    摘要: The invention relates to a device for determining the dissolution time of medication in pressed form, like tablets and capsules, (especially to DAB 10, 3rd Supplement 1994, or the European Pharmacopoeia or USP [USA]), consisting of a frame (1) with a central column (7) and a base plate (3, 10) having a plurality of holes (5, 5', 11) covered from below by a mesh (4). Test tubes (6, 6') are arranged upright in said holes inside the frame (1). A disk (8, 15) can be movably inserted into said test tubes to weight the individual pressed medication. An electric coil (12) is disposed around each hole (11) and on and/or in the base plate (10), wherein the electric coil forms part of an electrical oscillation circuit (17). A conductor loop (16) is disposed on and/or in the disk (15) for damping the electrical oscillation circuit (17) depending on distance. The electric coil (12) and the conductor loop (16) together are connected to an electric supply and evaluation device (20, 23) to generate oscillations and evaluate the measurement results.

    摘要: A diffusion test apparatus (2), used to test diffusion of a drug within a vehicle through a test membrane (8), includes a receiver assembly (6) and a donor assembly (4) secured to one another. The receiver assembly includes a number of open-top receiver receptacles (26) arranged in a chosen pattern along its face (12). Similarly, the donor assembly includes a number of open-top donor receptacles (38) arranged along its face (10) in a mirror image of the chosen pattern. The test membrane is captured between the receiver and donor faces. The drug diffuses through the test membrane and into the receiver liquid (53) during an incubation period (62). Samples (66) of the receiver liquid are preferably automatically transferred to a conventional microtiter plate (70) using a programmed liquid transfer system for assay by a scintillation counter (76).

    摘要: A method and apparatus for optimally performing dissolution testing of pharmaceutical dosage forms, agricultural products, and components of industrial products wherein the method uses dissolution profiles from a known drug dosage form, or product, as reference data for a predictive process; and the apparatus is organized to carry out the method via both closed loop and open loop operating modes under the control of a central processor. An illustrative embodiment teaches the serial usage of the two operating modes in a single flow-through dissolution cell configuration to optimally predict the time course of in vivo bioavailability from in vitro dissolution measurements, while an alternate embodiment teaches the use of a plurality of dissolution cells and the simultaneous use of the closed and open loop operating modes to implement an Internal Standard capability. Additionally, an optimally adaptive capability is provided in the dissolution testing process via a random input modeling mode of operation.

    摘要: THIS INVENTION PROVIDES AN IMPROVEMENT IN A TABLET DISINTEGRATING APPARATUS, BY PROVIDING A PLURALITY OF OPPOSED SPACED ELECTRODES AT THE BASE OF THE TABLET CONTAINING TUBES. IN THE OPERATION OF THE APPARATUS AN ELECTRIC FIELD IS SET UP BETWEEN THE ELECTRODES. THE PRESENCE OF A TABLET DISTURBS THIS ELECTRIC FIELD, WHICH DISTURBANCE ACTUATES A RECORDING DEVICE SUCH AS A TIMER. THE CONVENTIONAL RECIPROCATING VERTICAL MOTION OF THE APPARTUS (IN AN AQUEOUS BATH) CAUSES THE TABLET TO DISINTEGRATE. AT THE END POINT OF THE TABLET DISINTEGRATION, THE UNDISTURBED FLOW OF CURRENT BETWEEN THE ELECTRODES STOPS THE RECORDING DEVICE, NOTING THE INTERVAL OF TIME FOR TABLET DISINTEGRATING

    摘要: A basket stirrer for testing the dissolution rate of solid pharmaceutical preparations such as tablets and capsules. Passage means is provided through the drive plug which forms a closure at the upper end of the generally cylindrical screen basket to break the air or fluid lock which otherwise introduces errors in the routine laboratory use of this type of equipment by preventing proper fluid drainage from the basket when it is raised out of the testing solution at the end of a test, or proper circulation of the fluid through the basket during the test.

    摘要: The invention provides a system and method for dissolution testing. The system includes multiple dissolution vessels and a dose carrier positioned above the dissolution vessels. The dose carrier holds multiple removable carousels that receive individual doses for dissolution tested. Carousels that receive tablets or sinkers typically have a first configuration, while carousels that receive baskets typically have a second configuration. The two different configurations of carousels are interchangeable on the same dose ring. The system further includes a drive head positioned above the dose carrier, the drive head having a basket arbor and a mixing paddle removably and interchangeably attached. A pipettor integral with the system transfers sample aliquots having volumes in the range of 50 μl to 1 ml from the dissolution vessels to wells of an external receptacle.

    摘要: A dissolution and precipitation system includes an array of reactors. Each reactor has a mother well and a daughter well having a volume between about one microliter and one milliliter. A fluid transfer system is operable to transfer fluid between the mother well and daughter well and purify the fluid that is transferred to the daughter well from the mother well. A method of testing a plurality of samples includes dissolving a plurality of first solids in each of the mother wells to form a plurality of first solutions in the mother wells. The first solutions are purified in the reactors. The first solutions are distributed from the mother wells to one or more daughter wells. A plurality of second solids are precipitated in the daughter wells and the second solids are analyzed.
