Claimed work with drugs (7)
I believe the answer is:
medical
'with drugs' is the definition.
(with medical drugs)
'claimed work' is the wordplay.
'work' is an anagram indicator.
'claimed' with letters rearranged gives 'MEDICAL'.
(Other definitions for medical that I've seen before include "Thorough health check" , "Of the science dealing with treatment of disease" , "Health check-up" , "Relating to treatment rather than surgery" , "Relating to doctors" .)
