Composition and method for humane euthanasia of animals
View Patent ↗A novel euthanasia composition for animals, especially companion animals, utilizes a combination of sodium pentobarbital with dibucaine. The composition is easy to administer, fast-acting and relatively painless. A humane method for euthanasia involves administering the composition to animals for which euthanasia is desired.
1. A composition, suitable for euthanasia of an animal, comprising on a weight/volume basis:
a) about 5 to about 60% of sodium pentobarbital; and
b) 1% of an anesthetic consisting essentially of dibucaine; said composition containing no lidocaine.
2. The composition as claimed in claim 1 , further comprising one or more formulation agents.
3. The composition as claimed in claim 2 , wherein said formulation agent is a solvent.
4. The composition as claimed in claim 3 , wherein said formulation agent is at least one member selected from the group consisting of alcohols and polyols.
5. The composition as claimed in claim 4 , wherein said alcohol is isopropyl alcohol and said polyol is propylene glycol.
6. The composition as claimed in claim 2 , further comprising water.
7. The composition as claimed in claim 1 , wherein said composition is a solution.
8. A euthanasia composition suitable for use on a companion animal, comprising:
a) about 20 to about 30% of a euthanizing agent consisting essentially of sodium pentobarbital;
b) 1% of an anesthetic consisting essentially of dibucaine;
c) one or more solvents; and water; wherein said composition contains no lidocaine.
9. The composition of claim 8 , wherein said solvent is at least one alcohol.
10. The composition of claim 8 , wherein said solvent is at least one polyol.
11. The composition of claim 8 , further comprising at least one dye.
12. The composition of claim 9 , wherein said alcohol is isopropyl alcohol.
13. The composition of claim 10 , wherein said polyol is propylene glycol.
14. A euthanasia formulation, comprising on a weight/volume basis:
a) about 20 to about 30% of a euthanizing agent consisting essentially of sodium pentobarbital;
b) 1% of an anesthetic consisting essentially of dibucaine;
c) about 5 to about 10% of a formulation alcohol;
d) about 15 to about 25% of a formulation polyol; and
e) water; wherein said formulation contains no lidocaine.
15. The formulation of claim 14 , wherein said sodium pentobarbital is present in an amount of at least about 25%.
16. The formulation of claim 14 , wherein said formulation alcohol is isopropyl alcohol.
17. The formulation of claim 16 , wherein said formulation alcohol is present in an amount of not greater than about 8%.
18. The formulation of claim 16 , wherein said formulation polyol is a glycol.
19. The formulation of claim 18 , wherein said glycol is propylene glycol.
20. The formulation of claim 18 , wherein said glycol is present in an amount of at least about 20%.
21. The formulation of claim 14 , wherein said formulation is syringed with dye.
22. A method of euthanatizing an animal, which comprises administering a composition containing sodium pentobarbital in an amount of about 20 to about 30% by weight/volume and an anesthetic consisting essentially of dibucaine in an amount of 1% by weight/volume.
23. The method of claim 22 , wherein said method comprises administering substantially no lidocaine.
24. The method of claim 22 , wherein said composition is administered at a dose of about 2 milliliters per up to about 10 pounds of animal weight.
25. The method of claim 24 , wherein said composition is administered at a dose of about 1 milliliter for each additional 10 pounds of animal weight.
26. The method of claim 22 , wherein said method comprises administering said composition intravenously, intraperitoneally, intrathoracically, or intracardially.
27. The method of claim 22 , wherein said method comprises administering a solution of said composition.
28. The method of claim 22 , wherein said method is useful on companion animals.
29. The method of claim 28 , wherein said companion animals are selected from the group consisting of dogs and cats.
30. The method of claim 26 , wherein said composition is administered with a dye.
31. The method of claim 22 , wherein said composition is administered with at least one formulation agent.
32. The method of claim 31 , wherein said formulation agent is selected from the group consisting of isopropyl alcohol and propylene glycol.
33. A euthanasia formulation, comprising:
a) about 23 to about 28% w/v of sodium pentobarbital;
b) 1% w/v of an anesthetic consisting essentially of dibucaine;
c) about 5 to about 10% w/v of isopropyl alcohol;
d) about 15 to about 25% w/v of propylene glycol; and water; wherein said formulation contains no lidocaine.
34. The formulation of claim 33 , further comprising a dye.
35. The formulation of claim 34 , wherein said dye is blue coloring.
36. The formulation of claim 33 , wherein said formulation is administered to a companion animal at the rate of about 2 mL per 10 pounds of animal weight.
37. The formulation of claim 36 , wherein said formulation is further administered to said animal at a rate of about 1 mL per 10 pounds of additional animal weight.
38. The formulation of claim 33 , wherein said formulation is in the form of a solution.
39. The composition of claim 1 , wherein said composition is in the form of a solution.
40. The composition of claim 1 , wherein said composition is not a suspension.
41. A method for humane euthanasia, which comprises administering a composition to a companion animal at a dosage of about 1–2 milliliters up to about 10 pounds of animal weight and 1 milliliter for every 10 pounds thereabove, said composition containing about 23% to about 28% w/v of sodium pentobarbital, 1% w/v of dibucaine, at least one solvent, and water; said composition containing no lidocaine.
42. The method of claim 41 , wherein said composition is administered intravenously.
43. The method of claim 42 , wherein said composition is administered intraperitoneally.
