Description
Use of Silver Sulfadiazine for Viral Ailments, and Preparations and Combinations Therefor
Field of the Invention
This invention relates generally to the treatment of viral ailments manifesting through a patient's skin, and particularly, to the use of Silver Sulfadiazine to treat such ailments
Background of the Invention
Silver Sulfadiazine, chemically illustrated in Figure 1, was first patented by Charles L Fox, Jr on September 25, 1973, in U S Patent 3,761 ,590 This invention of Silver Sulfadiazine combined two previously- known antibacterial agents for burns, silver nitrate and sulfadiazine, to create a synergistic compound that is extremely effective against infection
For many years, Silver Sulfadiazine, which is a broad-spectrum antimicrobial agent with bactericidal activity against most g+ and g- bacteria as well as yeast, has been used particularly for the treatment of burns In particular, burn patients frequently die of infections following sever burning, rather than the burns themselves Silver Sulfadiazine, acting as a topical antibiotic, has been very effective for controlling bacterial and fungal infections following burns, by directly killing the bacteria or fungus
Over the years, Silver Sulfadiazine has occasionally been applied in other ways, but always to kill bacterial or fungal infections Thus, for example, catheters impregnated with chlorhexidine-silver sulfadiazine are commercially available to prevent lntravascular catheter-related infections associated with central venous catheters (Mermel, Leonard A , New Technologies to Prevent lntravascular Catheter-Related Bloodstream Infections, CDC Emerging Infectious Diseases, Vol 7, No 2, March-April 2001, pp 197-199 )
Silver Sulfadiazine, as a pharmaceutical product, is prepared exclusively at a strength of 1% Because pharmaceutical protocols require use of medicinal compounds at the minimum strength required to be medically effective, this means that Silver Sulfadiazine distributed at less than 1% strength would not be effective against the bacterial and fungal ailments for which it is used and there would thus be no motivation to prepare a lesser strength compound absent the discovery of some other uses not yet known in the prior art
It would be desirable to treat viral ailments manifesting on a patient's skin, such as herpes, fever blisters, cold sores, Chicken Pox, and genital and other warts, in a manner as simply and effectively as Silver Sulfadiazine is used to treat burns It would also be desirable to employ Silver Sulfadiazine at a strength of less than 1%, if it can be effective at such lesser strengths against ailments for which it has not been heretofore used
Summary of the Invention
The invention disclosed comprises novel and inventive uses of Silver Sulfadiazine, and associated preparations and combinations These include a method of treating a viral ailment, comprising the step of applying Silver Sulfadiazine proximate a site upon a person's skin where said viral ailment is manifest, using Silver Sulfadiazine to treat a viral ailment, and distributing Silver Sulfadiazine to treat a viral ailment Also disclosed is a medically-prescriptive combination for treating a viral ailment, comprising Silver Sulfadiazine, and instructions to use said Silver Sulfadiazine to treat a viral ailment Further disclosed is Silver Sulfadiazine prepared at various strengths of less than 1%, as well as preparing Silver Sulfadiazine at various strengths of less than 1% These strengths may be suitable for the viral ailments disclosed, although they are not strong enough for bacterial and fungal ailments for which Silver Sulfadiazine is ordinarily used
Brief Description of the Drawings
The features of the invention believed to be novel are set forth in the appended claims. The invention, however, together with further objects and advantages thereof, may best be understood by reference to the following description taken in conjunction with the accompanying drawing(s) summarized below.
Figure 1 illustrates the chemical structure of Silver Sulfadiazine as known in the prior art.
Figure 2 schematically illustrates the application of Silver Sulfadiazine to a variety of viral ailments manifested on the epidermal layer of a patient's body.
Detailed Description
While Silver Sulfadiazine is generally known to be effective in the topical treatment of bacterial and fungal infections, particularly in connection with severe burns, it turns out in accordance with the invention, following preliminary experimental testing, that it is also effective in treating the following viral ailments: 1) Heφes 1 (Fever Blisters & Cold Sores); 2) Heφes II (Oral and Vaginal / Genital); 3) Heφes Zoster (Shingles); 4) Chicken Pox; and 5) Genital Warts. These uses of Silver Sulfadiazine appear to be novel and inventive over the prior art.
Figure 2 schematically illustrates the application of Silver Sulfadiazine to treat skin-layer symptoms of the above-noted viral ailments. Preferably, this application is topical, with the Silver Sulfadiazine delivered via a cream. All suitable bases ordinarily used for prevention and treatment of bacterial and fungal superinfection may also be employed for antiviral treatments. Alternatively, this application may be non-topical, via a suitable means for non- topical delivery.
As noted earlier, Silver Sulfadiazine is ineffective against bacterial and fungal infections at less than 1% strength. In preliminary testing, it appears that Silver Sulfadiazine may be effective against the aforementioned viral ailments at a lower strength of .9%, .7%, .5%, and even .3%, in contrast to the 1% strength required to treat bacterial and fungal ailments. Only once it is known that a strength less than 1% is effective for manifestations of viral ailments, would there be any motivation to prepare Silver Sulfadiazine at such a lesser strength. Thus, given the bacterial and fungal ailments which Silver Sulfadiazine is known to treat effectively but only at 1% or greater strength, and given the absence of the above-disclosed viral treatments in the prior art, it is also novel and inventive to prepare Silver Sulfadiazine with the above-noted strengths under 1%.
While only certain preferred features of the invention have been illustrated and described, many modifications, changes and substitutions will occur to those skilled in the art. It is, therefore, to be understood that the appended claims are intended to cover all such modifications and changes as fall within the true spirit of the invention.
