Embase is a biomedical and pharmacological database with over 30 million citations. Don’t forget to use Embase, and not solely PubMed, when doing literature reviews on health topics.
Besides strong coverage in pharmacology and toxicology (including economic evaluations), Embase covers biochemistry, biomedical engineering & medical devices, clinical medicine, genetics, healthcare policy & management, infectious diseases, microbiology, molecular biology, and occupational and environmental health. Over 8,500 journals from over 90 countries are indexed, as well as conference abstracts from over 6,000 conferences.
Use Embase’s indexing system, Emtree (pdf), to build strong and precise searches, particularly on disease and drug/substance topics. In addition, Chemical Abstracts Service (CAS) Registry Numbers are generated for all drug/substance terms in each citation.
Use Embase off-campus via proxy server or VPN. Use UC-eLinks to get full text of articles.
