Oxygen-impervious packaging with optional oxygen scavenger, stabilized thyroid hormone compositions and methods for storing thyroid hormone pharmaceutical compositions
First Claim
1. A thyroid hormone pharmaceutical composition in solid unit oral dosage form comprising an effective amount of levothyroxine for treating a human in need of levothyroxine treatment and a pharmaceutical excipient, wherein said thyroid hormone pharmaceutical composition, when stored in a sealed oxygen impermeable container after about 90 days of storage at accelerated aging conditions, has a thyroid hormone potency which is at least about 3.5% greater than when said thyroid hormone pharmaceutical composition is stored in a sealed oxygen permeable container under similar accelerated aging conditions.

16. A method of packaging a thyroid hormone pharmaceutical composition in solid unit oral dosage form, said method comprising:
-
(1) depositing said thyroid hormone pharmaceutical composition in an oxygen impermeable container under reduced oxygen conditions; and
(2) sealing the container.
-
-
17. A thyroid hormone pharmaceutical composition in solid unit oral dosage form comprising an effective amount of thyroid hormone for treating a human in need of thyroid hormone treatment and a pharmaceutical excipient, wherein said thyroid hormone pharmaceutical composition is stored in a sealed oxygen impermeable container, wherein said container is purged with nitrogen to remove oxygen before being sealed.
-
18. A pharmaceutical package containing a thyroid hormone pharmaceutical composition in solid unit oral dosage form comprising a sealed oxygen impermeable container purged with nitrogen to remove oxygen before being sealed, wherein said thyroid hormone pharmaceutical composition has a thyroid hormone potency which is at least about 21.6% greater after about 28 days of storage at accelerated aging conditions in said sealed oxygen impermeable container, than when said thyroid hormone pharmaceutical composition is stored under accelerated aging conditions for the same period of time in a sealed oxygen permeable container which is not purged with inert gas to remove oxygen before being sealed.
-
19. A method of packaging a thyroid hormone pharmaceutical composition in solid unit oral dosage form comprising:
-
(1) depositing said thyroid hormone pharmaceutical composition within a container;
(2) purging the container with inert gas to remove oxygen; and
(3) sealing the container.

20. A thyroid hormone pharmaceutical composition in solid unit oral dosage form comprising an effective amount of thyroid hormone for treating a human in need of thyroid hormone treatment and a pharmaceutical excipient, wherein said thyroid hormone pharmaceutical composition, when stored in a sealed container comprising an oxygen scavenger after about 90 days of storage at accelerated aging conditions, has a thyroid hormone potency which is at least about 8.3% greater than when said thyroid hormone pharmaceutical composition is stored in a sealed container which does not comprise an oxygen scavenger under similar accelerated aging conditions.
-
21. A pharmaceutical package containing a thyroid hormone pharmaceutical composition comprising a sealed container having reduced oxygen content, further comprising an oxygen scavenger, wherein said thyroid hormone pharmaceutical composition has a thyroid hormone potency which is at least about 8.3% greater after about 90 days of storage in said container at accelerated aging conditions, than when said thyroid hormone pharmaceutical composition is stored in a sealed container which does not comprise an oxygen scavenger under similar accelerated aging conditions.
-
22. A method of packaging a thyroid hormone pharmaceutical composition in solid unit oral dosage form to provide increased thyroid hormone potency after about 90 days of storage at accelerated aging conditions, comprising:
-
(1) depositing said thyroid hormone pharmaceutical composition in a container with an oxygen scavenger under reduced oxygen conditions; and
(2) sealing the container;
to provide a thyroid hormone pharmaceutical composition having a thyroid hormone potency which is at least about 8.3% greater after about 90 days of storage in said sealed container at accelerated aging conditions, than when said thyroid hormone pharmaceutical composition is stored in a sealed container which does not comprise an oxygen scavenger for about 90 days under accelerated aging conditions.
