  • Publication number: 20080279937
    Abstract: A unit dosage form, such as a tablet for delivering potassium into the body in a controlled release fashion, comprises of a multiplicity of microencapsulated potassium chloride crystals, which are further coated with a plasticized polymer to improve compressibility of the microcapsules. The compressible microcapsules are blended with a compression aid, such as microcrystalline cellulose and a glidant, such as colloidal silicon dioxide, to form controlled release potassium chloride tablets. The tablets may optionally include other excipients such as surfactants and disintegrants. The tablets thus produced exhibit not only high crushing strength and low friability but also release potassium in humans in a desired controlled release fashion similar to commercially available potassium chloride tablets.

  • Publication number: 20060269607
    Abstract: A unit dosage form, such as a capsule or the like for delivering drugs into the body in a circadian release fashion, is comprising of one or more populations of propranolol-containing particles (beads, pellets, granules, etc.). 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 cardiovascular drug delivery system is designed to provide a plasma concentration-time profile, which varies according to physiological need during the day, i.e., mimicking the circadian rhythm and severity/manifestation of a cardiovascular disease, predicted based on pharmaco-kinetic and pharmaco-dynamic considerations and in vitro/in vivo correlations.

  • Publication number: 20060246134
    Abstract: A unit multiparticulate dosage form for delivering one or more basic, active pharmaceutical ingredients into the body in need of such medications to achieve target PK (pharmacokinetics) profiles is described. The dosage form comprises one or more multicoated drug particles (beads, pellets, mini-/micro-tablets) having a barrier coating and a lag-time coating. Each Timed Pulsatile Release (TPR) bead population exhibits pre-determined lag-time followed by differing release characteristics. The composition and thickness of the barrier coating, composition and thickness of the lag-time coating, ratio of IR beads to one or more TPR bead populations and total dose may be varied depending on the alkalinity, pH-dependent solubility and elimination half-life of the active ingredients to achieve target PK profiles (suitable for a once or twice daily dosing regimen) in patients in need of such medications.

  • Publication number: 20060078614
    Abstract: There is provided a method for preparing an orally disintegrating tablet (ODT) composition comprising microparticles of one or more taste-masked active pharmaceutical ingredient(s), rapidly-dispersing microgranules, and other optional, pharmaceutically acceptable excipients wherein the ODT disintegrates on contact with saliva in the buccal cavity in about 60 seconds forming a smooth, easy-to-swallow suspension. Furthermore, the microparticles (crystals, granules, beads or pellets containing the active) applied with a taste-masking membrane comprising a combination of water-insoluble and gastrosoluble polymers release not less than about 60% of the dose is in the stomach in about 30 minutes, thus maximizing the probability of achieving bioequivalence to the reference IR product having rapid onset of action (short Tmax).

  • Publication number: 20050118268
    Abstract: A pharmaceutical dosage form such as a capsule capable of delivering therapeutic agents into the body in a time-controlled or position-controlled pulsatile release fashion, is composed of a multitude of multicoated particulates (beads, pellets, granules, etc.) made of one or more populations of beads. Each of these beads except an immediate release bead has at least two coated membrane barriers. One of the membrane barriers is composed of an enteric polymer while the second membrane barrier is composed of a mixture of water insoluble polymer and an enteric polymer. The composition and the thickness of the polymeric membrane barriers determine the lag time and duration of drug release from each of the bead populations. Optionally, an organic acid containing intermediate membrane may be applied for further modifying the lag time and/or the duration of drug release.
