Abstract: The invention provides pellet for use as a core for a pharmaceutical dosage form having an inner and an outer zone where the inner zone includes a biologically active agent and said outer zone includes a layer formed by applying a substantially dry, free flowing inert powder which forms a non-tacky surface when placed in contact with water. The invention also provides a process for making pharmaceutical pellets where the core or at least one a layer on the core is formed by (a) contacting powder particles, adhering them to each other and compacting the adhered pellets by a rolling movement, wherein the degree of densification is controlled by the rolling movement; and (b) feeding a sufficient amount of a substantially dry, free flowing inert powder which forms a non-tacky surface when placed in contact with water to provide on said particles an outer zone including a layer formed from said substantially dry, free flowing inert powder.

Abstract: A method of coating spherical particles of a beta blocker compound which is based on (a) determining the surface area of a weighed sample of said spherical particles; (b) determining the weight of coating material per surface area unit of spherical particles that will provide a desired release profile for said beta-blocker; (c) determining the surface area of a subsequent batch of spherical particles containing the same beta; (d) coating the subsequent batch of spherical particles with the coating applied in step (b) to provide a coating having substantially the same weight of coating material per surface area unit of spherical particles as determined in step (b).

Abstract: The invention proves a novel compressed tablet of a pharmaceutical compound and a method of making a tablet of a pharmaceutical compound which are based on uncoated pellets containing a pharmaceutical compound that are dispersed in a matrix which comprises said pellets and a swellable polymer which is compressed into a tablet that is coated with an enteric polymer.
