The invention discloses a
capsule medicament for
endoscopic treatment of
ulcerative colitis and a preparation method thereof, and belongs to the technical field of biological
medicine, the
capsule medicament is composed of a
capsule matrix and a
drug matrix; by adopting a dual control mechanism of an enteric layer
coating and a pH response layer
coating, accurate release of a
medicine at a colon diseased region is ensured,
medicine waste of the
stomach and the
small intestine is reduced, the medicine concentration at a focus is improved,
mesalazine or
budesonide is combined with the composite composition for treatment,
inflammatory response is rapidly inhibited, acute symptoms are controlled, and the
curative effect is good. A multi-mechanism synergistic treatment mode is adopted, the anti-inflammatory and repairing effects are enhanced, the clinical
remission rate and the
mucous membrane healing rate are remarkably improved, the pH response layer is dissolved in a colon alkaline environment, and the MMP-9
peptide cross-linking agent is subjected to enzymolysis at an
inflammation part, so that the medicine is continuously released at a focus, the administration frequency is reduced, the compliance of a patient is improved, and the
curative effect is good. In addition, the spherical gel particles in the medicament can prevent the medicament from being disintegrated too early in the intestinal tract, and the long-acting effect can be maintained.
