Table 3. Chemical compositions and gelation temperatures of hydrogel formulations.
| Samples | P407, w/v% | Drug, w/w% | Sol-gel transition, °C | |
|---|---|---|---|---|
| Tgela | Tgelb | |||
| P407 | 20 | 0 | 24 | 24.4 |
| P407-DSP | 20 | 3 | 24 | 24.1 |
| P407-DEX | 20 | 3.02 ± 0.07 | 24 | 23.9 |
P407 = poloxamer 407, DSP = dexamethasone sodium phosphate, DEX = dexamethasone, Tgel = gelation temperature.
aSol-gel transition temperature determined using the tube tilting method.
bSol-gel transition temperature determined via rheological measurement.
