預防和治療早產兒之呼吸窘迫症(RESPIRATION DISTRESS SYNDROME)。
Beractant 於氣管內給藥後，約 30 分鐘產生作用，作用可持續 48 至 72 小時。因beractant 是直接使用在目標器官¾肺，並於肺泡表面產生生物物理效應，故大部分的劑量在給藥後數小時內會成為肺的一部份，且脂質成分會進入內生性界面活性劑的再利用與再循環過程。本藥大量由肺部代謝；排除半衰期為 20~36 小時。

4. Clinical particulars
4.1 Therapeutic indications
Survanta is indicated for treatment of Respiratory Distress Syndrome (RDS) (hyaline membrane disease) in new born premature infants with a birth weight of 700g or greater and who are intubated and are receiving mechanical ventilation.
Survanta is also indicated for the prophylactic treatment of premature infants <32 weeks gestational age at risk of developing RDS.
4.2 Posology and method of administration
100 mg phosholipid/kg birth weight in a volume not exceeding 4ml/kg.
Treatment: Survanta should be administered early in the course of RDS, i.e. preferably less than 8 hours of age. Depending on clinical course, this dose may be repeated within 48 hours at intervals of at least six hours for up to 4 doses.
Prophylaxis: The first dose of Survanta should be administered as soon as possible after birth, preferably within 15 minutes. Depending on clinical course, this dose may be repeated within 48 hours at intervals of at least six hours for up to 4 doses.
Method of Administration
Survanta should be administered by intratracheal administration (i.e. drug should be conducted into the lungs via an endotracheal tube) using a 5 Fr catheter. The tip of the catheter should lie at the end of the endotracheal tube. Infants should not be intubated solely for the administration of Survanta.
Survanta should be warmed to room temperature before administration (see Precautions).
Before administering Survanta to infants on mechanical ventilation, set the respiratory frequency at 60/minute - with inspiration time 0.5s and Fi02 at 1.0. Inspiratory pressure needs no change at this point.
To ensure distribution of Survanta throughout the lungs, each dose is divided into fractional doses. Each dose can be administered as either two half-doses or four quarter-doses. Each fractional dose is administered with the infant in different positions as given below. Between each position the infant should be ventilated for 30 seconds.
For Four quarter-doses, the recommended positions are :
Right Lateral Position with the head lowered (i.e. head and body slanting down at an angle of approximately 15°).
Left Lateral Position with the head lowered (i.e. head and body slanting down at an angle of approximately 15°).
Right Lateral Position with head elevated (i.e. head and body slanting up at an angle of approximately 15°).
Left Lateral Position with head elevated (i.e. head and body slanting up at an angle of approximately 15°).
For administration of each quarter dose, the ventilator is disconnected, the catheter inserted, the dose administered then the ventilator reconnected. Between each quarter dose the infant is ventilated for 30 seconds.
For two half-doses, the recommended positions are :
• With infant supine, the head and body turned approximately 45° to the right.
• With infant supine, the head and body turned approximately 45° to the left.
When two half-doses of Survanta are being administered there are 2 alternative methods of administration:
Installation with disconnection from the ventilator
Each half dose is administered by disconnecting the endotracheal tube from the ventilator, inserting the catheter and administering the half dose. Between the half doses, the ventilator is reconnected for 30 seconds.
Instillation without disconnection from the ventilator (through a suction port connector).
The first half dose is administered by inserting the catheter through a suction port connector without disconnection from the ventilator. There should be at least 30 seconds between the half doses during which time the catheter is retracted from the endotracheal tube but not removed from the connector. The catheter is then reinserted into the endotracheal tube and the second half dose administered. The catheter is then withdrawn completely.
Dosage in Adults
Dosage in Older People
No specific contraindications for Survanta have been defined by the clinical studies.
4.4 Special warnings and precautions for use
Survanta should only be administered with adequate facilities for ventilation and monitoring of babies with RDS.
Marked improvements in oxygenation may occur within minutes of the administration of Survanta. Therefore, frequent and careful monitoring of systemic oxygenation is essential to avoid hyperoxia. Following Survanta administration, monitoring of the arterial blood gases, the fraction of inspired oxygen and ventilatory change is required to ensure appropriate adjustments.
During the dosing procedure, transient episodes of bradycardia and/or oxygen desaturation have been reported. If these occur, dosing should be stopped and appropriate measures to alleviate the condition should be initiated. After stabilisation, the dosing procedure should be resumed.
4.5 Interaction with other medicinal products and other forms of interaction

Summary of the safety profile
Intracranial haemorrhage has been observed in patients who received either beractant or placebo. The incidence of intracranial haemorrhage in all patients is similar to that reported in the literature in this patient population. Pulmonary haemorrhage has also been reported. Blockage of the endotracheal tube by mucous secretions has been reported. No other serious adverse reactions have been reported.
These are presented in the following table:
The following frequency categories are used: Very common (>1/10); common (>1/100, <1/10); uncommon (>1/1,000, <1/100).

Blockage of endotracheal tube by mucous secretions
No antibody production to Survanta proteins has been observed.
Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme:
If an excessively large dose of Survanta is given, observe the infant for signs of acute airway obstruction. Treatment should be symptomatic and supportive. Rales and moist breath sounds can transiently occur after Survanta is given, and do not indicate overdosage. Endotracheal suction or other remedial action is not required unless clear-cut signs of airway obstruction are present.
5. Pharmacological properties
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Lung Surfactant
ATC Code R07AA02
The mode of action of Survanta is biophysical rather than biochemical, i.e. it reduces surface tension and concomitantly increases lung compliance.
Intratracheally administered Survanta distributes rapidly to the alveolar surfaces and stabilises the alveoli against collapse during respiration thereby increasing alveolar ventilation.
In clinical studies of premature infants with Respiratory Distress Syndrome (RDS), a significant improvement in oxygenation was demonstrated after treatment with a single dose of Survanta.
These infants showed a decreased need for supplemental oxygen and an increase in the arterial/alveolar oxygen ratio (a/Ap02). Significantly decreased need for respiratory support, as indicated by a lower mean airway pressure, was also observed. In most cases these effects were maintained for at least 72 hours after the administration of the single dose of Survanta.
5.2 Pharmacokinetic properties
In preclinical studies using radiolabelled phosphatidylcholine, the clearance rate of Survanta in the lung of three day old rabbits has been shown to be similar to that of natural calf and sheep surfactants (approximately 13% within 24 hours). In addition some re-uptake and secretion of Survanta was shown, implying its entry into a metabolically active surfactant pool.
Since an exogenous preparation of Survanta is delivered directly to the lung, classical clinical pharmocokinetic parameters (blood levels, plasma half-life etc.) have not been studied.
5.3 Preclinical safety data
There are no pre-clinical data of relevance to the prescriber which are additional to that already included in other sections of the SPC.
