Embodiment 1
[0039] Each component was weighed according to the weight of each component of the drug storage layer and the adhesive layer in Example 1 in Table 1. After the components of the weighed drug storage layer are fully mixed and homogenized, the mixed colloid is coated on the backing layer material with a thickness of 0.65mm, and dried at 40°C in the dark for 2 hours and cooled to room temperature for later use; the weighed paste After the components of the layer are fully mixed and homogeneous, the mixed colloid is coated on the anti-adhesive protective layer material with a thickness of 0.30mm, and dried at 40°C in the dark for 2 hours and cooled to room temperature for later use; the two parts of the adhesive layer prepared above Composite with the drug storehouse layer and cut into 2.5cm by die 2 Specification embodiment 1 transdermal patch, with aluminum-plastic film airtight packaging, keep away from light for subsequent use.
Embodiment 2
[0041] Each component was weighed according to the weight of each component of the drug storage layer and the adhesive layer in Example 2 in Table 1. After the components of the weighed drug storage layer are fully mixed and homogenized, the mixed colloid is coated on the backing layer material with a thickness of 0.45mm, dried at 60°C for 2 hours and cooled to room temperature for later use; After the components are fully mixed and homogenized, the mixed colloid is coated on the anti-adhesive protective layer material with a thickness of 0.20mm, and dried at 60°C for 2 hours and cooled to room temperature for later use; The compound is punched and cut into 2.5cm by the mold 2 Specification Example 2 Transdermal patch, sealed and packaged with aluminum-plastic film, protected from light and stored for later use.
Embodiment 3
[0043] Each component was weighed according to the weight of each component of the drug storage layer and the adhesive layer in Example 3 in Table 1. After the components of the weighed drug storage layer are fully mixed and homogenized, the mixed colloid is coated on the backing layer material with a thickness of 0.70mm, dried at 60°C for 2 hours and cooled to room temperature for later use; After the components are fully mixed and homogenized, the mixed colloid is coated on the anti-adhesive protective layer material with a thickness of 0.20mm, and dried at 60°C for 2 hours and cooled to room temperature for later use; The compound is punched and cut into 2.5cm by the mold 2 Specification Example 3 The transdermal patch is sealed and packaged with aluminum-plastic film and stored away from light for subsequent use.
