Abstract
A powder for use in a dry powder inhaler includes active particles and carrier particles for carrying the active particles. The powder further includes additive material on the surfaces of the carrier particles to promote the release of the active particles from the carrier particles on actuation of the inhaler. The powder is such that the active particles are not liable to be released from the carrier particles before actuation of the inhaler. The inclusion of additive material in the powder has been found to give an increased respirable fraction of the active material.
