  • Patent number: 8545881
    Abstract: A tablet that rapidly disintegrates in the oral cavity comprising a compressed blend of rapidly dispersing microgranules prepared by granulating a sugar alcohol or a saccharide or a mixture thereof having an average particle size less than about 30 microns and a disintegrant, and a taste-masked microcapsule containing at least one drug, the microcapsule being prepared by granulating a pharmaceutically acceptable formulation comprising at least one drug in a therapeutically effective amount and at least one polymeric binder that improves resilience of the microgranules, wet milling the granulated mass, and microencapsulating the milled granules to provide microcapsules.

  • Publication number: 20130209567
    Abstract: A unit dosage form, such as a capsule or the like, for delivering a skeletal muscle relaxant, such as cyclobenzaprine hydrochloride, into the body in an extended or sustained release fashion comprising one or more populations of drug-containing particles (beads, pellets, granules, etc.) is disclosed. At least one bead population exhibits a pre-designed sustained release profile. Such a drug delivery system is designed for once—daily oral administration to maintain an adequate plasma concentration—time profile, thereby providing relief of muscle spasm associated with painful musculoskeletal conditions over a 24 hour period.

  • Patent number: 8367111
    Abstract: A unit dosage form, such as a capsule or the like for delivering drugs into the body in a sustained release fashion similar to that produced by INDERAL® LA indicated for the treatment of cardiovascular diseases, comprises two populations of propranolol-containing particles (beads, pellets, granules, etc.). Each bead population exhibits a pre-designed rapid release profile (i.e., substantially complete release within 60 minutes) or sustained release profile over a period of 24 hours. Such a cardiovascular drug delivery system is designed by combining immediate release (IR) beads and sustained release (SR) beads. SR beads may be obtained by membrane coating IR beads with a water-insoluble polymer such as ethylcellulose or a mixture of a water insoluble polymer and a water-soluble polymer such as hydroxypropylcellulose at a ratio of from about 65/35 to 95/5.

  • Publication number: 20120282335
    Abstract: This invention relates to rapidly dispersing microgranules comprising at least one sugar alcohol or saccharide, at least one super disintegrant, and a pharmaceutically acceptable additive with multi-functionality (e.g., starch acting as a binder, disintegrant, diluent/filler, glidant, etc) at a low level, which can be formed by not only eliminating a wet milling step but also avoiding an extensive dry milling step.

  • Publication number: 20120128771
    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.
