Abstract
A processing method and apparatus are disclosed for processing an inhaler component of a dry powder inhaler so as to remove any electrostatic charge and improve inhaler performance in drug delivery to the respiratory tract. The method includes exposing the inhaler component, while it contains an amount of medicament, to a gas in a chamber at a first predetermined pressure; exposing the inhaler component, in the chamber, to gas at a second pressure greater than the first pressure; and repeating the exposure of the inhaler component to gas at a pressure no greater than the first predetermined pressure.
