1. A pharmaceutical composition comprising:
- at least one active agent comprising an opioid or a pharmaceutically acceptable salt thereof;
at least one high molecular weight polyethylene oxide (PEO), having an approximate molecular weight of from 1 million to 8 million;
optionally at least one low molecular weight PEO having an approximate molecular weight of less than 1,000,000;
wherein(a) the active agent and high molecular weight PEO are combined in a solid oral extended release dosage form that is (i) compression shaped, (ii) air cured by heated air, without compression, for a curing time of about 15 minutes to about 8 hours at a curing temperature of about 60°
C. to about 90°
C., (iii) cooled, and (iv) hardened;
(b) the high molecular weight PEO is at least partially melted upon curing and comprises at least about 50% (by weight) of the dosage form;
(c) the active agent comprises at least about 1.3% (by weight) of the dosage form;
(d) the molecular weight of each PEO is based on rheological measurements;
(e) the total weight of the dosage form is calculated by excluding the combined weight of said film coatings; and
(f) the dosage form is expanded upon curing, as measured by a decrease in density of at least about 1.5%, and the dosage form provides a hardness of at least about 439 N.

12. A pharmaceutical tablet comprising:
-
a dosage amount of least one active agent comprising an opioid or a pharmaceutically acceptable salt thereof; at least one high molecular weight polyethylene oxide (PEO) having an approximate molecular weight of from 1 million to 8 million; at least one additive comprising an anti-tacking agent, an antioxidant, an immediate release component, or a retardant; at least one film coating; and optionally at least one low molecular weight PEO having an approximate molecular weight of less than 1,000,000;
wherein(a) the active agent and high molecular weight PEO are combined in a solid oral extended release tablet that is (i) shaped by direct compression, (ii) air cured by heated air, without compression, for a curing time of at least 15 minutes at a curing temperature of at least about 65°
C., (iii) cooled at a cooling temperature below about 50°
C., and (iv) hardened;(b) the high molecular weight PEO comprises at least about 50% (by weight) of the dosage form; (c) the active agent comprises at least about 2.4% (by weight) of the dosage form; (d) the molecular weight of each PEO is based on rheological measurements; and (e) the total weight of the dosage form is calculated by excluding the combined weight of said film coatings; and (f) the dosage form is expanded upon curing, as measured by a decrease in density of at least about 1.5%, and the dosage form provides a hardness of at least about 439 N. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
