Embodiment 3
[0075] L-Stepherine Sustained Release Patch
[0076] A: Drug storehouse layer
[0077] L-Stepherine 10%
[0078] Polyacrylic resin 60%
[0079] Ethyl acetate 30%
[0080] Lauryl Alcohol 5%
[0081] B: Adhesive layer
[0082] L-Stepherine 3%
[0083] Polyacrylic resin 65%
[0084] Ethyl acetate 32%
[0085] Lauryl Alcohol 5%
[0086] Preparation process: Dissolve L-stephenidine and polyacrylic acid resin in ethyl acetate, mix them, add lauryl alcohol, coat the drug library ingredients on the aluminum-plastic film, dry at low temperature, recover the solvent, and take the pre-prepared polyacrylic acid resin. The propylene controlled release film is compounded with it. Another viscose component was coated on a 200 μm thick anti-sticking silicon paper, and after drying to remove the solvent, the viscose layer was obtained. Composite the viscose layer and the controlled-release membrane surface, and cut into ...
