Scale up in production for medicine (7)
I believe the answer is:
capsule
'medicine' is the definition.
(capsule is a kind of medicine)
'scale up in production' is the wordplay.
'in production' indicates anagramming the letters (I've seen this in other clues).
'scale'+'up'='scaleup'
'scaleup' with letters rearranged gives 'CAPSULE'.
'for' is the link.
(Other definitions for capsule that I've seen before include "Type of pill" , "Soluble case containing medicine" , "Small cylindrical case" , "Gelatine case for medicine" , "Gelatinous container with medicine inside" .)
