CUROSURF®, is a natural surfactant prepared from porcine lung, containing almost exclusively phospholipids, particularly, phosphatidylcholine (about 70% of the total content in phospholipids and about 1% of specific hydrophobic proteins of low molecular weight: SP-B and SP-C.

PHARMACEUTICAL FORM
Suspension for endotracheobronchial instillation, contained in an unitary dose vial-ampoule for administration by intratracheal or intrabronchial route.

PHARMACOTHERAPEUTIC CLASS
VI-5 Respiratory system, pulmonary tensioactives (surfactants).

THERAPEUTIC INDICATIONS

  • Treatment of respiratory insufficiency syndrome (RIS) in premature newborns with a birth weight of less than 700g.
  • Prophylactic use in premature babies with an estimated gestational age between 24 and 31 weeks with risk of respiratory insufficiency syndrome, or with evidence of surfactant deficiency.

CONTRAINDICATIONS AND SIDE EFFECTS
No contraindications are yet known.

Pulmonary haemorrhage is an event whose incidence increases the more premature is the baby and constitutes a rare and sometimes fatal complication of premature labor.

There is no evidence that supports the increase of the risk of this complication after the administration of CUROSURF®.

No other side effects were reported.

DRUG INTERACTIONS AND OTHER FORMS OF INTERACTION
Not known.

SPECIAL PRECAUTIONS FOR USE
CUROSURF® should only be used in a hospital environment by trained doctors with experience in special cares and reanimation procedures on prematures, mechanic ventilation and monitoring of newborns with RIS.

Babies born after a very prolonged rupture of the membranes (more than 3 weeks), may not show an optimal response to the treatment.

The general state of the baby should be stabilized. It is also recommended to correct acidosis, hypotension, anaemia, hypoglycaemia and hypothermia.

The administration of surfactant is expected to reduce the severity of RIS or the risk of its occurrence, but we cannot expect that it completely eliminates mortality and morbility associated with preterm birth, since premature babies may be exposed to other complications due to their immaturity.

After the administration of CUROSURF®, it has been registered a transient depression of cerebral-electrical activity (with the duration of about 2 to 10 minutes) whose impact is yet unknown.

EFFECTS ON PREGNANT WOMEN, BREAST-FEEDING WOMEN, CHILDREN, ELDERLY PATIENTS AND PATIENTS WITH SPECIAL PATHOLOGIES
Not applicable.

EFFECTS ON THE ABILITY TO DRIVE OR TO USE MACHINES
Not applicable.

LIST OF EXCIPIENTS
Sodium chloride and water for injectable preparations.

USUAL POSOLOGY, WITH REFERENCE TO MAXIMUM DOSE
“Emergency” treatment: The recommended dose is a single dose of 100-200 mg/kg (1.25 – 2.5 ml/kg), body weight.
It is possible the administration of complementary doses of 100 mg/kg in intervals of about 12 hours, in newborns needing assisted ventilation, complemented with oxygen (maximum total dose: 300-400 mg/Kg).

It is advisable to start treatment as soon as possible, after the diagnostic of RIS.
The therapy with CUROSURF started after more than 48 hours after the diagnostic of RIS was not investigated.

Prophylaxis: A single dose of 100-200 mg/Kg as soon as possible (within 15 minutes), after birth.

Complementary doses of 100 mg/kg may be administered 6 to 12 hours after the first dose and, afterwards, in intervals of 12 hours, in case of the occurrence of RIS needing mechanical ventilation (maximum total dose: 300 – 400 mg/kg).

ADMINISTRATION MODE AND ROUTE
Curosurf is available in ready to use vials, which should be stored in the refrigerator between +2ºC and +8ºC.

Before its use, the vial should be warmed up at 37ºC, keeping it in an incubator for about 1 hour or in a water-bath for about three minutes; gently, without agitating, invert the vial one or two times in order to obtain an uniform suspension.
Discard any residues remaining in the vial after the first aspiration.
After warm-up vials should not return to the refrigerator but be discarded instead. The suspension must be taken out of the vial using a syringe connected to a sterile needle and administered by intratracheal or intrabronchial route.

Disconnect the baby from the ventilator for a few moments and administer 1.25 to 2.5 ml/kg of suspension in a single dose bolus, directly in the lower trachea, through the endotracheal tube. Next, the baby should be manually ventilated for about one minute and then connected to the ventilator. Additional doses (1.25 ml/kg) eventually necessary are administered in the same way.

CUROSURF® may also be distributed into the lungs with the help of the ventilator instead of using manual ventilation.

After the administration of CUROSURF®, it is necessary to closely and frequently monitor arterial gases, since it is normally observed an immediate increase of PaO2 or oxygen saturation. However, it is advisable to continuously monitor transcutaneous PO2 or the oxygen saturation, in order to prevent hyperoxia.

Newborns who do not need assisted ventilation should be extubated following the administration of CUROSURF®.

INDICATION OF THE MOST FAVOURABLE MOMENT FOR THE ADMINISTRATION OF THE MEDICINE
According to the doctor’s indication.

DURATION OF THE AVERAGE TREATMENT WHEN IT SHOULD BE LIMITED
The duration of the treatment depends on the clinical situation and its evolution.

INDICATION OF HOW TO DISCONTINUE THE TREATMENT WHEN ITS DISCONTINUATION CAUSES WITHDRAWAL EFFECTS
Not applicable.

MEASURES TO ADOPT IN CASE OF OVERDOSAGE AND/OR INTOXICATION, EMERGENCY SYMPTOMS AND ANTIDOTES
No overdosage cases were reported with the use of CUROSURF®.

However, in the improbable case of accidental overdosage, and only when there is evidence of clinical effects in the baby’s breathing, ventilation or oxygenation, the surplus suspension must be aspirated as much as possible, and the baby treated with support therapy, paying particular attention to the electrolytic balance of the fluids.

ADVICE TO THE PATIENT
Check if the product is within the expiry date mentioned in the package.
Please inform your doctor or pharmacist of the occurrence of any side effects, particularly if they are not mentioned in this leaflet.
Always keep medicines out of reach and sight of children.

SPECIAL PRECAUTIONS FOR STORAGE AND INDICATION OF VISIBLE SIGNS OF DETERIORATION, IF THEY EXIST
The medicine must be stored in the refrigerator 2ºC and 8ºC, protected from light, until its use.
Discard the vial after its use.

DATE OF THE REVISION OF THE LEAFLET : February 2004.
