Hard shell capsule with modified release coating

The invention relates to a method for producing a polymer-coated hard-shell capsule, in which the hard-shell capsule comprises a body and a cap, in which the cap sleeves the body in a pre-locked state or a final locked state in a closed state, wherein the hard shell capsule is provided in a pre-locked state and coated with a coating solution, suspension or dispersion comprising or consisting of: a) at least one polymer; b) at least one flow aid; c) at least one emulsifier; d) optionally, at least one plasticizer; e) optionally, at least one bioactive ingredient; and f) optionally, at least one additive different from a) to e); the coating solution, suspension or dispersion has a surface tension of at most 38 mN/m, in order to obtain a hard shell capsule in a pre-locked state, which is coated, preferably only on the outer surface. Furthermore, the invention relates to polymer-coated hard-shell capsules obtained by the method according to the invention and to the use of said polymer-coated hard-shell capsules f
