Title: Methods for the controlled delivery of pharmacologically active compounds
Inventor: MURTHY YERRAMILLI V S N
IPC: A61K47/22
Filed: 2004-04-15
Abstract: The present invention provides compositions and methods for extending the release times and lowering the toxicity of pharmacologically active compounds.  The compounds comprise a salt of the pharmacologically active compound with a lipophilic counterion and a pharmaceutically acceptable water soluble solvent combined together to form an injectable composition. The lipophilic counterion may be a saturated or unsaturated C8-C22 fatty acid, and preferably may be a saturated or unsaturated C10-C18 fatty acid. The compounds precipitate in aqueous environments. When injected into a mammal, at least a portion of the composition precipitates and releases the active compound over time. Thus, the composition forms a slowly releasing drug depot of the active compound in the mammal. Therefore, the present invention enables one to provide a controlled dose administration of the active compound for a period of up to 15 days or even longer. Many compounds can be administered according to the present invention including, but not limited to, tilmicosin, oxytetracycline, metoprolol, fluoxetine, roxithromycin, and turbinafine.

Abstract: An equipment inspecting and evaluating system can be used to inspect and evaluate steam traps by detecting a level of vibrations of each trap and the surface temperature of the housing of that trap. The detected vibration level and temperature are used to determine whether or not steam is leaking through that trap and to what extent steam leakage is. An equipment management system is connected to the inspection and evaluation system by a data transmission cable and receives inspection data of the traps from the inspection and evaluation system. The management system analyzes the received inspection data for computing the number of defective traps, the ratio of defective traps to the entire traps, the loss caused by steam leakage, etc.
