Abstract

The invention belongs to the field of pharmaceutical preparations, and discloses a calcium polycarbophil tablet easy to rapidly and completely disintegrate. The tablet is prepared by directly tabletting an air jet pulverization co-treatment substance of mixed powder of polycarbophil calcium and mannitol, a filling agent, a disintegrating agent / gas production disintegrating agent, a flow aid and a lubricating agent. According to the invention, the particle size of calcium polycarbophil is reduced, the tablet is completely disintegrated by virtue of combined application of a common disintegrating agent and a gas-producing disintegrating agent, excellent water solubility and non-hygroscopicity of mannitol and a direct tabletting process, calcium ions in a 0.1 mol / L HCl solution are fully removed, and the disintegration effect under an accelerated condition is obviously superior to that of a commercially available preparation. Meanwhile, the preparation is simple in process, free of solvent addition, good in stability and process reproducibility and suitable for large-scale production.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical preparations, and in particular relates to a calcium polycarbophil tablet that is easy to disintegrate rapidly and completely and a preparation method thereof. Background technique [0002] Irritable bowel syndrome (IBS) is a chronic functional disease of unknown etiology, characterized by abdominal pain or discomfort and changes in bowel habits, and is a frequently-occurring disease worldwide. Calcium polycarbophil was first developed by Abbott in the United States and has been widely used in Europe, America and Japan for the relief of IBS and constipation symptoms of various causes. In September 2011, the State Food and Drug Administration approved the domestic preparation of polycarbophil calcium tablets (trade name Libofil) in China. Polycarbophil calcium tablets are also included in the 2021 edition of the National Medical Insurance List. [0003] The active ingredient of polycarboph...
