Filed:

Dec 16, 2003

Appl. No.:

10/537042

Inventors:

Stephan Claude De La Veaux - Wilmington DE, US
Lu Zhang - Newark DE, US

Assignee:

E. I. du Pont de Nemours and Company - Wilmington DE

International Classification:

B01J 12/00
C09C 1/00
C01G 23/047

US Classification:

422129, 422150, 422151, 422158, 423612

Abstract:

The present invention provides a method and apparatus for the controlled synthesis of nanoparticles using a high temperature process. The reactor chamber includes a high temperature gas heated by means such as a plasma torch, and a reaction chamber. The homogenizer includes a region between the reactant inlets and the plasma (the spacer zone) to ensure that feeds from the reactant inlets are downstream of the recirculation zone induced by the high temperature gas. It also includes a region downstream of the reactant inlets that provides a nearly I dimensional (varying only in the axial direction) flow and concentration profile in the reaction zone to produce nanoparticles with narrow size distribution.

Abstract:

The present disclosure provides improved film based pharmaceutical products containing uniformly distributed drug or active agent particles (e.g., to achieve improved/excellent dissolution control including enhancing dissolution and bioavailability and/or product uniformity). More particularly, the present disclosure provides improved systems/methods for fabricating film based pharmaceutical products by utilizing higher surface modified micronized drug or active agent powders and film forming precursors and drying methods that accomplish improved/efficient drying and provide improved/excellent content uniformity of active pharmaceutical agents in the fabricated film based pharmaceutical products. In exemplary embodiments, the present disclosure provides for an easier means of directly incorporating dry micronized poorly water-soluble drugs or active agent particles (e.g., fenofibrate (“FNB”)) into films. The present disclosure demonstrates some advantages of direct incorporation of surface modified-micronized poorly water-soluble drug or active agent powders in film manufacturing.

International Classification:

G06Q 10/06
G06Q 10/08

Abstract:

In some embodiments, apparatuses and methods are provided herein useful to evaluate shipping packaging used at a distribution facility. Some embodiments provide a system to evaluate packaging, comprising: an evaluation control circuit and memory storing computer instructions executed by the control circuit causing the control circuit to: for each of multiple different distribution facilities: identify a fixed number of different shipping package sizes to be available; identify multiple different potential packaging combinations; evaluate each of the multiple potential packaging combinations for each of thousands of historic order shipments; obtain a utilization rate of each of the multiple packaging combinations; identify potential packaging combinations that satisfy a utilization threshold, and identify a predicted cost to acquire and utilize each of the identified potential packaging combinations; and select a first potential packaging combination satisfying the utilization threshold and having a lowest predicted utilization cost.
