Table 2.

Values extracted from Kormeyer-Peppas analysis of the AI release data at pH 1.

Formulation	n	k (min−1)
S-BA	0.14	0.48
S-NA	0.28	0.16
S-NAM	0.10	0.51
S-ACA	0.36	0.055
C-BA	0.11	0.47
C-NA	0.25	0.18
C-NAM	0.22	0.27
C-ACA	NC	NC

NC = not calculated. The release percentages obtained for C-ACA at pH 1 were all very close to zero, and hence mathematical analysis could not be undertaken.
