Abstract

A method of treatment or prophylaxis of amyloidosis disorders in a patient the method comprising topically applying to an area of skin of the patient a composition comprising: one or more zinc chelators; and one or more dermal penetration enhancers.

Description

technical field [0001] The present invention relates to compositions for the administration of zinc chelators such as 1,10-phenanthroline and the use of the compositions in the prevention and treatment of amyloidosis. Background technique [0002] Amyloidosis is not just one disease, but a group of diseases of acquired or hereditary origin characterized by several different types of protein filaments with similar properties called amyloid One of them was deposited extracellularly. Amyloid deposition can be a primary (primary) process with no known prodromal symptoms or a secondary process relative to certain other symptoms, and can be localized or spread throughout the body (systemic). Amyloid deposits cause a variety of common and rare diseases and may involve many different amyloid proteins. For example, Alzheimer's Disease and Creutzfeldt-Jakob disease are two distinct diseases characterized by amyloid deposits in the brain, but the proteins involved are not Not the sa...
