Abstract

The invention provides a method of making a composition for inhalation which includes the step of mixing particles of additive material having a diameter of not more than 2µm with active particles, wherein the additive material is suitable for promoting the dispersal of active particles upon aerosolisation of a dry powder in a dry powder inhaler.
