https://www.selleckchem.com/products/cyclophosphamide-monohydrate.html Latanoprost has recently been used to treat alopecia as it causes an increase in the capillary density of patients. This work presents for the first time the development of polymeric nanocapsules containing latanoprost for the topical treatment of alopecia. Poly-ε-caprolactone nanocapsules loading latanoprost were developed by nanoprecipitation of the polymer on the surface of drug oily nanodroplets. The method encapsulated 93.9 ± 0.4% of the drug into nanocapsules of 197.8 (± 1.2) nm (PdI = 0.15 ± 0.01). The nanosystem presented a zeta potential equal to - 30.1 ± 1.8 mV and was stable for at least 90 days when stored at 6°C. The colloidal aqueous dispersion was non-irritating, according to the in vitro HET-CAM test. The nanocapsules improved latanoprost accumulation into the hair follicles when topically applied on porcine skin, delivering 30% more drug to these skin structures relative to the control solution (P  less then  0.05). Also, with a simple manual massage, latanoprost accumulation was increased by twofold (P  less then  0.05). In conclusion, in addition to being a stable and safe formulation, nanocapsules enhanced latanoprost accumulation into the hair follicles, being a nanosystem with high potential for use as a topical formulation for the treatment of androgenic alopecia.The main intent of this treatise was to encapsulate tamoxifen citrate (TMXC) into polymeric micellar delivery system and evaluate the influence of TMXC-loaded micelles as a promising carrier on the in vitro cytotoxicity and cellular uptake of TMXC in treatment of breast cancer. Different formulae of polymeric micelles loaded with TMXC using mixtures of different Pluronic polymers were fabricated by thin-film hydration method and evaluated for morphology, drug entrapment efficiency, particle size, surface charge, in vitro liberation of TMXC, uptake by cancer cell lines, and cytotoxic effect against breast cancer cel
