Fig. 3From: Skin absorption of felbinac solid nanoparticles in gel formulation containing l-menthol and carboxypolymethyleneIn vitro penetration profile (A) and AUCpenetration (B) of FEL-MP and FEL-NP gels. A Franz diffusion cell with rat skin was used. n = 8. * P < 0.05, vs. FEL-MP gel for each category. The penetration of FEL-NP gel was significantly increased compared with FEL-MP gelBack to article page
