Sedated (5)
I believe the answer is:
under
'sedated' is the definition.

This is all the clue.
(Other definitions for under that I've seen before include "Managed by" , "Dylan Thomas radio play ''.... Milk Wood''" , "One prepared to take over from leading actor" , "Sub" , "In a state of unconsciousness" .)
