Problems solved by technology

These delivery systems can be affected by adherence of medicament particles to and "sticking" of these particles to tank walls or other surfaces within the dispenser device
This can lead to agglomeration affecting the dosage of the agent
The second problem is due to the autocatalytic degradation of some agents through contact with certain materials, especially metal oxides such as alumina and magnesia and other reactions between components and agents such as corrosion
Additionally, some coatings do not perform optimally for a number of reasons

Embodiment Construction

[0042] figure 1 Depicted is a pressurized dispenser device substantially as shown at 10 comprising a housing 12 containing an arrangement 14 containing a pressurized medicament. The housing 12 comprises an open-ended cylindrical portion 12a housing an arrangement 14 containing a pressurized medicament and an open-ended channel 12b serving as an interface. The housing 12 further comprises an inner wall 12c supporting a socket 12d having a passageway 12e accommodating the valve stem of the arrangement containing the pressurized medicament. Passage 12e communicates with opening 12f, which in turn communicates with an outlet passage defined by open-ended passage 12b. The inner wall 12c has formed therein a number of apertures 12g which allow air to flow from the upper region of the housing into the open-ended passage 12b.

[0043] The structure and operation of the pressurized medicament container arrangement 14 will now be described in detail. Arrangement 14 includes a can 16 ...

Abstract

According to the invention there is provided a dispenser device for dispensing a medicament, the device including at least one metallic component having at least one non-metallic surface which comes into contact with the medicament during storage or use of the device, in which said non-metallic surface has an interface with the underlying metallic component which substantially comprises metal-fluoride and / or metal carbide moieties.

Description

technical field [0001] The present invention relates to a dispenser device for dispensing a medicament, a method of manufacturing a dispenser device for dispensing a medicament, and a method of processing components of said dispenser device, with particular but by no means exclusive reference to a pressurized dispenser device. Background technique [0002] It is well known to dispense medicaments to patients by inhalation using pressurized dispenser devices which dispense medicaments with a carrier fluid. The agent may be presented as a particulate suspension or solution, or even a combination of the two. Such devices are often also referred to as pressurized metered dose inhalers (pMDIs) and are very commonly used in the treatment of asthma and chronic obstructive pulmonary disease (COPD). [0003] Problems with such dispenser devices include adsorption, binding or degradation of active medicament on the interior surfaces of the device, and corrosion of delivery device com...
