  • Patent number: 8133506
    Abstract: The present invention is directed to pharmaceutical compositions, and methods of making such compositions, wherein the compositions comprise a plurality of TPR and RR particles, wherein: the TPR particles each comprise a core coated with a TPR layer; the core comprises a weakly basic, poorly soluble drug and a pharmaceutically acceptable organic acid separated from each other by an SR layer; the RR particles each comprise the weakly basic, poorly soluble drug, and release at least about 80 wt. % of the weakly basic, poorly soluble drug in about 5 minutes when dissolution tested using United States Pharmacopoeia (USP) dissolution methodology (Apparatus 2—paddles@50 RPM and a two-stage dissolution medium at 37° C. (first 2 hours in 0.1N HCl followed by testing in a buffer at pH 6.8).

  • Publication number: 20080317846
    Abstract: A unit dosage form, such as a capsule or the like, for delivering drugs into the body in a circadian release fashion comprising one or more populations of drug-containing particles (beads, pellets, granules, etc.) is disclosed. Each bead population exhibits a pre-designed rapid or sustained release profile with or without a predetermined lag time of 3 to 5 hours. Such a circadian rhythm release drug delivery system is designed to provide a plasma concentration-time profile, which varies according to physiological need at different times during the dosing period, i.e., mimicking the circadian rhythm and severity/manifestation of gastric acid secretion (and/or midnight gerd), predicted based on pharmaco-kinetic and pharmaco-dynamic considerations and in vitro/in vivo correlations.
