Methods of producing stabilized solid dosage pharmaceutical compositions containing morphinans
DCFirst Claim
1. A granule substantially resistant to oxidative degradation of oxycodone, the granule comprising an interior region substantially comprising oxycodone and an exterior region substantially comprising at least one excipient selected from the group consisting of a binder, a filler, an antioxidant, a chelating agent, and combinations thereof, wherein the exterior region surrounds the interior region, and wherein the granule contains less than about 0.5% w/w of the total mass of oxycodone of each of any one or more of a degradant selected from 10-hydroxy oxycodone, di-hydroxy oxycodone, and oxycodone n-oxide after being stored for 6 months at 40°
- C. and 75% relative humidity.

15. A granule substantially resistant to oxidative degradation of a morphinan, the granule prepared by a process comprising granulating a mixture comprising the morphinan and at least one excipient chosen from a binder, a filler, an antioxidant, a chelating agent, and combinations thereof in a manner such that substantially all of the morphinan is surrounded by the at least one excipient, thereby forming the morphinan-protected granule;
- when the morphanin is oxycodone, the granule contains less than about 0.5% w/w of the total mass of oxycodone of one or more of a degradant selected from 10-hydroxy oxycodone, di-hydroxy oxycodone, and oxycodone n-oxide, after being stored for 6 months at 40°
