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. 
Now remains tapering off prednisone and other medications: Omeprazole to reduce acid in the stomach, low dosage aspirin as a blood thinner and Fosamax (once weekly) to prevent bone marrow damage. I was told to eat lots of fibre, eat fruit, drink milk. Any side-effect issues were not a problem and could be dealt with. The tonne of weight I've put on? The moon face? Just for the duration. Don't let it bother you. Blame everything on Prednisone. Of course all this was a challenge to tolerance: I hadn't seen a doctor in 20 or more years (thought they were there to kill you), never had any drugs other than the occasional paracetemol, fit and healthy, (I will be 75 in a couple of months' and play competitive petanque three times a week) and suddenly I was drowning in them! But I knew it was par for the course. Grin and bear it, it will all go away in time.
