Examples
Embodiment 1
[0031] A certain amount of carvedilol was placed in a beaker and dissolved with an appropriate amount of dichloromethane. Place an appropriate amount of Bio PSA-7 pressure sensitive adhesive in another beaker and stir. Mix the two solutions together until homogeneous. The mixture is then placed on the release layer and dried. Finally, put it on the backing support layer, cut it into patches of different sizes, package it and store it in a ventilated and dry place at room temperature.
[0032] The ingredients are as follows:
[0033] Element 1A 1B 1C 1D 1E Carvedilol 3% 3% 3% 3% 3% Bio PSA-74502 97% 72% 47% 22% 0 Bio PSA-74202 0 25% 50% 75% 97%
[0034] Franz transdermal permeation instrument and Spectra / Por7MWCO1000-38mm film were used to detect the drug penetration efficiency. See the attached manual for the results figure 1
Embodiment 2
[0036] The method is the same as Example 1, and the composition is as follows:
[0037] Element 2B 2C 2D 2E Carvedilol 3% 3% 3% 3% Bio PSA-74202 72% 47% 22% 0 Bio PSA-74302 25% 50% 75% 97%
[0038] For the results of drug transdermal penetration efficiency, please refer to the appendix of the instructions. figure 2 :
