Patent number: 12193993Abstract: A process can be used for preparing a polymer coated hard-shell capsule, filled with a fill containing a biologically active ingredient. The hard-shell capsule contains a body and a cap, and in a closed state, the cap overlaps the body in a pre-locked state or a final-locked state. The material of the body and cap contains an ethyl-, methyl-, or propyl-ether of cellulose, starch, or pullulan. The hard-shell capsule is coated with a coating layer, containing one or more anionic cellulose(s), ethyl cellulose, and/or one or more starches comprising at least 35% by weight of amylose, where the coating layer is present in an amount of about 1 to 5.8 mg/cm2. The process involves providing the polymer-coated hard-shell capsule in the pre-locked state to a capsule-filling machine, separating the body and the cap, filling the body with the fill, and rejoining the body and the cap in the final-locked state.Type: GrantFiled: April 30, 2020Date of Patent: January 14, 2025Assignee: Evonik Operations GmbHInventors: Vinay Jain, Ashish Guha, Shraddha Joshi, Felix Hofmann, Bettina Hölzer, Hans Bär
