What dosage form does VasoKINOX come in?

What does VasoKINOX contain?

The active substance is nitric oxide, its dosage is 450 ppm mole/mole. The other ingredient is nitrogen. Nitrogen is a major component of the air we breathe.

What is VasoKINOX used for?

VasoKINOX is a gas mixture, composed of nitric oxide and nitrogen, used to treat acute pulmonary hypertension (increase in blood pressure in the pulmonary circulation), which can occur during heart surgery.

VasoKINOX is a ‘PRESCRIPTION ONLY MEDICINE’. It is to be given only to the person for whom it has been prescribed.

How VasoKINOX works?

VasoKINOX can improve the flow of blood through the lungs by relaxing the cells in the blood vessels and allowing the blood vessels to widen. This may help to decrease the blood pressure and increase the amount of oxygen that reaches the blood.

When VasoKINOX should not be used

Do not use VasoKINOX if:

  • you are allergic to nitric oxide or nitrogen
  • in newborns who have the following heart defects:
    – right-to-left shunt
    – malignant left-right arterial canal

VasoKINOX should not be used in premature infants born before 34 weeks from conception.

Tell your doctor if you are pregnant or breast feeding. VasoKINOX should not be used during pregnancy. The effect of VasoKINOX in pregnant woman is unknown.

It is not known if VasoKINOX is excreted in breast milk. Talk to your doctor, who will help you to decide if breast feeding should be stopped or VasoKINOX should be stopped.

How to use VasoKINOX

VasoKINOX is a medical gas only administered in hospitals by healthcare professionals.

Your doctor will determine the appropriate dose of VasoKINOX as well as the length of treatment, depending on your condition and age.

VasoKINOX is administered by inhalation, by mechanical ventilation after dilution in an air/oxygen mixture for patients in Intensive Care Units under respiratory assistance and also in the operating room.

On contact with oxygen, nitric oxide can be converted into nitrogen dioxide, which is an irritant for the bronchial tubes. This is why, throughout administration, the concentrations of inhaled nitric oxide and nitrogen dioxide are continuously measured. In certain clinical circumstances, administration of nitric oxide by ventilation through a mask is possible for a very short duration (5 to 10 mn).

VasoKINOX treatment should not be stopped abruptly.

If you take too much (overdose)

As VasoKINOX will be given under the supervision of your doctor it is unlikely that you will receive too much.

Your doctor will take the appropriate measures if too much VasoKINOX is received.

Discontinuation of VasoKINOX treatment:

At the end of the treatment in intensive care, the doctor will gradually reduce the dose of VasoKINOX administered (withdrawal stage), by monitoring the change in your condition.

In fact, a sudden halt in the treatment after several hours of administration may result in the deterioration of your clinical status: this is called the “rebound effect”.

If you have other questions on the use of this medicine, ask your doctor for more information.

Before you are given VasoKINOX

Other things to be aware of before being treated with VasoKINOX include:

Patients with abnormal heart function:
In patients whose hearts are less efficient than normal at pumping blood around the body, nitric oxide can increase the chance of serious side effects occurring, such as the build up of fluid in the lungs, worsening of abnormal heart function, low blood pressure, abnormally slow heart beat, and stopping of the heart.

Using other medicines:
Tell your doctor if you are taking, have recently taken any other medicines.

The doctor will decide whether it is necessary to treat you with VasoKINOX and with other medicines at the same time.

VasoKINOX must be administered with caution if the following medicines are taken at the same time:

  • Medicines called ‘nitric oxide donors’- such as drugs containing sodium nitroprusside and nitroglycerine. Their effect can add to the effect of VasoKINOX
  • Methaemoglobin-generating drugs – such as drugs containing alkylated nitrates and sulphamides, prilocaine. These can increase the blood concentration of methaemoglobin
  • Medicines which widen your blood vessels such as prostacyclin and its analogues

Side effects

Like all medicines, VasoKINOX can cause side effects, although not everybody gets them.

Side effects that are very commonly seen (affects more than 1 user in 10) in association with VasoKINOX therapy include:

  • Low level of blood platelets.

Side effects that are commonly seen (affects more than 1 user in 100) in association with VasoKINOX therapy include:

  • Low blood pressure, airless or collapsed lung.

Side effects that may be seen, but uncommonly (affects between 1 user in 100 and 1 user in 1000) are:

  • Increased amount of methaemoglobin (a form of haemoglobin unable to carry oxygen) that reduces the release of oxygen to body tissues.

These side effects may happen when VasoKINOX is stopped suddenly:

  • Bradycardia (low heart beat )
  • Hypoxemia (too low amount of oxygen in the blood)

These side effects may happen if you are accidentally exposed to VasoKINOX:

  • Headache,
  • dizziness,
  • dry throat
  • shortness of breath

You should directly inform the personnel if you experience headache while being in close proximity to your child or a patient receiving VasoKINOX.

If any of the side effects becomes serious, or if you notice any side effects not listed in this leaflet, please tell your doctor.
