(A) FTIR spectra and (B) DSC thermograph of diclofenac sodium, P-407, PF-127 alone and in combination form. Rheology studies of hydrogel, (C) P-407, (D) PF-127, (E) P-407 + PF-127, (F) Diclofenac sodium loaded P407, and (G) DS-loaded PF-127, respectively. These data showed the gel formation and mechanical stability of the fabricated hydrogels
