This study aimed to investigate the feasibility of producing semisolid formulations based on nanocapsule suspensions containing the association of the coenzyme Q10 and vitamin E acetate by adding gellan gum (2%) to the suspensions. Furthermore, we studied their application as an alternative for the treatment of inflammation induced by ultraviolet B (UVB) radiation. For this, an animal model of injury induced by UVB-radiation was employed. All semisolids presented pH close to 5.5, drug content above 95% and mean diameter on the nanometric range, after redispersion in water. Besides, the semisolids presented non-Newtonian flow with pseudoplastic behavior and suitable spreadability factor values. The results also showed that the semisolid containing coenzyme Q10-loaded nanocapsules with higher vitamin E acetate concentration reduced in 73±8% the UVB radiation-induced ear edema. Moreover, all formulations tested were able to reduce inflammation parameters evaluated through MPO activity and histological procedure on injured tissue and the semisolids containing the nanoencapsulated coenzyme Q10 reduced oxidative parameters assessment through the non-protein thiols levels and lipid peroxidation. This way, the semisolids based on nanocapsules may be considered a promising approach for the treatment and prevention of skin inflammation diseases.
