摘要： Dosage forms for oral administration of a methylphenidate drug are provided. The dosage forms provide a substantially immediate dose of methylphenidate upon ingestion, followed by one or more additional doses at predetermined times. By providing such a drug release profile, the dosage forms eliminate the need for a patient to carry an additional dose for ingestion during the day. The dosage forms and methods provided are useful in administering methylphenidate and pharmaceutically acceptable salts thereof, which generally require one or more doses throughout the day.

摘要： In accordance with the present invention, these and other objects are achieved by a pharmaceutical composition comprised of 1) a pharmaceutical core which is further comprised of a pharmaceutically active dose of a compound and, 2) a microencapsulating polymer which coats the pharmaceutical core and is capable of taste-masking the active compound. The polymer coating maintains its integrity, i.e., does not fracture and release active when tabletted and/or chewed, and can provide immediate release of the active compound in the stomach, or alternatively, in certain embodiments, can release the active agent in the upper intestinal tract or in sustained release fashion. Additionally, the polymeric coating compositions or the pharmaceutical core may contain diluents, fillers, bulking agents, and plasticizers. The polymeric coatings may also contain pigments and opacifiers to promote compliance and enhance the storage stability of light sensitive active agents.

摘要： In accordance with the present invention, the controlled release formulation contains coated pellets of indomethacin of only one type. The pellet releases indomethacin in both immediate and sustained release form. The immediate release indomethacin is rapidly absorbed from the stomach to provide a bolus dose of active agent. The sustained release indomethacin is gradually released over time to maintain the blood levels at effective concentrations for long periods of time.

摘要： A therapeutic preparation consisting of three groups of spheroids containing an active medicinal substance. The first group of spheroids is uncoated and rapidly disintegrates upon ingestion to release an initial dose of medicinal substance a second group of spheroids is coated with a pH sensitive coat to provide a second dose and a third group of spheroids is coated with a pH independent coat to provide a third dose. A powder blend of active medicinal substance may be substituted for the first group of uncoated spheroids.The therapeutic preparation may be utilized as a mixture of groups of spheroids in a capsule.

摘要： An opioid-antagonist oral dosage form which does not release a therapeutically effective amount of the opioid antagonist when the oral dosage form is orally administered to a human being, but whereby a physical alteration of the oral dosage form results in a release of the therapeutically effective amount of the opioid antagonist. An embodiment of the oral dosage form includes an opioid-antagonist layer coated onto a biologically inert pellet, and a non-releasing membrane coated onto the opioid-antagonist layer. Optionally, the oral dosage form can also include an opioid agonist, such that a method of preventing the abuse of an oral dosage form of an opioid agonist is provided by forming the oral dosage form including an opioid agonist and an opioid antagonist.

摘要： A dosage formulation for once daily administration prior to sleeping is described that provides an initial delay in pharmaceutical release followed by controlled release of the pharmaceutical. There is also provided a method for preparing a time specific delayed, controlled release formulation of dosage, which method includes coating a single pellet with at least one dosage layer, which is coated by at least one seal coat and at least one outer rate controlling layer of a water soluble polymer coat. The dosage formulation of this invention provides a substantially drug free interval of about 0 to 5 hours followed by a drug delivery interval at a rate permitting bioavailability thereof for up to about 24 hours following oral administration. A method of using the formulations of the present invention for the treatment of early morning pathologies, including atrial fibrillation, is also described.
