Abstract (en)

[origin: WO9403159A1] A pulse release implant comprising: an axial biodegradable core; a first concentric layer comprising dehydrated hydrogel containing an active ingredient; and an outer coating, said outer coating being removable by the environment in which the implant will reside after administration. A process of preparing a pulse release implant including the steps of: coating an axially disposed biodegradable core material with a hydrogel containing an active ingredient to form a concentric coating; separating the coating into discrete segments disposed along the core material; dehydrating the hydrogel; coating the discrete segments with an outer coating, said outer coating being removable by the environment in which the implant will reside after administration; and removing the exposed core material to obtain the pulse release implants.
