Supervised exercise-based rehabilitation for people with intermittent claudication-Study protocol for a Danish implementation process (StRiDE).

Introduction: Intermittent claudication is a peripheral artery disease caused by arteriosclerosis. People with intermittent claudication experience leg cramping during walking, with relief of symptoms during rest. Evidence shows that by participating in supervised exercise therapy and smoking cessation programs, people with intermittent claudication can reduce those symptoms and improve health-related quality of life and maximal walking distance while minimizing the need for an operation.

Metered-dose inhalers, I: Drug content and particle size distribution of beclomethasone dipropionate.

Four commercially available beclomethasone metered dose inhalers were analyzed for both spray content uniformity and particle size. The drug contents of primed and unprimed sprays collected at the beginning of the lifetime of the canister were not significantly different from those collected throughout the experiment. Particle size analysis of the four products using the Andersen Cascade Impactor Mark II showed that the distribution profiles were not identical.
