摘要:
Inhalation particles incorporating, in an individual particle, a combination of a βhd 2-agonist and a glucocorticosteroid in a predetermined and constant ratio, a process for the preparation thereof and pharmaceutical compositions comprising the inhalation particles. The particles have a narrow particle size distribution and are preferably in the form of spherical crystalline particles with a rough surface. The particles are particularly useful in the treatment of asthma and other respiratory disorders.
摘要:
The present invention relates to single walled and multi-walled carbon nanotubes (CNTs), functionalized CNTs and carbon nanotube composites with controlled properties, to a method for aerosol synthesis of single walled and multi-walled carbon nanotubes, functionalized CNTs and carbon nanotube composites with controlled properties from pre-made catalyst particles and a carbon source in the presence of reagents and additives, to functional, matrix and composite materials composed thereof and structures and devices fabricated from the same in continuous or batch CNT reactors. The present invention allows all or part of the processes of synthesis of CNTs, their purification, doping, functionalization, coating, mixing and deposition to be combined in one continuous procedure and in which the catalyst synthesis, the CNT synthesis, and their functionalization, doping, coating, mixing and deposition can be separately controlled.
摘要:
Crystalline spherical inhalation particles incorporating a combination of two or more different active ingredients and a process for the preparation thereof. The particles have a narrow particle size distribution, rough surfaces and improved stability. The inhalation particles of the invention are particularly useful in the administration of a combination medicament, e.g. a combination of an anti-inflammatory agent and a bronchodilator, by inhalation in the treatment of asthma and other respiratory disorders.

摘要:
A device for delivering a powdered medicament by inhalation comprises an air inlet passage having low pressure-drop and low turbulence for stabilizing air flow before aerosolization, a dosing cup in the region of reduced air velocity to delay aerosolization, a high pressure drop throat to generate a high velocity flow, a rapidly expanding diverging passage to create a free jet of air with high turbulence and an outlet passage having large cross-sectional area to control the rate of dissipation of the free jet. The device is simple yet capable of consistently providing uniform and effective powder aerosolization and deagglomeration over a variety of patient inhalation profiles.
