Publication number: 20060165747Abstract: An activator comprising a biocompatible base and a known fungicide in the form of an acid salt are mixed together by the user shortly before being applied to the infection so as to react them chemically to produce the free base of the fungicide thereby rendering the composition capable of penetrating throughout the infected tissue. The free base form has been found to be much more lethal to the fungal infection, particularly in the treatment of onychomycosis. The activator is formulated to be mixed within a few days of or just before application with the fungicide, e.g., terbinafine hydrochloride (an acid salt). Although the free base is subject to degradation and has a shorter shelf life, it was found that mixing just prior to use eliminates problems that could be caused by degradation of an active ingredient. A preferred activator solution also contains a penetration enhancer and a tissue softener.Type: ApplicationFiled: January 24, 2005Publication date: July 27, 2006Inventor: David Rolf

Patent number: 6620436Abstract: The invention provides a mixing and dispensing pouch for applying a wound dressing onto a wound. The pouch includes a pair of superimposed sheets, e.g., of plastic film, connected together at their edges. A pressure-rupturable seal is located between the super-imposed sheets and extends from one edge of the package to the other to form two compartments. The pressure-rupturable seal can be forced open manually by applying pressure on the exterior of the package with the hands so as to increase the hydrostatic pressure in a liquid, e.g., water contained in one compartment of the package causing the seal to rupture and the liquid to spurt through the ruptured seal, mixing with a dry wound dressing contained in the other compartment. If required, additional kneading of the package with the hands will mix the wound dressing for use as soon as it is expelled from the package.Type: GrantFiled: November 28, 1994Date of Patent: September 16, 2003Assignee: LecTec CorporationInventor: David Rolf
