Tolerability of high cumulative doses of the HFA modulite beclomethasone dipropionate/formoterol combination inhaler in asthmatic patients

High doses of BDP/formoterol did not significantly reduce serum potassium, while formoterol alone did to a greater extent. The BDP/formoterol combination was well tolerated, and exhibited a safety profile generally similar to formoterol alone when administered in high doses to stable asthmatic patients.
