    摘要: A process for preparing a polymer-coated hard shell capsule can be performed. The hard shell capsule has a body and a cap. In the closed state the cap overlaps the body either in a pre-locked state or in a final-locked state. The hard shell capsule is provided in the pre-locked state and coated with a coating solution, suspension or dispersion that has at least one polymer; at least one glidant; at least one emulsifier; optionally at least one plasticizer; optionally at least one biologically active ingredient; and optionally at least one additive, different from the above. The process is used to obtain a coated, preferably only at the outer surface, hard shell capsule in the pre-locked state, wherein the coating solution, suspension or dispersion has a surface tension of at most 38 mN/m. The polymer-coated hard shell capsule obtained from the process is used for immediate, delayed or sustained release.

    摘要: A method for preparing a plant-based hard capsule for rapid disintegration, the method comprises: weighing a coagulant aid, dissolving in distilled water at 75-90° C., and stirring to obtain a first solution; maintaining a temperature of the first solution at 75-90° C., adding a gel-forming agent, and stirring; adding a film-forming agent with a weight percentage of 5%-25%, stirring, finally adding a plasticizer by a weight percentage of 0-3%, and stirring until the film-forming agent and the plasticizer are completely dissolved to obtain a material solution; leaving the material solution to stand at 45-60° C. to obtain a gel solution; and cooling the gel solution to 40-50° C., dipping the gel solution for forming, and drying for 100-200 minutes under a condition of 20-35° C. and a 40%-60% relative humidity; and demoulding, cutting, and combining together by sleeving to obtain the plant-based hard capsule for the rapid disintegration.
