  • the tablet composition consists of;

    (a) about 1-70% w/w of the opioid; and

    (b) about 30-98% w/w of a polyethylene oxide (PEO) selected from the group consisting of (i) a single PEO having an average molecular weight of from about 400,000 daltons to about 900,000 daltons and (ii) two or more PEOs having a combined average molecular weight of from about 400,000 daltons to about 900,000 daltons and, optionally,(c) a stabilizer selected from one or more of tripropylene glycol (TPG), tocopherol polyethylene glycol succinate (TPGS), butylated hydroxytoluene (BHT), butylated hydroxyanisole (BHA), t-butyl hydroquinone, calcium ascorbate, gallic acid, hydroquinone, maltol, octyl gallate, sodium bisulfite, sodium metabisulfite, tocopherol, citric acid, tartaric acid, ascorbic acid, phosphite, erythorbic acid, etidronic acid, hypophosphorous acid, nordihydroguaiaretic acid, propionic acid, dodecyl gallate, octyl gallate, 1,3,5-trihydroxybenzene, calcium ascorbate, sodium ascorbate, sodium bisulphite, sodium metabisulfite, sodium sulfite, potassium bisulphite, potassium metabisulphite), dilauryl thiodipropionate, dimyristyl thiodipropionate, distearyl thiodipropionate, tocopherol, D-α

    -tocopherol, tocopheryl acetate, d-α

    -tocopheryl acetate, d,l-α

    -tocopheryl acetate, sorbitol glyceryl tricitrate, and sucrose octaacetate, the cosmetic coat, when present, covers at least a portion of the tablet composition, and dissolves within 30 minutes after contact with aqueous media,wherein the tablet composition does not provide immediate release of the opioid even after being subjected to physical tampering selected from crushing, grinding, grating, cutting, or crisping, andwherein the tablet composition exhibits a viscosity of at least 170 mPa·

    s when measured by Viscosity Test #2, or a viscosity of at least 46 Pa·

    s when measured by Viscosity Test #1.
