sedated

I'm a little stuck... Click here to teach me more about this clue!

'given' is the definition.
Both the definition and answer are adjectives. Maybe they are linked in a way I don't understand?

I can't explain the remainder of the clue.

Can you help me to learn more?

(Other definitions for sedated that I've seen before include "Drugged" , "Given calming drugs" , "Under the influence of drugs" , "Dead set (anag) - tranquillised" , "Calmed with drugs" .)

I've seen this clue in the Evening Standard.
