For mechanical allodynia, the antinociceptive effect was maintained for 48 h after treatment interruption only with CHNCCaps. In conclusion, CHNCCaps is a promising formulation for treating peripheral neuropathic pain.The aim of this work was to ascertain the ability of electronic nicotine delivery systems (ENDS) to deliver drug nanocrystals through the produced aerosol. A nanocrystal nanosuspension of beclomethasone dipropionate, a synthetic chlorinated corticosteroid diester commonly used by inhalation in the treatment of asthma and chronic obstructive pulmonary disease, was prepared with a wet media milling technique using Poloxamer 188 as stabilizer. The obtained nanosuspension was thoroughly characterized by different techniques transmission electron microscopy, photon correlation spectroscopy, X-ray powder diffractometry and Fourier transform infrared spectroscopy. The nanosuspension was then loaded in the cartomizer of the electronic cigarette and the produced aerosol was collected and analysed, confirming the presence of drug nanocrystals. The results of this study suggested the possible alternative use of ENDS as medical device for the delivery of poorly soluble drugs.In nature, the combination of composition, structure, and shape determines the matter's functional performance to a large extent. Inspired by which, two electrospun Janus nanofiber formulations were created using side-by-side electrospinning in this work. Tamoxifen citrate (TAM) was used as a model drug and ethyl cellulose (EC) and polyvinylpyrrolidone K60 (PVP) as the polymer carrier matrices. The fibers have linear cylindrical morphologies and distinct Janus structures by scanning electron microscopy. One side of the fibers took a round shape, while the other was crescent-shaped. The drug was present in both polymer matrices in th
