Nanoparticles of multi-element fine anesthetics and minoxides, preparation process, water suspension, containing the same substance, pharmaceutical ingredients, and use thereof
The invention refers to the composition of multi-element nano particles, the form of which is particles and minoxides as active components, wherein the multi-element nano particles include a liquid or semi-solid core encapsulated by a polymer solid film, including: (a) 0.05% to 20.0% (P / P). Waterborne polyurethane, selected from the police -Kavroktona;b) 0.05% to 20.0% (w / w) of a fixed oil selected from triglycerides of capric and caprylic acids; c) 0.05% to 20.0% (w / w) of a low EHL lipophilic surfactant (Lipophilic Hydrophil Balance) selected from sorbitan monostearate; d) 10% to 80% of an organic solvent selected from acetone; e) 0.001% to 50% (w / w) of a co-solvent selected from ethanol; f) 0.005% to 50% (w / w) of finasteride; g) 0.05% to 20.0% (w / w) of a hydrophilic surfactant selected from polysorbate 80; h) 0.005% to 50% (w / w) of minoxidil; and i) 10% to 90% (w / w) of water. Said composition is of topical application, being useful for the treatment of alopecia.La presente invencion se refiere a una composicion de nanoparticulas polimericas en forma de nanocapsoides que contienen finasterida y minoxidil como principios activos, donde las nanoparticulas polimericas comprenden un nucleo interno liquido o semisolido encapsulado por una membrana solida polimerica, que comprende: a) 0,05% a 20,0% (p/p) de un polimero hidrofobico, seleccionado de poli (?-caprolactona); b) 0,05% a 20,0% (p/p) de un aceite fijo seleccionado de trigliceridos de los acidos caprico y caprilico; c) 0,05% a 20,0% (p/p) de un tensoactivo lipofilico de bajo EHL (Equilibrio Hidrofilo Lipofilo) seleccionado de monoestearato de sorbitan; d) 10% a 80% de un solvente organico seleccionado de acetona; e) 0,001% a 50% (p/p) de un co-solvente seleccionado de etanol; f) 0,005% a 50% (p/p) de finasterida; g) 0,05% a 20,0% (p/p) de un tensioactivo hidrofilico seleccionado de polisorbato 80; h) 0,005% a 50% (p/p) de minoxidil; y i) 10% a 90% (p/p) de agua. Dicha composicion es de aplicacion
