    Abstract: A method utilizing compositions for topical application which are adapted for the prevention and treatment of viral infections such as Herpes, AIDS and other envelope virus infections are disclosed. The compositions of the present invention produce a synergistic anti-viral effect when used in combination. The formulation contains a humectant such as sorbitol, glycerol, or other comparable compound in the range of 20-80% w/v final concentration, which facilitates structural and/or functional three dimensional disruption or disorientation of the viral envelope. The activation of the destruction of the envelope and subsequent death of the envelope virus is then achieved using combination of inorganic monovalent anions, nonionic detergents and anionic detergents. These monovalent anions can include sodium bicarbonate, sodium thiocyanate, sodium fluoride and sodium chloride at about 0.5 to 5% w/v final concentration; nonionic detergents such as Tween 20 at concentrations of about 0.

  • Patent number: 5208031
    Abstract: This invention relates to the use of zinc salts as anti-viral agents in sexual lubricants. A zinc salt which releases divalent zinc ions in an aqueous carrier fluid is provided in a sexual lubricant formulation which is spread on the genitals before sexual intercourse. The mixture is non-irritating, and the zinc ions serve as an anti-viral agent to reduce the risk of contracting genital herpes if a sexual partner is infected. These lubricants may also reduce the risk of infection by other sexually transmitted viral diseases, such as hepatitis, papilloma viruses, and AIDS. A preferred lubricant formulation comprises water, a thickening or suspending agent, a lubricating agent, and a suitable zinc salt. Salts which have been tested and shown to be non-irritating during sexual intercourse include zinc acetate, zinc propionate, and zinc gluconate. Other zinc salts have also been identified which are soluble in water and have low pK values, which indicates a high rate of zinc ion release.

  • Patent number: 5063209
    Abstract: The use of mismatched dsRNA, e.g., AMPLIGEN.RTM. for the manufacture of compositions for use in the selective activation of a latent natural defense system within human cells, both cells already infected with AIDS virus as well as cells at risk to infection. Specific treatments for various clinical phase of the biological continuum of AIDS virus-related events ranging from subtle, early immunological lesions to advanced disease are described. Prophylaxis or prevention of AIDS virus related events, such as by introduction of mismatched double-stranded RNA into various blood products or biological fluids to be used in man (e.g., blood transfusion) or around man (e.g., dialysis programs) are also described.

  • Patent number: 5004757
    Abstract: Very potent, stable, ordorless, and phenol-free virciudal solutions are active at high dilution when used for surface decontamination of animate and inanimate objects. The virucidal compositions described are efficacious in a matter of minutes against both the lipophilic and the more resistant hydrophilic viruses. The three active ingredients in these virucidal compositions are the glutaraldehyde monomer in equilibrium with its hydrates and polymers, hydrogen-bonded glycol molecules to eliminate aldehydes odor, and an anionic surfactant of the alkyl sulfate, alkyl sulfonate, alcohol sulfate or alkyl aryl sulfonate type. A preferred anionic surfactant would be the Sodium Dodecyl Sulfate (SDS), which exhibits strong cidal synergism against the Herpes Simplex Virus type 1 when mixed at a concentration as low as 0.0005% in diluted glutaraldehyde aqueous solutions (0.0025%). Improved virucidal killing at higher dilutions of the same formula were observed with the more resistant Coxsackie B viruses.
