infants alive at discharge, and a decrease in fraction of inspired oxygen and need for furosemide boluses.
Spironolactone is a competitive aldosterone receptor antagonist that acts on the distal convoluted tubule and collecting duct to facilitate sodium excretion while conserving potassium and hydrogen ions. Since only a minimal amount of sodium filtered by the glomerulus reaches the distal tubule, spironolactone is considered a weak diuretic. Spironolactone is primarily used with chlorothiazide for its potassium-sparing effect to reduce the need for electrolyte supplementation. There has only been one prospective, randomized, double-blind, placebo-controlled study comparing chlorothiazide with or without the addition of spironolactone in premature infants with chronic lung disease. This study demonstrated no difference between the groups in the need for electrolyte supplementation, electrolyte balance, or pulmonary function. In addition, preterm infants' distal tubules may respond inadequately to aldosterone; thereby, limiting the role of spironolactone in this patient population.
In the neonatal population, spironolactone is primarily used in addition with chlorothiazide for its potassium-sparing effects to reduce the need for electrolyte supplementation. However, evidence and current practice suggests the majority of patients still receive electrolyte supplementation. One study evaluated spironolactone's effect on the need for electrolyte supplementation, but there is no published data with a primary outcome evaluating spironolactone's effect on the quantity of electrolyte supplementation. We hypothesize there will be no difference in the amount of electrolyte supplementation between the two groups.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Spironolactone
Oral spironolactone suspension dosed at 3 mg/kg/day will be administered once-daily to the patients assigned to the treatment arm.
Spironolactone
Patients will continue to receive standard of care as if they were not enrolled in the study. All patients will receive oral chlorothiazide 40 mg/kg/day divided twice-daily, electrolyte supplementation as needed based on a standard algorithm, and if needed, rescue enteral furosemide 2 mg/kg/day. The intervention will be enteral spironolactone 3 mg/kg once daily
Placebo suspension
An oral placebo suspension dosed at 3 mg/kg/day administered once-daily will be given to patients in the placebo arm.
Placebo
Patients will continue to receive standard of care as if they were not enrolled in the study. All patients will receive oral chlorothiazide 40 mg/kg/day divided twice-daily, electrolyte supplementation as needed based on a standard algorithm, and if needed, rescue enteral furosemide 2 mg/kg/day.
