The film coating machine can be used in the preparation process of the antipyretic patch, and the drug ingredient is coated on the antipyretic patch substrate by coating to prepare a coating film.
Membrane method
The following are the general film making methods:
Substrate preparation: Cut the substrate to an appropriate size, and clean and disinfect the surface.
Preparation of coating solution: dissolve the drug ingredients in an appropriate solvent, add adhesives, plasticizers and other auxiliary agents, and stir evenly.
Coating film: Pour the coating solution into the coating tank, and then apply the coating solution evenly on the surface of the substrate through a film coating machine to form a thin film layer.
Drying: Place the coated substrate under proper conditions to allow it to dry.
Cutting and packaging: Cutting and packaging the dried coated film base material to prepare a heat-reducing patch product.
NBCHAO reminds you: Different drug ingredients and substrate materials require different film-making conditions and parameters, so the preparation process needs to be optimized and adjusted according to specific conditions.
