|---|---|---|---|---|
| Day (x) | Slope | Y | Slope | Y |
| 1 | 43.4 ±3.143 | 1.0 | 23.5 ±3.325 | 1.0 |
| 2 | 76.23 ± 6.7 | 1.7 | 29.87 ±1.782 | 1.27 |

Table 4 shows the slope values of the phase solubility curves with normalisation of slope value to day 1. Y = (slope at x day/ slope at day 1) and this indicates a comparative complexation to day 1; SBE-β-CD = sulfobutylether-β- cyclodextrin; HP-β-CD = Hydroxypropyl -β-cyclodextrin
