Experimental parameters
| Dissolution apparatus | RT612-ST 12 Positions Automated Dissolution tester |
| Method | USP <724> DRUG RELEASE: Apparatus 6 (Cylinder) |
| Temperature | 37℃ ± 0.5℃ |
| Speed | 50 RPM |
①Reproducibility: The RSD range of Sample 1 was 0.63~2.85% while Sample 2 was 1.35~2.99%.
②Distinguish: Under this dissolution method, there is a significant difference between Sample 1 and Sample 2 in terms of in vitro release behavior. It indicates that the method has good discrimination between Sample 1 and Sample 2
CONCLUSION: The RT612-ST provides good reproducibility and discrimination for in vitro performance testing of patches.
