Abstract: OBJECTIVE To prepare a liposome hydrogel of diclofenac sodium(DCS) and evaluate it. METHODS The DCS liposomes were prepared by the conventional thin film hydration method at first, to which the carbopol was added as a support base for preparation of the hydrogel of DCS. An one-order derivative UV spectrophotometry was established to evaluate the DCS in hydrogel.RESULTS The average recoveries of three samples were (101.1±0.86)%,(99.90±1.04)%和(100.5±0.91)%, respectively and the average encapsulation efficiency of liposomes is 43.6% after separated by gel minicolumn. The particle sizes of liposomes were determined by a coulter counter and d50 was 1.37μm. In stability of test, the hydrogel was stored for 0.5, 1, 3 or 6 months at 4℃ or at room temperature, and the encapsulated efficiency of liposomes was decreased by 4.4% or 6.8% respectively after six months.CONCLUTION:It is feasible to prepare a liposome hydrogel of DCS after an initial evaluation.
