Effect of drug loading on the estimated release rates and release indices according to Peppas model equation

Drug loading	Release rate constant (K, day−1)	Regression coefficient (R2)	Release index (n)
9% 5-fluorouracil	40.43 ± 0.47	0.97	0.075 ± 0.005
9.5% 5-fluorouracil	35.29 ± 0.39	0.92	0.069 ± 0.002
10% 5-fluorouracil	32.76 ± 0.32	0.98	0.071 ± 0.004

Note: The samples are all loaded by the in-situ method.
