Abstract

Compositions and methods for controlling and tracking items are provided. More particularly, labeling compositions useful as a coding system to deter diversion of items of medication or other valued items are provided, wherein the labeling compositions comprise at least 25 unique identifiers, wherein the at least 25 unique identifiers are selected from a set of at least 50 unique identifiers. Also provided are methods for using such compositions to provide trackability throughout a chain of custody.

Claims

1. A composition comprising,

a) at least one carrier particle, and

b) a labeling mixture associated with the at least one carrier particle, wherein the labeling mixture comprises a plurality of unique identifiers.

2. The composition of claim 1, wherein the labeling mixture comprises at least 25 unique identifiers, and wherein the at least 25 unique identifiers are selected from a set of at least 50 unique identifiers.

3. The composition of claim 2, wherein the at least 25 unique identifiers are associated with a single carrier particle.

4. The composition of claim 2, wherein each of the at least 25 unique identifiers is associated with a single carrier particle, and wherein the composition comprises at least 25 carrier particles.

5. The composition of claim 2, wherein the carrier particle is a ferrite bead.

6. The composition of claim 2, wherein the identifier is selected from the group consisting of an oligonucleotide, a pharmaceutically acceptable excipient, a dye, a peptide, an oligoglycan, a mass tag, and combinations thereof.

7. The composition of claim 6, wherein the unique identifier comprises an oligonucleotide.

8. The composition of claim 7, wherein the oligonucleotide comprises a central coding region flanked by two amplification regions.

9. The composition of claim 8, wherein the central coding region comprises about 5-10 nucleotides and wherein each amplification region comprises about 15-30 nucleotides.

10. The composition of claim 6, wherein the identifier is a dye selected from the group consisting of a colorant and a fluorescent dye.

11. The composition of claim 6, wherein the identifier is a peptide.

12. The composition of claim 6, wherein the identifier is an oligoglycan.

13. A composition for use in labeling a medication, comprising a labeling mixture that comprises a plurality of unique identifiers.

14. The composition of claim 13, wherein the labeling mixture comprises at least 25 unique identifiers, and wherein the at least 25 unique identifiers are selected from a set of at least 50 unique identifiers.

15. The composition of claim 13, wherein the unique identifiers are selected from the group consisting of an oligonucleotide, a carrier particle, a pharmaceutically acceptable excipient, a dye, a peptide, an oligoglycan, a mass tag, and combinations thereof.

16. A pharmaceutical dosage form associated with a labeling composition, wherein the labeling composition comprises a labeling mixture that comprises a plurality of unique identifiers, wherein the labeling mixture is either associated directly with the pharmaceutical dosage form or is indirectly associated with the pharmaceutical dosage form via a carrier particle.

17. The pharmaceutical dosage form of claim 16, the labeling mixture comprises at least 25 unique identifiers, and wherein the at least 25 unique identifiers are selected from a set of at least 50 unique identifiers.

18. The pharmaceutical dosage form of claim 16, wherein the dosage form is a solid oral dosage form, and wherein the labeling composition is associated with the solid oral dosage form by dusting the dosage form with the labeling composition.

19. The pharmaceutical dosage form of claim 16, wherein the labeling mixture comprises a plurality of unique identifiers associated with a carrier particle and wherein the carrier particle is a ferrite bead.

20. The pharmaceutical dosage form of claim 16, wherein the unique identifiers are selected from the group consisting of an oligonucleotide, a carrier particle, a pharmaceutically acceptable excipient, a dye, a peptide, an oligoglycan, a mass tag, and combinations thereof.

21. A method for labeling an item, comprising

a) providing an item;

b) associating the item with a labeling mixture that comprises a combination of at least 25 unique identifiers, wherein the at least 25 unique identifiers are selected from a set of at least 50 unique identifiers, and wherein the labeling mixture is either associated directly with the item or is indirectly associated with the item via a carrier particle; and

c) documenting the combination of at least twenty-five identifiers associated with the item.

22. The method of claim 21, wherein the item is selected from the group consisting of a pharmaceutical dosage form, a dermal patch, a medical device, a certificate of value, and currency.

23. The method of claim 22, wherein the pharmaceutical dosage form is a solid oral dosage form.

24. The method of claim 21, wherein the associating step is by dusting.

25. The method of claim 21, wherein the carrier particle is a ferrite bead.

26. The method of claim 21, wherein the at least 25 unique identifiers are selected from the group consisting of an oligonucleotide, a carrier particle, a pharmaceutically acceptable excipient, a dye, a peptide, an oligoglycan, a mass tag, and combinations thereof.

27. A method of identifying a labeled item comprising:

a) obtaining an item that may have been labeled with an associated labeling mixture;

b) determining the combination of at least twenty-five identifiers, if present; and

c) comparing the determined combination with documentation to identify the source of the item.

28. The method of claim 27, wherein the determining step involves the use of an epifluorescence microscope, a spectrophotometer, a Coulter counter, or a combination thereof.
