- Abstract
A formulation of an adapalene nanohydrogel (ADP-NH) using different surfactants and cosurfactants for topical application was developed and characterized. The best formulation was obtained with nanohydrogel (NH) containing Tween-80- (NH-Tween-80-) incorporated carbopol-940 and ethanol, 0.67% and 3.00% w / w , respectively. The optimized formulations of NH-Tween-80, nanohydrogel containing sodium lauryl sulphate (NH-SLS), and nanohydrogel containing glycerol (NH-glycerol) were separately evaluated to examine their in vitro and ex vivo permeability characteristics and compared with 0.3% dimethyl sulfoxide (control) solution. The polydispersity index of NH-Tween-80, NH-SLS, and NH-glycerol were found to be 0.264 ± 0.312 , 0.382 ± 0.0045 , and 0.310 ± 0.412 , respectively. All NH formulations showed pH within human skin pH ranges throughout the stability period. The NH-Tween-80 revealed 191.22 μg/mL of ADP permeation through Strat-M® membrane which was statistically significant (p < 0.05) compared to NH-SLS, NH-glycerol, and control solution. At 24 h, NH-Tween-80 demonstrated 305.11 μg/mL of ADP permeation in Wistar rat abdominal skin which was 1.99-, 1.56-, and 4.89-fold higher in comparison with NH-SLS, NH-glycerol, and control solution, respectively. Moreover, the ex vivo permeability of NH-Tween-80 was also compared with conventional gel (market sample) which was 3.38-fold greater at 24 h. During the 6th month of accelerated stability analysis, the NH-Tween-80, NH-SLS, and NH-glycerol demonstrated 99.25 % ± 0.15 , 91.23 % ± 0.41 , and 96.08 % ± 0.20 drug content, respectively. There were no noticeable physical changes observed up to 6 months for NH-Tween-80, while color change was observed in the 1st month and 3rd month of accelerated stability samples of NH-SLS and NH-glycerol, respectively. In this study, only NH-Tween-80 was considered both physically and chemically stable formulation. Therefore, it was concluded that the topical application of ADP-NH containing Tween-80 could be a very promising alternative for the treatment of acne vulgaris.
