Foreign body aspiration: a hazard of metered dose inhalers.

Foreign body inhalation: a danger of metered dose inhalers.

Sir, As in Dundee (Letters, October Journal, p.430), the Nottingham general practice attachment includes a student audit project. Our experience over several years is that these work best if the topic is chosen by the student. The role of the tutor is often to limit the amount of work planned and to emphasize that while the study is likely to be useful to the practice, the educational objective...

Metered-dose inhalers, dry powder inhalers, and transitions.

Since 1956, the pMDI has become the most commonly prescribed and used aerosol device in the world. While concerns about global warming have led to a worldwide ban of CFCs, new HFA-propelled pMDIs are in development, requiring an evolutionary transition in the technology. The phase-out of CFC-propelled pMDIs has stimulated the development of more efficient DPIs, but issues such as cost of device...

Metered-dose inhalers and dry powder inhalers in aerosol therapy.

Inhaled drug delivery is an important part of the armamentarium of clinicians caring for patients with pulmonary disease. An increasing variety of metered-dose inhalers and dry powder inhalers are becoming available. This has been driven by the development of new formulations and the impending ban on chlorofluorocarbon propellants. The result is a proliferation of devices, resulting in a confus...

Metered dose inhalers and spacer devices.

Easy to carry, highly effective and extremely safe, allowing accurate, consistent dose delivery, metered dose inhalers are the inhalation devices doctors and patients choose most readily the world over. Clinical response, however, may be affected by the inhalation technique used and the precise formulation in the canisters. The purpose of this review is to consider metered dose inhalers, add on...
