The application discloses a 3D printing combination tablet for treating
helicobacter pylori infection, which comprises three
layers from top to bottom, wherein the first layer is a
stomach floating delayed release layer, the second layer is a
bismuth agent
immediate release layer, and the third layer is an enteric layer; the
stomach floating delayed release layer comprises a delayed release shell, an antibiotic inner core and an
air chamber, the delayed release shell is wrapped outside the antibiotic inner core and the
air chamber, and the
air chamber is arranged above the antibiotic inner core; the enteric layer comprises an enteric shell and a
proton pump inhibitor tablet core, and the enteric shell is wrapped outside the
proton pump inhibitor tablet core; and a
drug release channel is arranged at the bottom of the
stomach floating delayed release layer. The 3D printing combination tablet can realize the
immediate release of the
bismuth agent, the delayed release of the antibiotic and the pH-dependent release of the
proton pump inhibitor in the quadruple
drug formula, and solves the problems of complex taking sequence, poor
patient compliance and single
drug dosage of the drug formula for treating
helicobacter pylori infection on the market.
