The contained module (1) comprises inlets for an active pharmaceutical ingredient (API) and for an excipient. The inlets are in fluid communication with at least one mixing unit (41,46), and the outlet of the tablet press (6) is in fluid communication with the releasable outlet port for tablets. The material stream comprising the API and the excipient is mixed in the mixing units. During operation parameters of the contents of the material stream are measured with one or more analytical sensors upstream of the tablet press. The speed of the tablet press is controlled in response to the parameters measured upstream of the tablet press. The finished tablets are discharged at an outlet of the tablet press (6).
