Embodiment 1
[0076]Preparation of microparticles: 1 part of 10% ethylcellulose-carbomer 934P copolymer solution in absolute ethanol, stirred in a water bath at 10°C for 20 minutes, slowly and uniformly dropped into 5 parts of 3% Span 85 liquid paraffin at 10°C , stirred for 30 min, evaporated at 60°C to remove ethanol, immediately cooled to a solid in an ice bath, centrifuged to separate liquid paraffin, precipitated, washed with petroleum ether, dried in a 37°C drying oven for 24 h, passed through a 100-mesh sieve, but not 200-mesh screen. Observe the shape under an optical microscope.
Embodiment 2
[0078] Enteric coating of microparticles: The prepared microparticles are boiled and fluidized in a fluidized bed coating device, sprayed with a 6% ethanol solution of acrylic resin, blown and dried, and the volatile solvent is discharged from the exhaust port, so that the coating thickness is uniform, Non-adhesive, enteric-coated microparticles.
Embodiment 3
