was determined [29:<29 weeks gestation): Endotracheal: 3 mL/kg every 12 hours up to a total of 3 doses. In studies, repeat doses have been administered as frequently as every 6 hours for a total of up to 4 doses if the neonate was still intubated and required at least 30% inspired oxygen to maintain arterial oxygen saturations> 90% or with a PaO 2 80 torr on >30% inspired oxygen (Bloom 2005; Kattwinkel 2000). However, guidelines suggest that dosing intervals more frequent than every 12 hours should not be necessary, unless surfactant is being inactivated by an infectious process, meconium, or blood (AAP [Polin 2014]). Rescue treatment: Newborns: Endotracheal: 3 mL/kg every 12 hours up to a total of 3 doses. In studies, repeat doses have been administered as frequently as every 6 hours for a total of up to 4 doses if the neonate was still intubated and required at least 30% inspired oxygen to maintain arterial oxygen saturations >90% or with a PaO 2 80 torr on >30% inspired oxygen (Bloom 2005; Kattwinkel 2000). However, guidelines suggest that dosing intervals more frequent than every 12 hours should not be necessary, unless surfactant is being inactivated by an infectious process, meconium, or blood (AAP [Polin 2014]). Dosing: Renal Impairment There are no dosage adjustments provided in the manufacturer s labeling. Dosing: Hepatic Impairment There are no dosage adjustments provided in the manufacturer s labeling. Administration Endotracheal tube administration: Gently swirl to redisperse suspension; do not shake; administer dosage divided into 2 aliquots of 1.5 mL/kg each into the endotracheal tube; after each instillation, reposition the infant with either the right or left side dependent; administration is made while ventilation is continued over 20 to 30 breaths for each aliquot, with small bursts timed only during the inspiratory cycles; a pause followed by evaluation of the respiratory status and repositioning should separate the 2 aliquots; calfactant dosage has also been divided into 4 equal aliquots and administered with repositioning in 4 different positions (prone, supine, right and left lateral). Storage Gentle swirling or agitation of the vial of suspension is often necessary for redispersion. Do not shake . Visible flecks of the suspension and foaming under the surface are normal. Calfactant should be stored upright (3 mL vial) and under refrigeration at 2 C to 8 C (36 F to 46 F); protect from light; document date and time removed from refrigeration. Warming before administration is not necessary. Unopened and unused vials of calfactant that have been warmed to room temperature can be returned to refrigeration storage within 24 hours for future use. Repeated warming to room temperature should be avoided. Each single-use vial should be entered only once and the vial with any unused material should be discarded after the initial entry. Drug Interactions Bradycardia-Causing Agents: May enhance the bradycardic effect of other Bradycardia-Causing Agents. Monitor therapy Bretylium: May enhance the bradycardic effect of Bradycardia-Causing Agents. Bretylium may also enhance atrioventricular (AV) blockade in patients receiving AV blocking agents. Monitor therapy Ceritinib: Bradycardia-Causing Agents may enhance the bradycardic effect of Ceritinib. Management: If this combination cannot be avoided, monitor patients for evidence of symptomatic bradycardia, and closely monitor blood pressure and heart rate during therapy. Avoid combination Ivabradine: Bradycardia-Causing Agents may enhance the bradycardic effect of Ivabradine. Monitor therapy Lacosamide: Bradycardia-Causing Agents may enhance the AV-blocking effect of Lacosamide. Monitor therapy Ruxolitinib: May enhance the bradycardic effect of Bradycardia-Causing Agents. Management: Ruxolitinib Canadian product labeling recommends avoiding use with bradycardia-causing agents to the extent possible. Monitor therapy Terlipressin: May enhance the bradycardic effect of Bradycardia-Causing Agents. Monitor therapy Tofacitinib: May enhance the bradycardic effect of Bradycardia-Causing Agents. Monitor therapy Adverse Reactions >10% Cardiovascular: Bradycardia (34%) Gastrointestinal: Endotracheal tube reflux (21%) Respiratory: Cyanosis (65%), airway obstruction (16% to 39%) Warnings/Precautions Concerns related to adverse effects: Transient adverse effects: Transient episodes of bradycardia, decreased oxygen saturation, endotracheal tube blockage or reflux of calfactant into endotracheal tube may occur. Discontinue dosing procedure and initiate measures to alleviate the condition; may reinstitute after the patient is stable. Other warnings/precautions: Administration: For intratracheal administration only. Monitoring: Produces rapid improvements in lung oxygenation and compliance that may require frequent adjustments to oxygen delivery and ventilator settings. Trained personnel: Rapidly affects oxygenation and lung compliance; restrict use to a highly-supervised clinical setting with immediate availability of clinicians experienced in intubation and ventilatory management of premature infants. Monitoring Parameters Continuous heart rate and transcutaneous O 2 saturation should be monitored during administration; frequent ABG sampling is necessary to prevent postdosing hyperoxia and hypocarbia Patient Education Discuss specific use of drug and side effects with caregiver as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?) Have caregiver report immediately to prescriber difficulty breathing, blue or gray skin color, bradycardia, or cough (HCAHPS). Educate caregiver about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Caregiver should consult prescriber for additional questions. Intended Use and Disclaimer: Should not be printed and given to patients. This information is intended to serve as a concise initial reference for healthcare professionals to use when discussing medications with a patient. You must ultimately rely on your own discretion, experience and judgment in diagnosing, treating and advising patients.
