As a glucocorticoid , the lipophilic structure of prednisolone allows for easy passage through the cell membrane where it then binds to its respective glucocorticoid receptor (GCR) located in the cytoplasm. Upon binding, formation of the GC/GCR complex causes dissociation of chaperone proteins from the glucocorticoid receptor enabling the GC/GCR complex to translocate inside the nucleus. This process occurs within 20 minutes of binding. Once inside the nucleus, the homodimer GC/GCR complex binds to specific DNA binding-sites known as glucocorticoid response elements (GREs) resulting in gene expression or inhibition. Complex binding to positive GREs leads to synthesis of anti-inflammatory proteins while binding to negative GREs block the transcription of inflammatory genes. 
This confusing situation happens often, even when the
rescue and maintenance inhalers are of
different color. The root problem is lack of standardization
among inhalers, with unclear labeling to distinguish between
rescue and maintenance inhalers. A contributing cause is
lack of proper education for both the caregivers and their patients .
All too often proper instructions were not given
when the drug was first prescribed. And even when they are provided,
patients sometimes don't really understand, or they forget.
Either way, having similar inhalers for different purposes
is an invitation to error. (This was less likely to be a problem
when the drug was studied
by the drug companies; see YELLOW BOX above, under 'DPI Type 2'.)
The problem is compounded when patients are on multiple
inhalers, eg, Proventil for rescue, Advair and Spiriva for
maintenance. That's 3 separate devices with two different
purposes -- easy for the patient to get confused. (Pills and
capsules come in many colors and sizes, but they are all
swallowed the same way.) What's needed is a universal delivery
device for all inhalers, with perhaps just two colors:
red for rescue drugs and green for maintenance drugs.
Anyone with clinical interest in the inhaler problems discussed above
(Errors 1 & 2) should definitely read

3. Not checking some objective measurement of the patient's air flow obstruction.
Every patient should have a breathing test to ascertain the degree of
impairment caused by the asthma. The most frequently performed
test is 'spirometry', which takes just a few minutes and requires the
patient to exhale forcefully thru a testing device (shown below).

Thanks a lot. I am really inspired with your efforts to remove quite a lots of misconceptions about Homeopathy in general public. Many Leading Homeo drs are least interested in educating people about this. Many times i have asked my doctor ( one of the leading homeo dr in my city) and he says that it is out of jealousy people are spreading this propaganda. But my question is what is your effort in preventing this spread of false propaganda. Anyway i am really happy that, though you are always a busy person, but when approached- very mild, scientific tempered and matured person. May god give you more and more strength to spread homeopathy in a scientific spirit.
