title: [Efficiency criteria and basic parameters of powder inhalers].
abstract: A high therapeutic efficiency and ecological safety are typical of powder inhalers. However, the designs of devices, serially manufactured in many world countries, are different, which affects their technical parameters. There are also differences pertaining to the definition "efficiency criterion" of a powder inhaler. An attempt is made in the paper to substantiate the efficiency notion of the discussed medical equipment and to analyze the methodological approaches to define such efficiency in the laboratory setting.
