Title: Sustained-release liposomal anesthetic compositions
Inventor: KIM SINIL
IPC: A61K31/167
Filed: 1998-09-18
Abstract: The invention provides a method for obtaining local anesthetics encapsulated in liposomes, such as multivesicular liposomes, with high encapsulation efficiency and slow release  in vivo.  When the encapsulated anesthetic is administered as a single intracutaneous dose, the duration of anesthesia and half-life of the drug at the local injection site is increased as compared to injection of unencapsulated anesthetic. The maximum tolerated dose of the encapsulated anesthetic is also markedly increased in the liposomal formulation over injection of unencapsulated anesthetic. These results show that the liposomal formulation of local anesthetic is useful for sustained local infiltration and nerve block anesthesia.

Abstract: Process to produce compressed air and at least one other gas separated from air in an air treatment device (S), by generating first and second air flows under pressure intended respectively for the supply of air and gas. Some of the second flow is used to supply compressed air during a temporary mode of operation. Installation supplying compressed air and a gas to a distribution system. When operating in the temporary mode, the gas is supplied at least partially from a reservoir and the whole of the second flow is supplied as compressed air. The pressure of the second flow can be controlled and the two flows are at the same pressure. The second flow is normally at a higher pressure that the first and is changed during operation in the temporary mode. The air separator can operate temporarily at a reduced rate. The gas is nitrogen, oxygen or dry air. At least some of the compressed air and some of the gas are consumed in the same unit. The system for supplying compressed air (LA) is connected to a source of air under pressure (CO2,CO3) and the system for producing and distributing a gas separated from air (LG) is connected to a second source of air under pressure (CO1). The second source can be connected to the air supply system (LA) at least temporarily via valves (V,D). One valve (V) isolates the two systems from each other. The isolation valve is sensitive to a parameter of the outlet gas, such as the flow of gas produced. The system also contains a reservoir (R) and a system for controlling the air flow supplied by the sources. At least one of the sources of air under pressure is a compressor. The system includes a separation unit (S) using adsorption, permeation or cryogenic distillation.
