Qvar is absorbed more than Clenil and so more is absorbed. I think it is something to do with the particle size.
1. Clenil Modulite (Trinity-Chiesi Pharmaceuticals Limited) should be prescribed at the same dose as the currently available CFC-containing beclometasone dipropionate pMDIs.
2. Qvar (Ivax Pharmaceuticals Limited) has a 2 to 2.5 fold greater potency than the currently available CFC-containing beclometasone dipropionate pMDIs and therefore should be prescribed at a lower dose than the currently available CFC-containing beclometasone dipropionate pMDIs. Further information is available in the Summary of Product Characteristics.

SLH has covered most things - Qvar does have smaller particle sizes so can not only get into the lungs easier but is distributed throughout the small airways more effectively. The inhaler has an ethanol carrier which helps this to happen. Qvar has a lung deposition of about 51% which compares to others of about 25%.
This all increases the amount of drug that gets into the lungs and therefore you need less to do the job!
