Nail polish, medical

Topically applicable therapy principle for the application of active ingredients (e.g. antimycotics) or care substances in a varnish base to fingernails or toenails (see also nail care).

• There are currently only a few medical nail polishes on the market; some of them are approved as medicinal products, while others fall under the Medical Devices Act. Various lacquer bases are commonly used in medical nail polishes (mainly nitrocellulose, collodion, hydro lacquer). Some products approved as antifungal nail polishes also use gantrez varnish (nail batrafen) or polyacrylate varnish (Loceryl) as film formers. As a rule, medical nail polish formulations adhere significantly less long or less firmly than cosmetic nail polishes and can be removed without nail polish remover or other aggressive solvents.
• In addition to antimycoticnail polishes (e.g. Ciclopirox, Amorolfin, Bifonazole, Clotrimazole), which are either licensed as finished preparations or available as extemporaneous formulations, nail polishes are also becoming increasingly popular as carriers of nourishing ingredients. The aim of their application is to protect the nail matrix, regulate moisture and remineralize. Preparations with urea (Visurea) and active ingredient combinations with hydroxypropyl chitosan, sulphur and horsetail (Sililevo) as well as octopirox and hydroxypropyl chitosan (Myfungar) are available.
