Iodine preparation composition
View Patent ↗An iodine preparation composition suitable for use on wounds comprising an iodide source, an oxidant and a buffer characterized in that the iodide is held separately from the oxidant until the point of use, and that the buffer is capable of maintaining the pH of the composition at between pH 45 and pH 6 so that iodine is generated at a physiologically acceptable dose rate.
1. An iodine preparation suitable for use on wounds comprising:
(A) a first part comprising an iodide source; and
(B) a second part comprising an oxidant and a buffer;
wherein (1) said first part and said second part are combined at the point of use, (2) when said first part and said second part are combined, the iodide source is present in an amount that is 0.2 to 2 wt % of the combined two parts, (3) when said first part and said second part are combined at the point of use, the buffer maintains the pH of the combined two parts at between 4.5 and 6, and (4) when said first part and said second part are combined at the point of use, iodine is generated at a rate of 5 to 1500 micrograms per one gram of the combined two parts per hour.
2. The iodine preparation as claimed in claim 1 characterized in that the combined iodide source, oxidant and buffer generates 100 μg of iodine per g of combination per hour.
3. The iodine preparation as claimed in claim 1 formulated so that the combined iodide source, oxidant and buffer generates the said levels of iodine over a period of three days.
4. The iodine preparation as claimed in claim 1 wherein the pH of the combined iodide source, oxidant and buffer is maintained between about 5.4 and 5.8.
5. A method of treating a wound comprising applying to said wound an effective wound treating amount of an iodine preparation as claimed in claim 1 .
6. A method of treating sepsis in wounds comprising applying to said wound an effective sepsis treating amount of an iodine preparation as claimed in claim 1 .
