Drug aiming to eliminate the onset of gout (7)
I believe the answer is:
'drug' is the definition.
(aspirin is a kind of drug)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for aspirin that I've seen before include "Commonly used pain-killer", "headache cure", "Anti-inflammatory tablet", "Headache killer?", "Analgesic compound".)
