Özet
Curcumin is an important anti-inflammatory agent for the treatment of skin disorders. However, its low water solubility, poor bioavailability, and instability limit the utilization of curcumin. Semi-solid lipid nanoparticle (SLN and NLC) dispersions, which maintain their colloidal particle size despite their high viscosity, offer a novel promising approach with high potential for dermal curcumin delivery. In this study, novel semi-solid SLN-NLC formulations of curcumin were manufactured using a one-step method, without the need to disperse the nanoparticles in an additional vehicle. Modde Pro 12 was used to examine the relationship between variables and quality attributes. QbD-based formulation optimization was successfully performed using artificial neural network program (ANN), and optimum semi-solid SLN-NLC formulations were prepared. The particle size of the optimum formulations was found to be 204.7 ± 1.5 nm for SS-SLN-Opt and 198.5 ± 0.81 nm for SS-NLC-Opt, indicating that the particle sizes were within the targeted range. The amount of curcumin released from the SS-NLC-Opt formulation was 33.72 ± 4.99% at 24th Hour, which was higher than the release obtained from the eight SS-NLC formulations entered as input into the ANN program. On the other hand, while the curcumin release percentage at the 24th Hour from the SS-SLN formulations entered into the program ranged between 11.13% and 44.31%, the release amount for the SS-SLN-Opt formulation was found to be 38.34 ± 3.48%, which was within this range and close to the maximum value. Rheological characterization results indicated that the optimum semi-solid SLN and NLC formulations were more elastic than viscous. The stability of the optimum semi-solid SLN formulation at 4 °C was higher than that of the optimum semi-solid NLC after one month. In vivo studies in rats revealed that the optimum semi-solid SLN formulation exhibited higher anti-inflammatory activity than both the optimum semi-solid NLC and the conventional gel. The SS-SLN-Opt formulation effectively reduced the inflammation in rats starting from the first hour. In conclusion, the optimum semi-solid SLN formulation, which is more stable and has higher anti-inflammatory activity, is a promising alternative for the dermal delivery of curcumin.
