Description
"IMPROVEMENTS RELATING TO THE TREATMENT OF WARTS
AND SORE THROATS"
The present invention relates to improvements relating to the treatment of warts and sore throats.
More particularly, this invention relates generally to remedial treatment for sore throats caused by bacterial or viral infection, and to the removal of wart (papilloma) tissue. The invention concerns compositions, medicaments incorporating same and methods for such treatments.
There exists a long recognised need for techniques or processes which will alleviate sore throat, or will remove wart (verruca) tissue including the root structure thereof. Current remedies are less than satisfactory, however.
According to the present invention, there is provided a solution composition consisting essentially of dimethyl sulfoxide and an ingredient dissolved therein, which ingredient is at least one of citric acid and citric monohydrate, for use in a method for treating a human or animal patient afflicted with a virus caused wart or verruca, wherein the method includes topically applying said solution composition to the wart for a period of time and in an amount sufficient to penetrate the wart or verruca and to remove wart or verruca tissue.
Also according to the present invention, there is providedasolution composition consisting essentially of dimethyl sulfoxide and an ingredient dissolved therein, which ingredient is at least one of citric acid and citric acid monohydrate, for use in a method for treating a human or animal patient afflicted with sore throat caused by bacterial or viral infection, wherein the method includes topically applying the solution composition to the patient's neck proximate to the sore area of the throat for a period of time and in an amount sufficient to alleviate the sore throat.
A pharmaceutical solution composition according to this invention, for use in treating a human or animal patient afflicted with a wart, to penetrate and remove wart tissue, can consist essentially of between about 90 and 40 weight parts of dimethyl sulfoxide, and between about 10 and 60 weight parts of an ingredient dissolved in the dimethyl sulfoxide, the ingredient being at least one of citric acid, and citric acid monohydrate.
A pharmaceutical solution composition according to this invention, for use in treating a human or animal patient afflicted with sore throat caused by bacterial or viral infection, by topical application of said composition to a neck region of the patient, can comprise between about 90 and 40 weight parts of dimethyl sulfoxide, and between about 10 and 60 weight parts of an ingredient dissolved in the dimethyl sulfoxide, the said ingredient being at least one of citric acid and citric acid monohydrate.
The invention comprehends use of a solution composition comprising dimethyl sulfoxide and at least one of citric acid and citric acid monohydrate for the manufacture of a medicament for the treatment of warts and verrucae.
The invention also comprehends use of a solution composition comprising dimethyl sulfoxide and at least one of citric acid and citric acid monohydrate for the manufacture of a medicament for the treatment of sore throats.
Compositions according to this invention can optionally include a small amount of lidocaine hydrochloride which, for example, is present in an amount of 0.01 to 4% of the solution by weight.
By way of example, the lidocaine hydrochloride may be 0.1 or 0.4% by weight.
The relative amounts of (a) dimethyl sulfoxide (DMSO) and (b) citric acid moiety in the compositions according to this invention will be such as to (a) ensure effective tissue penetrating ability to enable the said moiety to reach the seat of the viral or bacterial attack and (b) ensure there is adequate virus or bacteria-destroying capacity.
By way of example, the DMSO content is usually about 40% by weight or more, while the acid moiety content is usually about 10% by weight or more.
It is a major object of the invention to provide method and composition that will meet the above need.
Basically, the method of treating a virus caused benign wart (for example exposed at the skin) on a human or animal patient includes the steps:
(a) forming a solution composition consisting essentially of dimethyl sulfoxide and an ingredient dissolved therein, said ingredient selected from the group consisting of citric acid and citric monohydrate;
(b) topically applying said solution composition to the wart for a period of time and in an amount sufficient to penetrate the wart and to remove wart tissue subsequently.
The solution composition is typically formed by combining between about 10 to 60 weight percent of said ingredient and between about 80 to 40 weight percent dimethyl sulfoxide; and more specifically the preferred solution consists essentially of about 70 weight percent dimethyl sulfoxide, and about 30 weight percent of said ingredient. A small amount of lidocaine hydrochloride (0.01 to 3.9 weight percent) may be added, or included.
A preferred amount of lidocaine hydrochloride is 0.1 weight percent.
The invention is now explained further by reference to the following non-limitative Examples.
EXAMPLE I
70 (or about 70) weight parts of liquid dimethyl sulfoxide were combined with 30 (or about 30) weight parts of citric acid and stirred (30 to 60 minutes) to form the product solution, the solution temperature being between 950F to 1150F (35 to 460C). A small amount (a drop) of the resultant solution was then applied locally and topically to the exposed surface of a papilloma. After several such treatments carried out over several days (5, for example) the wart (papilloma) was easily removable from its position in the skin and subcutaneous tissue, as by lifting. The treatment may be continued for as long as necessary to enable such removal.
Since the dimethyl sulfoxide component causes citric acid penetration deeply into the wart, its root structure, containing the viral agent causing the wart, is also removable, the citric acid chemically attacking the embedded viral agent, for example to destroy same.
EXAMPLE II
Example I was repeated, except the weight percentages were about as follows:
- 90 weight % dimethyl sulfoxide
- 10 weight % citric acid
EXAMPLE III
Example I was repeated, except the weight percentages were about as follows:
- 40 weight % dimethyl sulfoxide
- 60 weight % citric acid.
EXAMPLES IV, V and VI
Examples I to III were repeated, except that citric acid monohydrate was substituted for citric acid.
EXAMPLES VII to XII
Examples I to VI were repeated, except that between 0.01 to 4.0 weight percent (and preferably about 0.1 weight percent) lidocaine hydrochloride was added to the composition and dissolved therein during the mixing, the relative weight percentages of the dimethyl sulfoxide and citric acid, or citric acid monohydrate remaining the same in the solution.
The method of treating a human or animal patient afflicted with sore throat (inflamed or painful throat-tissue) caused by bacterial or viral infection, includes the steps of:
(a) forming a solution composition consisting essentially of dimethyl sulfoxide and an ingredient dissolved therein, which ingredient is selected from citric acid and citric acid monohydrate; and
(b) topically applying the solution composition to the patient's neck proximate to the sore area of the throat for a period of time and in an amount sufficient to alleviate the sore throat.
The solution composition is typically formed by combining between about 10 to 60 weight percent of the said citric acid ingredient and between about 80 to 40 weight percent dimethyl sulfoxide; and more specifically, the preferred solution consists essentially of about 70 weight percent dimethyl sulfoxide, and about 30 weight percent of the said acid ingredient. A small amount of lidocaine hydrochloride (0.01 to 3.9 weight percent) may be added to or included in the composition, for rapid sore throat pain suppression. A preferred amount of lidocaine hydrochloride is 0.1 weight percent.
EXAMPLE I'
70 (or about 70) weight parts of liquid dimethyl sulfoxide were combined with about 30 weight parts of citric acid, and the mixture was stirred (30 to 60 minutes) to dissolve the citric acid in the dimethyl sulfoxide, forming the product solution.
A small amount (film) of the resultant solution is applied to the patient's neck region, as to the skin proximate to the carotid artery, and over an area of about 1 square inch (6.45 cam2) (1/2 to 2 2 square inches - 3.23 to 12.9 cm - also being usable). After one or more such treatments, substantial relief of throat soreness was experienced, such relief continuing for at least several hours (3 to 10 for example).
After treatment as described, such relief has been experienced, by over fifteen human patients who were suffering severely from such sore throats.
It is believed that the citric acid is carried into the throat tissue by the dimethyl sulfoxide penetrant, to destroy virus and/or bacteria which cause throat inflammation or soreness, such bacteria and virus being normally otherwise protected against treatment via the mouth, by the mucous lining of the throat.
EXAMPLE II'
Example I' was repeated, except the weight percentages were about as follows:
- 90 weight % dimethyl sulfoxide
-10 weight % citric acid.
EXAMPLE III'
Example I' was repeated, except the weight percentages were about as follows:
- 40 weight % dimethyl sulfoxide
- 60 weight % citric acid.
EXAMPLES IV', V' AND VI'
Examples I', II' and III' were repeated, except that citric acid monohydrate was substituted for citric acid.
EXAMPLES VII' to XII'
Examples I' to VI' were repeated except that between 0.01 to 4.0 weight percent (and preferably about 0.1 weight percent) lidocaine hydrochloride was added to the composition and dissolved therein during mixing, the relative weight percentages of the dimethyl sulfoxide and citric acid, or citric acid monohydrate remaining the same in the solution, which is essentially anhydrous.
Reaction products are carried away to the kidneys in body fluid, such as blood.
In the above, if the weight percent of dimethyl sulfoxide is below about 40%, the tissue penetrating capability of the solution is usually too low for sufficiently effective results; and if the citric acid and/or monohydrate weight percent is below about 10%, the virus destroying capability of the solution is usually insufficient.
