An apparatus for packaging dosed quantities of solid drug portions, the apparatus comprising: a plurality of storage containers each storing a plurality of solid drug portions and having a dosing means for dispensing first dosed quantities of solid drug portions, a plurality of moving collecting containers for collecting solid drug portions and for outputting the collected drug portions to a packaging station, guiding means for guiding the solid drug portions dispensed by the dosing means to one of the plurality of collecting containers, an ancillary dosing station for delivering second dosed quantities of solid drug portions to the collecting containers, transport means (7, 74, 75) for moving the collecting containers between at least one first location at which the collecting containers receive the solid drug portions from the guiding means, at least one second location at which the collecting containers receive the solid drug portions from the ancillary dosing station, and at least one third location at which the collecting containers output the collected solid drug portions to the packaging station, the collecting containers being moved along a predetermined path, the ancillary dosing station comprising a plurality of buffer receptacles each temporarily holding one solid drug portion or a few solid drug portions and having a delivering means (53, 63) for outputting the held solid drug portion(s) to one of the collecting containers at one of the at least one second location during their movement along the predetermined path, and control means coupled to the transport means and the delivering means (53, 63) of the buffer receptacles for selectively controlling the delivering means (53, 63) depending on the positions of the moving collecting containers so that the solid drug portions temporarily held in the buffer receptacles are output to selected collecting containers. a plurality of storage containers each storing a plurality of solid drug portions and having a dosing means for dispensing first dosed quantities of solid drug portions, a plurality of moving collecting containers for collecting solid drug portions and for outputting the collected drug portions to a packaging station, guiding means for guiding the solid drug portions dispensed by the dosing means to one of the plurality of collecting containers, an ancillary dosing station for delivering second dosed quantities of solid drug portions to the collecting containers, transport means (7, 74, 75) for moving the collecting containers between at least one first location at which the collecting containers receive the solid drug portions from the guiding means, at least one second location at which the collecting containers receive the solid drug portions from the ancillary dosing station, and at least one third location at which the collecting containers output the collected solid drug portions to the packaging station, the collecting containers being moved along a predetermined path, the ancillary dosing station comprising a plurality of buffer receptacles each temporarily holding one solid drug portion or a few solid drug portions and having a delivering means (53, 63) for outputting the held solid drug portion(s) to one of the collecting containers at one of the at least one second location during their movement along the predetermined path, and control means coupled to the transport means and the delivering means (53, 63) of the buffer receptacles for selectively controlling the delivering means (53, 63) depending on the positions of the moving collecting containers so that the solid drug portions temporarily held in the buffer receptacles are output to selected collecting containers.
