aperitive

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

'a laxative' is the definition.
Both the answer and definition are singular nouns.
Perhaps you can see a link between them that I don't see?

'after a tripe spread i have' is the wordplay.
'after' means one lot of letters go next to another.
'spread' is an anagram indicator.
'i have' becomes 'I've' (contraction of 'I have').
'tripe' with letters rearranged gives 'perit'.
'a' put next to 'perit' is 'aperit'.
'aperit'+'ive'='APERITIVE'

(Another definition for aperitive that I've seen is " Drink to stimulate appetite".)
