Delivered dose (DD) and emitted dose (ED) testing

The total dose that is exiting the device and entering the patient’s mouth is referred to as the delivered dose (DD) or emitted dose (ED). Often these tests are combined with the impactor tests and measured through inhaler lifetime (beginning, middle, and end), which is a requirement from regulatory authorities. The testing procedure is described in European Pharmacopeia 2.9.18 and in US Pharmacopeia <601>.

At Emmace we can provide delivered or emitted dose analyses performed according to the Pharmacopeias, or we can use more time efficient methods developed internally.

Emmace provides these dose measurements on dry powder inhalers, metered dose inhalers, nebulizers and nasal devices.
