The invention relates to the technical field of
medicine, and particularly discloses
sulindac external gel emplastrum and application thereof.The
sulindac and a functional matrix with hydrophilic amino functional groups are subjected to molecular self-
assembly, the functional matrix and carboxyl of the
sulindac are subjected to non-
covalent interaction through
hydrogen bonds, ionic bonds and the like, and the sulindac external gel emplastrum is obtained. The stable micromolecular hydrogel with the three-dimensional
network structure is spontaneously formed. The hydrogel can be prepared into an external gel emplastrum through simple compounding, the three-dimensional
network structure endows the gel emplastrum with appropriate
viscosity and
skin adhesiveness, and the gel emplastrum can be tightly attached to the
skin after being smeared on painful parts (such as joints and muscles) and is not prone to falling off due to movement. The preparation process has the advantages of simplicity and convenience in operation, economy and high efficiency, complex equipment is not needed in the micromolecule self-
assembly process, the gel emplastrum can be compounded only through simple mixing, industrial production is facilitated, and the preparation method has high clinical conversion value and application potential.
