Yes, looks like mixed-case words...
any solution?
Don't use mixed case words.
Sorry. I agree that this is a real PITA, especially with the advent of tall man text (e.g. predniSONE, or my personal fave GOlytely) which are inserted automatically by the prescription writer and cannot be corrected. In your example you could try "MIP s" or "PIP s" as a work around.
