  • Patent number: 6758099
    Abstract: The present invention relates to high-throughput systems and methods 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 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: 20040106098
    Abstract: Methods and systems are disclosed that can be used for the automated preparation and analysis of mixtures comprising a compound-of-interest (e.g., the active ingredient of a pharmaceutical composition) and one or more excipients. Specific embodiments of the invention are particularly suited for the precise preparation and screening of small amounts of excipients, compounds-of-interest, and mixtures thereof. The invention is also well suited for the preparation and screening of small amounts of mixtures comprising high concentrations of compounds-of-interest.

  • Publication number: 20040092428
    Abstract: The invention concerns excipients or combinations thereof suitable for preparing an oral formulation containing a pharmaceutical agent. More particularly, the invention is directed to stable, efficacious and bioavailable oral pharmaceutical formulations comprising paclitaxel, derivatives of paclitaxel and pharmaceutically acceptable salts thereof. The formulations of the invention increase bioavailability of paclitaxel when dissolved in the gastrointestinal system. The formulations of the invention are useful for administering paclitaxel, its derivatives, or pharmaceutically acceptable salts of such derivatives to patients in need thereof. The formulations of the invention are particularly suitable for oral administration to mammals including humans.

  • Publication number: 20030068614
    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.
