-At the discretion of the clinician, the endotracheal tube may be suctioned before administering this drug; allow the infant to stabilize before proceeding with dosing.

Administration methods:
-By intratracheal instillation in two divided aliquots through a 5 French end-hole catheter after briefly disconnecting the endotracheal tube from the ventilator.
-By a single aliquot through the secondary lumen of a dual lumen endotracheal tube without interrupting mechanical ventilation.

Reconstitution/preparation techniques:
-Remove the suspension from the refrigerator and slowly warm the vial to room temperature before use.
-Inspect visually for discoloration prior to administration. The suspension should be white to creamy white; discard the vial if the suspension is discolored.
-Gently turn the vial upside-down, in order to obtain a uniform suspension; do not shake.
