Abstract: The invention relates to a homogeneous, non-dried, melt-extruded thermoplastic compound containing 30-60% by weight dry substance of native or chemically modified starch, maximum 11% by weight dry substance of at least one other biopolymer selected from the group consisting of carrageenan or a different polysaccharide or a protein, 20-45% by weight dry substance of at least one softener and a maximum of 20% by weight water. Said compound can be used, advantageously, to produce molded bodies such as soft capsules with increased impact resistance.

Abstract: The present invention relates to a soft capsule, comprising a capsule case and a filling material with at least one pharmacologically or physiologically active substance, characterized in that the capsule case is made by melt extrusion of thermoplastically processable polymer material, and the filling material is solid at under 10° C. and has a dripping point of higher than 55° C.
