An improvement is provided in a system comprising a pressure vessel and a sprayable mixture contained therein under pressure. The mixture consists essentially of a water-in-oil type emulsion containing the active ingredients to be sprayed, the continuous phase of which emulsion consists of organic solvent containing a propellant which is liquid under pressure. The improvement resides in the fact that the continuous phase of the said emulsion consists essentially of dimethoxymethane.

A three-phase aerosol spray disinfectant-deodorant combining the simultaneous use of a complexing polymer which has a detoxifying effect with respect to a phenolic-type germicidal agent and a surface anesthetic which desensitizes the mucous membrane when the spray composition is either inhaled or deposited on the skin.

This invention is concerned with a non-stinging wound dressing. This wound dressing is characterized by plastics dissolved in a solvent system of stinging and non-stinging solvent, the combination of which provides a non-stinging solvent system with sufficient polarity to dissolve the plastic. This wound dressing is preferrably applied to wounds as an aerosol spray dressing containing bacteriostatic agents.

A circuit interrupter, such as a vacuum switch, comprises a pair of relatively movable contacts, at least one of which is a relatively flat disc made of high-cathode drop material, such as molybdenum and having one or more spiral slots extending inwardly from the periphery of the contact filled with solid low-cathode drop material, such as antimony to cause rotation of an arc between said contacts and to facilitate movement of the arc terminal as the arc rotates.

Administration of a catecholamine by a novel intranasal delivery system provides prolonged blood levels of the drug.

An air deodorizer, and a method for deodorizing rooms therewith, utilizing an aerosol of a solution containing from 2-25% by weight of non-toxic, non-oxidizing, deodorizing agent, said solution constituting liquid droplets having a weight average droplet size of less than 50 microns, more than 90% of said droplets having a size, by count, of less than 10 microns.

The invention relates to a new process for producing powdered preparations for inhalation comprising a substance having a smaller particle size distribution and a substance having a larger particle size distribution, wherein a substance having a smaller particle size distribution and a substance having a larger particle size distribution are continuously metered into a suitable mixing container such that the quotient N of the delivery speed for the metering of the substance having the smaller pa...

A process for the preparation of aqueous suspensions of sterile micronized drug particles, in particular corticosteroid, to be administered by inhalation, which produces homogenous dispersions of particles characterized by optimal size and size distribution is disclosed. The process is carried out by using a turboemulsifier equipped with a high-power turbine and connected to a loading hopper.

The present invention relates to novel pharmaceutical aerosol formulations comprising: (A) a therapeutic agent in the form of particles coated by at least one coating excipient and at least one surfactant, in suspension in (B) a liquefied propellant gas for the administration of therapeutic agents particularly by the pulmonary route and to process for preparing these formulations. It also relates to novel particles suitable for use in such formulations.

New medicament aerosol formulation based on fusafungine comprising excipient which is either dimethyl isosorbide or preferably, isopropyl myristate, and using as propellant 1,1,1,2-tetrafluoroethane.
