Characteristics of the Novolizer® dry powder inhaler

The Novolizer®…

Novolizer®

  • is a dry powder inhaler with multiple feedback mechanism to reassure the patient that the inhalation was carried out correctly.
  • is equipped with a dosage stop system releasing the following dose only after the previous dose has been inhaled correctly.
  • has a dose counter which moves after successful inhalation and provides so complance measurement.
  • is avoiding underdosing
  • has a low-to-medium intrinsic resistance. An inspiratory flow rate of at least 35 l/min is necessary to overcome the trigger threshold. However it has been demonstrated that even children aged 4 to 5 years achieved higher peak inspiratory flow rates than required (in average 60 l/min).
  • During an inhalation manoeuvre about 90% of the metered dose is delivered at the mouthpiece with only little variability.

Compared with other devices the Novolizer® has unique features not present in any other DPI.

Drugs approved for use with the Novolizer® include budesonide (Novopulmon®, Budecort®), formoterol (Formatris®, Formotop®), and salbutamol (Ventilastin®, Salbu®).
