when the pill turns to a dust when you puncture it then it is a help for my copd.but 15-25 percent of the pills do not work.
Pills are made by compressing the active ingredient & various other components such as the lubricant, binder, starch, masking additives, if coating is required, such as sugar coating or entric coating or film coating, they could be sustained release etc. & when crushed could lose efficacy & effectiveness, perhaps that is the reason pills do not work when crushed for inhalation, hope have been able to briefly explain & it helps? However the pharmacist could be the best person to give you a professional explanation.
I use advair, i took apart an expired advair dispenser, what i found was very tiny blister packs of powdered medication, in the case of advair, when the lever is pushed, it breaks the blister of the powder and you inhale the very fine powder into your lungs, now i have read that sometimes the device does not break the blisters all of the time, so i guess other meds can malfunction too, i would talk to a pharmacist or your Dr. just to make sure you are using it properly, & if you are and that is happening, see about a replacement.
