ABSTRACT Transdermal nicotine patches have been used in smoking cessation therapy, suggested for the treatment of skin disorders with eosinophilic infiltration and have been found to improve attention performance in patients with Alzheimer's disease and age-associated memory impairment. However, skin irritation with extended patch use is still a problem. The aim of this work was to develop a simple to prepare liquid crystalline system containing vitamin E TPGS that would be able to control nicotine delivery and reduce irritation and sensitization problems. The liquid crystalline phases were macroscopically characterized by visual analysis and examined microscopically under a polarized light microscope. Topical and transdermal delivery of nicotine were investigated in vitro using porcine ear skin mounted on a Franz diffusion cell. Nicotine skin permeation from the developed cubic phase followed zero-order kinetics (r = 0.993) and was significantly enhanced after 12 h when compared to the control formulation (nicotine solution) (p < 0.05) (138.86 ± 20.44 and 64.91 ± 4.06 μg/cm2, respectively). Cubic phase was also able to target viable skin layers in comparison to control solution (8.18 ± 1.89 and 2.63 ± 2.51 μg/cm2, respectively). Further studies to evaluate skin sensitization and irritation are now necessary.

The aim of this study was to develop and validate a method for evaluating the release and skin permeation from transdermal nicotine patches using the vertical diffusion cell (VDC). The VDC is an experimental apparatus employed in research, development, and the pharmaceutical field because it can simulate conditions closest to those established in clinical trials. Two transdermal nicotine delivery systems marketed in Brazil to release 14 mg over 24 hours were evaluated. Release studies were carried out using a regenerated cellulose dialysis membrane and permeation studies were carried out using excised porcine ear skin. The results indicated that nicotine release from both evaluated patches follows Higuchi's release kinetics, while skin permeation studies indicated zero-order release kinetics. Nicotine release rates were different between both evaluated patches, but drug permeation rates were not significantly different. According to validation studies, the method was appropriate for evaluating in vitro performance of nicotine patches. The proposed method can be applied to in vitro comparative studies between different commercial nicotine patches and may be used as an auxiliary tool in the design of new transdermal nicotine delivery systems.

A three-factor three-level Box-Behnken design(BBD) was employed to optimize capsaicin-loaded nanoparticles(Cap-NPs), and its properties in vitro and in vivo were evaluated. Particle size, morphological characteristics, entrapment efficiency of Cap-NPs were investigated respectively by Zetasizer, H7000 TEM and HPLC. Release, skin permeation and skin irritation test were investigated on mouse and rabbits. The predicted values of Cap-NPs were 94.50±6.33% for entrapment efficiency(EE) and 170.30±7.81 nm for particle mean diameter(PMD) under optimal conditions which were 346.33 bar (homogenization pressure, X1), 4.67 min(homogenization time, X2), and 15421.42 rpm (shear rate, X3). The in vitro permeation study showed that capsaicin permeability in NPs-gel was a 2.80-fold greater flux values than conventional ointment after 24 h. Cap-NPs-gel produce no observable skin irritation in rabbits within 72h. The optimized Cap-NPs-gel would be a good candidate for transdermal delivery.
