Abstract: The present invention relates to orally administered suspensions of pharmaceutical active substances of the NSAID type, particularly the antirheumatic agent Meloxicam, which are stabilized by the addition of small amounts of highly dispersed silicon dioxide using high shear forces and adding small amounts of hydrophilic polymers to form a three-dimensional siloid structure, and a process for the preparation thereof.
Abstract: The present application discloses a finely divided, dry powdered pharmaceutical composition which is specially adapted to be administered as an insufflate which includes the following ingredients:
(a) an pharmacologically effective amount of sICAM-1;
(b) an amount of carboxymethyl cellulose which is effective to retain sICAM-1 on the intranasal membranes;
(c) an amount of a bulking agent which is effective to provide a bulking effect without exerting a significant effect on the retention of the sICAM-1 on the nasal passages.

Abstract: Apparatus and process for non-destructively testing a fluid-filled container for leaktightness, the process comprising:
(a) subjecting the fluid-filled container to a vacuum or near vacuum environment;
(b) utilizing electrical equipment to form an electrical discharge in the vacuum or near vacuum environment sufficient to stimulate spectral light emissions from volatile fluid-filled container contents present in the vacuum or near vacuum environment;
(c) detecting the spectral light emissions from the volatile fluid-filled container contents produced in step (b); and
(d) evaluating the spectral light emissions detected in step (c) to determine the amount of volatile fluid-filled container contents present in the vacuum or near vacuum environment by comparing: (i) the measured brightness level of the spectral light emissions obtained from step (c), to (ii) a base brightness level obtained by measuring the brightness level of the spectral emissions due to the presence of residual gas or air molecules in the

Abstract: A method for the preparation of oxycodone, and salts thereof, from codeine comprising oxidation of codeine to codeinone, formation of an dienolsilyl ether congener of codeinone in strong amine base, oxidation of the dienolsilyl ether congener using peracetic acid, and hydrogenation of the resulting 14-hydroxycodeinone product.
Abstract: For medical fluids, two-part containers are used which consist of an inner container and an outer container which is impenetrable to diffusion. The inner container collapses when the fluid is removed.
For the purposes of pressure compensation between the gaseous space, disposed between the inner- and outer containers, and the surroundings of the two-part container, a pressure compensation device is required by means of which at the same time the loss of fluid through diffusion from the collapsible inner container is kept as little as possible. To that end, at least one channel is used which communicates the gas-filled intermediate space with the surroundings of the two-part container. The time constant for compensation of a pressure differential of a few millibars is within the region of quite a few hours. It is obtained by selecting the length of the channel and channel cross-section.
