Abstract: The present invention is directed to improved compositions and methods for preparing orally disintegrating tablets (ODTs). In one aspect of the present invention, the ODT further contains at least one active pharmaceutical ingredient (API). In another aspect of the present invention, the ODT contains a high load of at least one API. Specifically, the ODTs described in this invention containing a high load of API can accommodate up to about 70% w/w of active pharmaceutical ingredient in a unit dosage, while exhibiting the desirable attributes of fast disintegration time, acceptable hardness and friability for push through blister and bottle packages, and acceptable mouth feel.

Abstract: The present invention is directed to control of medical fluid injection systems. For instance, in some embodiments, an injection protocol may be initiated, and an actual flow rate of the medical fluid utilized in the injection protocol may be adjusted based, at least in part, on an inherent system elasticity of the injection system.
Abstract: The filling of a syringe can be performed at a faster rate using a filling sequence which expels air from the fill tube before filling the syringe. A similar method is used when changing contrast containers during a filling sequence to ensure that all the air is expelled from the fill tube before filling resumes with the new contrast container. Additionally, by including a contrast container holder that is affixed to an injector head and holds the container near the syringe tip, the filling sequence can be accomplished without requiring the operator to hold the contrast container during the sequence.

Abstract: An apparatus and method for separating at least one narcotic alkaloid that includes loading a stationary phase media into a high performance preparative liquid chromatography column, feeding a crude narcotic alkaloid solution into the chromatographic column, applying a mobile phase to the chromatographic column, and recovering a narcotic alkaloid eluate from the chromatographic column. The narcotic eluates arc collected and treated separately from each other. Each separated alkaloid, however, has sufficient recovery and purity.
Abstract: The present invention provides a synthetic process for the N-demethylation of N-methyl morphinans. In particular, the invention provides improved synthetic methods for the preparation of N-demethylated morphinan compounds that may be employed as starting materials, for example, commonly available N-methyl opiates such as oripavine and thebaine, and C(3)-protected hydroxy derivatives of oripavine.

Abstract: An organized mobile multicomponent conjugate (OMMC) and method of using to enhance binding of weakly binding compounds to a target. A lamellar structure containing at least two binding compounds is assembled under conditions in which the binding compounds self-regulate in or on the lamellar structure, forming a cooperative ensemble that is capable of binding with enhanced affinity to a complementary affinity site on a target. Each binding compound is bound to the lamellar surface, and may be connected by a linker. The OMMC may contain an effector molecule, such as a diagnostic or therapeutic agent, for administration to a patent who is then diagnosed or treated using the effector molecule.

Abstract: A powered injector that stores energy at a low rate when not in use and delivers energy at a high rate during injection. Energy may be stored in a highly responsive energy storage device, such as a capacitor, for rapid delivery of power to the injector motor. In certain embodiments, wires connecting the powered injector to a power supply may be relatively small and inexpensive because the current and voltage loads placed on the wires are relatively low.
Abstract: Cyanine and indocyanine dye compounds and bioconjugates are disclosed. The present invention includes several cyanine and indocyanine dyes, including bioconjugates of the same, with a variety of bis- and tetrakis (carboxylic acid) homologues. The compounds of the invention may be conjugated to bioactive peptides, carbohydrates, hormones, drugs, or other bioactive agents. The small size of compounds of the invention allows favorable delivery to tumor cells as compared to larger molecular weight imaging agents. Further, use of a biocompatible organic solvent such as dimethylsulfoxide may be said to assist in maintaining the fluorescence of compounds of the invention.
