Beschreibung
Zusammenfassung:	The invention provides novel pellets adapted for biologically active preparations and a novel process for preparing said pellets. The novel pellets are adapted for use in the delivery of a biologically active agent. The pellets have an inner zone comprising a plurality of micropellets which are bound together to form a pellet when the micropellets are dispersed in a matrix of an inert pharmaceutical excipient, a biologically active agent and optionally having an outer zone comprising a surface layer comprising a pharmaceutical excipient with or without a biologically active agent. The pellets will have an arcuate surface due to the manner in which they are formed.
