  • Patent number: 5213803
    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: 5089276
    Abstract: A composite which is obtainable by mixing calcium pantothenate with a per se neutral or basic magnesium or calcium lactate or carbonate in the presence of water and/or a lower alcohol, and drying the resulting mixture, is stable with little decrease of the content of calcium pantothenate during storage.When other drugs, which may cause changes as the result of combination with calcium pantothenate, are combined to produce various preparations, the composite is stable because they are hardly affected by other ingredients and hardly affect other ingredients; for example, in production of tablets, powders, granules, and capsules, complicated processes to separate from other ingredients are not required, and the excessive amount in anticipation of the loss along with time can be reduced markedly.
