Abstract
A novel formulation having anti-viral and spermicidal properties has been developed. The formulation contains lipid vesicles having an outer bilayer formed of a non-ionic amphiphile, a surfactant such as having spermicidal and/or anti-viral activity, an oil and a sterol. The selection of the components making the vesicle is such that the formulation provides rapid spermicidal or anti-viral activity. The formulation and methods of the invention are particularly useful in the mucous membranes such as the vaginal tract and has been tested against viruses such as HIV and Vaccinia.
