Abstract
The invention relates to processes for dry powder blending. Specifically the invention relates to dry powder blending of pharmaceutical and non-pharmaceutical solid particulate matter and powders. More specifically the invention relates to dry powder blending of microparticles, and to dry powder blends for use as pharmaceuticals. In particular, the present invention relates to a process of preparing a dry microparticulate powder blend comprising one or more micronized active pharmaceutical ingredient(s) (API) and optionally, one or more micronized or non-micronized pharmaceutically acceptable carrier(s) and/or excipient(s), wherein the process comprises the steps of ‘pulsating blending’ of the micronized active pharmaceutical ingredient(s) and the pharmaceutically acceptable carrier(s) and/or excipient(s).
