  • Publication number: 20080182293
    Abstract: The present invention relates to computer-controlled high-throughput systems, computer-program products, and methods of use to prepare a large number of component combinations, at varying concentrations and identities, at the same time, and high-throughput methods to test tissue barrier transfer, such as transdermal transfer, of components in each combination. The methods of the present invention allow determination of the effects of inactive components, such as solvents, excipients, enhancers, adhesives and additives, on tissue barrier transfer of active components, such as pharmaceuticals. The invention thus encompasses the use of computer-controlled high-throughput systems, computer-program products, and methods of high-throughput testing of pharmaceutical compositions or formulations in order to determine the overall optimal composition or formulation for improved tissue transport, such as transdermal transport.

  • Publication number: 20070020662
    Abstract: The present invention relates to computer-controlled automated high-throughput systems and/or computer-program products to design, prepare, process, and analyze a large number of samples having experimental formulations each containing a compound of interest formulated with differing component combinations and varying concentrations and component identities. The computer-controlled methods of the present invention allow determination of the effects of additional or inactive components, such as excipients, carriers, enhancers, adhesives, additives, and the like, on the compound of interest, such as pharmaceuticals. The invention thus encompasses the computer systems, computer methods, and computer-program products for computer-controlled automated high-throughput testing of pharmaceutical compositions or formulations in order to determine the overall optimal composition or formulation for an intended use or purpose.

  • Publication number: 20070021929
    Abstract: Computer-controlled automated high-throughput systems can be used to design, prepare, process, screen, and analyze a large number of samples in removable sample vials each containing a compound of interest formulated with differing component combinations and varying concentrations. The computer-controlled methods of the present invention allow for a determination of the effects of additional or inactive components, such as excipients, carriers, enhancers, adhesives, additives, and the like, on the compound of interest, such as a pharmaceutical. The invention thus encompasses the computer systems, computer methods, and computer-program products for computer-controlled automated high-throughput testing of experimental formulations in order to identify experimental formulations that can be further processed. Identified experimental formulations from multiple arrays can be removed and re-arrayed together to form a new array for further processing.

  • Patent number: 6852526
    Abstract: The transdermal assay apparatus includes first, second, and third members. The first member has one or more sample surfaces, each of which is configured to receive a sample thereon. The second member defines one or more reservoirs, each of which has an opening on a surface of the second member. Each sample surface is substantially the same size as each opening. The transdermal assay apparatus also includes a magnetic clamp configured to clamp a tissue specimen between the sample surface and the opening. The magnetic clamp preferably includes a magnet having a strength that is selected based on the clamping force required between the first member and the second member. The invention also provides a method for using a transdermal assay apparatus.
