Test of nebulizers

Nebulizer testing

The pharmacopeial assessment of Nebulizers are described in 2.9.44 and in USP <1601>. The delivered dose from an Nebulizer is tested by using a lung simulator that are generating a tidal inhale/exhale breathing pattern through the device. To slow down the evaporation of the nebulized droplets in the impactor, the cascade (APSD) testing is performed used cooled impactors.
