| 主权项 | 1. 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 2 μm with active particles, wherein the additive material is suitable for promoting the dispersal of active particles upon aerolisation of a dry powder in a dry powder inhaler, and the step of pressing the particles of additive material to the surfaces of the active particles by a milling step involving compressing the mixture of active and additive particles in a gap of fixed predetermined width, wherein the additive comprises magnesium stearate. | ||
