The emission
performance of a dry-powder inhaler is measured by the amount of
powder or drug delivered, under given conditions.
FlowCaps® operates at the nominal airflow rate of 35 litres
per minute, which is half the flow rate used in most powder inhalers.
It achieves this because of its design efficiency. FlowCaps® is
able to disperse and entrain powder at much lower airflow rates
than competing passive devices.
This allows FlowCaps® to be used by patients where the flow
rate is lower, such as children and elderly patients affected by
chronic obstructive pulmonary disease.
In terms of in-vitro performance, FlowCaps® delivers emitted
doses typically in excess of 85%, and with very high reproducibility. |
