The present invention relates to a kinetic implant comprising(a) biodegradable material comprising opened starch, destructurized starch or a mixture of opened starch and destructurized starch, (b) a biologically or pharmaceutically active substance; and (c) a stabilizing component stabilizing the biologically or pharmaceutically active substance. The biodegradable material comprises about 50 to about 100 wt. % of opened starch, destructurized starch or a mixture of opened starch, based on the total weight of the biodegradable material, the biodegradable material having a bulk density of 1.0 to 1.5 kg/dm3. The kinetic implant has a length :diameter ratio of more than 4, provided that the length of the kinetic implant is between 1 mm to 50 mm. The kinetic implant has a weight such that it can be provided with an amount of kinetic energy in the range of 0.1 to 10 J.
