Pharmaceutical compositions of nalbuphine and flurbiprofen have been found to exhibit unexpectedly enhanced analgesic activity by applying an analysis model which considers data characterizing the analgesic effect of both the pure components as well as the fixed dose ratio combinations. This synergism enables the use of lower doses of either or both drugs with a concomitant reduction in risk of possible side effects.
Provided herein are compositions and methods of making compositions of ibuprofen in combination with a narcotic analgesic. Specifically provided is a pharmaceutical tablet composition comprising ibuprofen; a narcotic analgesic; colloidal silicon dioxide; a filler selected from the group consisting of microcrystalline cellulose and powdered cellulose; a disintegrant selected from the group consisting of croscarmellose sodium, crospovidone, and sodium starch glycolate; a binder consisting of an akylhydroxy methylcellulose; a starch; and a lubricant. Also provided herein is a method of preparing a pharmaceutical tablet composition comprising: (a) Granulating ibuprofen, a narcotic analgesic, a first glidant, a first disintegrant, a binder, and starch to form granules wherein said granulating step comprises a wet granulation process; (b) blending the granules with extra-granular material comprised of a second glidant, a second disintegrant, a filler and starch to form a blend of granules and extra-granular material; and (c) compressing the blend into a tablet.
