Drug class
Analgesics, Opioid clinical trials
A class of medicines: the studies that test any of its 32 members, each study once. Members are as MeSH files each medicine’s actions, and as the NCI Thesaurus classes newer ones.
Keep track of what changes. Save the analgesics, opioid studies recruiting or about to start, and get an email each week — studies that open, close, add sites or post results.
