The invention discloses a gastric-soluble sustained-release tablet for preventing and treating
helicobacter pylori infection and a preparation method of the gastric-soluble sustained-release tablet. The gastric-soluble sustained-release tablet comprises an
active component and a sustained-release auxiliary material, the
active component comprises a
CagA protein targeting polypeptide, the
CagA protein targeting polypeptide is a target HpCagA
protein C terminal, and the
amino acid sequence is shown as SEQ ID NO: 1. According to the sustained-release tablet,
cell penetrating polypeptide targeting
CagA protein is taken as an
active ingredient, the effect is achieved by blocking CagA
phosphorylation and downstream
signal channels, meanwhile, the gastric-soluble sustained-release
dosage form design is combined, the local high-concentration and long-acting effect is achieved, the dual effects of
toxicity reduction and bacterium control are achieved, and the problems of
drug resistance and side effects of
antibiotics are solved.
