    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.

  • Patent number: 6933380
    Abstract: The present invention provides low-residual-solvent containing excipients with residual solvent less than <3000 ppm. Most of the excipients are required to first be modified to become more water absorbing such as by attaching a water absorbing radical, e.g., (—CH2COONa) to the carbinol groups (—CH2OH) of the excipients to form a —CH2—O—CH2COONa linkage. The linkage of the water-absorbing groups to e excipients improves the water absorbing property of the excipients, which facilitates the replacing residual solvent with water. The residual solvent can be extracted from the excipient by way of mixing with a solvent/water solution containing (1) about 75-95% (v/v) isopropanol and about 5-25% water (v/v); (2) about 65-95% acetone and about 5-35% water; and (3) about 60-85% methanol and about 15-40% water.

  • Patent number: 6750249
    Abstract: The present invention relates to an oral preparation of esculetin with controlled release. The oral preparation of esculetin with controlled release of the present invention comprises a gel-forming polymer base, preferably hydroxypropylmethylcellulose. The preparation may be coated with an enteric polymer base such as hydroxypropylmethylcellulose acetate succinate to thereby enhance solubility in the intestines. When orally administered, the preparation can continuously release esculetin. Thus, the administration frequency and dose can be reduced and a therapeutic effect on arthropathy can be established.

  • Patent number: 6680069
    Abstract: Processes for manufacturing a low-substituted hydroxypropyl cellulose are described that include dipping pulp into an alkaline solution to prepare an alkali cellulose, reacting the alkali cellulose with a hydroxypropylating agent to yield a product in a complete dissolution state, dissolving completely the product in an aqueous medium to provide a product in a complete dissolution state, neutralizing with an acid to yield a precipitate, washing, drying, and pulverizing to yield a powder having a volume-average particle diameter of less than 25 microns which is determined by a dry laser diffraction method, a loose bulk density of 0.29 g/ml or more and less than 0.40 g/ml, and a tapped bulk density of 0.55 g/ml or more. Low-substituted hydroxypropyl celluloses are also described.
