HARD CAPSULE MADE FROM A POLYMER OR COPOLYMER FORMED BY POLYMERIZING AT LEAST ONE POLYMERIZABLE VINYL MONOMER IN THE PRESENCE OF POLYVINYLALCOHOL OR A DERIVATIVE THEREOF

摘要

A hard capsule which is made mainly of a polymer or copolymer obtained by polymerizing or copolymerizing at least one polymerizable vinyl monomer in the presence of polyvinyl alcohol and/or a derivative thereof. Unlike conventional hard capsules, this hard capsule can be filled with a solvent (e.g., polyethylene glycol) for a sparingly soluble drug ingredient.
