Clint sent us some medication (7)
I believe the answer is:
linctus
'some medication' is the definition.
(thesaurus)
'clint sent us' is the wordplay.
'sent' indicates anagramming the letters (send can mean to excite or stimulate).
'clint' anagrammed gives 'linct'.
'linct'+'us'='LINCTUS'
(Other definitions for linctus that I've seen before include "Cough medicine" , "The prescription" , "Special formulation" , "Soothing drink" , "Thick liquid medicine" .)
