1. A method for filling containers with a composition that comprises or, alternatively, consists of mannitol in powder form, comprising:
a) breaking up a coherent mass of mannitol powder using a centrifugal drum sieve having a mesh gap size in the range of 2.0-5.0 millimeters, so as to obtain a broken-up mass from said coherent mass; and
b) filling a plurality of containers with the broken-up mass of step a)
wherein each container comprises a container compartment that comprises a first volume fraction and a second volume fraction, wherein at the end of step b) the first volume fraction is occupied by a single-dose composition and the second volume fraction is free from said composition, and wherein the first volume fraction is about two-thirds of a total internal volume of the container compartment and the second volume fraction is about one-third of the total internal volume.
