IMPROVEMENTS IN OR RELATING TO FORMULATIONS FOR USE IN INHALER DEVICES

摘要

A formulation for an inhaler device comprises carrier particles having a diameter of at least 50 mu m and a mass median diameter of at least 175 mu m; active particles; and additive material to which is able to promote release of the active particles from the carrier particles on actuation of the inhaler device. The formulation has excellent flowability even at relatively high fine particle contents.
