A dry powder delivery device may be configured to provide micronized dry powder particles to airways of a user. The device may include a cylindrical container delimiting a chamber containing at least one magnetically-responsive object, a motor external to said chamber, a magnet external to the chamber and rotatably coupled with the motor, and an outflow member configured to direct airflow to a user. The magnetically-responsive object may be coated with micronized dry powder particles, and the motor may be operable to rotate the magnet about an axis. Rotation of the magnet creates a magnetic field that causes the magnetically-responsive object to move in response to the magnetic field and collide with a side wall of the container to deaggregate the dry powder particles and aerosolize the dry powder in the chamber.

Devices and methods for nasal administration of a pharmaceutical composition. In certain embodiments, the devices comprises a reservoir, a conduit in fluid communication with the reservoir, and an anatomic positioning device configured to position the conduit in a nasal cavity of a user. Particular embodiments include an actuator configured to transfer the pharmaceutical composition from the reservoir to the conduit and emit the pharmaceutical composition from the conduit.

Compositions and devices to administer pharmaceutical compositions nasally

The present disclosure provides pharmaceutical compositions of niclosamide that may be administered either orally or by inhalation. These compositions may allow the achievement of a therapeutically effective dose of niclosamide to the lungs or the gastrointestinal tract. These compositions may be used to treat one or more diseases or disorders such as a viral infection or cancer.

Pharmaceutical compositions of niclosamide

Various embodiments disclosed relate to methods and compositions for antimicrobial treatment. In various embodiments, the present invention provides a method of antimicrobial treatment. The method includes at least one of exposing at least one microbe to a magnetic field, and contacting the at least one microbe with at least one nanoparticle including iron.

Methods and compositions for antimicrobial treatment

A dry powder inhaler including a housing defining a chamber for receiving a dose of powdered medicament, an inhalation port in fluid communication with the chamber, at least one airflow inlet providing fluid communication between the chamber and an exterior of the housing, and a flutter element in the chamber and associated with a dose of powdered medicament. The flutter element has a tensioned distal end proximate the at least one airflow inlet and a free proximal end opposite to the distal end and downstream of the inlet. The flutter element is configured to vibrate in response to airflow through the chamber and aerosolize the dose of powdered medicament.

Processes for preparing micronized particles comprising a poorly water soluble bioactive agent are provided. The processes utilize a superheated aqueous phase which can serve as the continuous phase of an emulsion. The superheated aqueous phase can be used to melt poorly water soluble bioactive agents and/or matrix materials which them form molten droplets dispersed within the superheated aqueous phase. The size and size distribution of the molten droplets can be controlled using a variety of suitable methods. The molten droplets can then be cooled to form micronized particles comprising the poorly water soluble bioactive agent. If desired, the cooling rate can be selected to control the crystalline morphology of the resulting micronized particles.

Methods for fine particle manufacture

A method of method of coating powdered medical agent onto a carrier particle for use in a dry powder inhaler may include applying ultrasonic energy to agglomerated powdered medical agent to deaggregate and aerosolize particles of the medical agent into particles having a desired average particle size, and coating at least one carrier particle with a desired amount of the deaggregated and aerosolized particles of the medical agent.

Methods and systems for dosing and coating inhalation powders onto carrier particles

A device for coating dry powder microparticles onto a surface may include a jet mill configured to mill dry powder particles into microparticles having a desired aerodynamic diameter and to deaggregate the microparticles, a feed hopper structured and arranged to feed dry powder particles to the jet mill, a surface configured to receive dry powder microparticles and an exit nozzle associated with the jet mill. The exit nozzle may be arranged to direct deaggregated micronized dry powder particles from the jet mill to the surface to be coated. The device may further include a holder structured and arranged to hold an item, wherein the item includes the surface. In some aspects of the device, the item may be a film.

Apparatuses and methods for microparticle dry coating of surfaces

Disclosed are aerosol-mediated methods for synthesizing particles for biomedical and drug delivery applications. The method is based on the production of particles from sprayed polymeric micro or nano-droplets obtained by, for example, an air-jet nebulization process that is followed by gelation and/or hardening in a crosslinking fluid, non-solvent, precipitating solvent, or supercritical fluid.
