@ Marianne and Werner:
Thanks for your answers! At the time, when I wrote my "revocation" for my question, there was no reply, so please forgive me the "don´t waste your time"-stuff. I just wanted to prevent people to bother with my basic grammar problem/question, if I could solve it by myselve after all by not being to lazy to look in the web ;-).
However, now I´m quite glad, that I got your answers, because e.g. the hint with the:
"Added to which, "applied" is used only for topical medications - if the comedication was given orally, IV or IM , then you need to say "administered"/"used"/"given" /"taken", as appropriate."
I wasn´t aware of that difference "applied versus administered, etc..
In this case, "administered"/"used"/"given" /"taken", would be appropriate, thanks.
And its: "No comedication WAS given for the duration of the study ." I´ve already corrected this in the manuscript I have to deal with in the moment.
Thanks a lot one more time!
