A peer isn't producing laxatives (9)

I believe the answer is:

aperients

'laxatives' is the definition.
('aperient' can be a synonym of 'laxative')

'a peer isn't producing' is the wordplay.
'producing' indicates anagramming the letters.
'peer'+'isnt'='peerisnt'
'peerisnt' anagrammed gives 'perients'.
'a'+'perients'='APERIENTS'

I've seen this clue in the Sydney Morning Herald.
