1. Tracking Drug Trade Names
in Biomedical Literature
2. Embase offers several options for monitoring
drug products in the biomedical literature.
Because each method entails varying ways searches are
executed, results for each may vary slightly.
Choose the option(s) that best suit your research needs.
3. Use Quick Search for fast and simple queries.
Extensive search matches (or “maps”) a drug trade
name to its equivalent Emtree preferred term
(usually its INN generic name).
It also “explodes” it to retrieve narrower terms (if
any), and also searches keywords from article titles,
abstracts and other database fields.
This option usually retrieves most literature available
in Embase; it may not be completely comprehensive.
4. Preliminary results appear above.
Note that the product name OxyContin has mapped to —
and is searched as -- the preferred index term
oxycodone. This means that Embase looks for papers
indexed with oxycodone regardless of whether the name
OxyContin appears or not.

5. Here, neither OxyContin nor
oxycodone appear in the
However, it does appear in the
Emtree drug index terms
field because the drug was
discussed in the body of the
original paper; therefore this
citation is still relevant.
6. Advanced Search provides many more search options, and
greater flexibility in query-building, than Quick Search.
As before, term mapping is automatically enabled (it can be
turned off, if desired).
Search also for synonyms… ensures that all possible variants
of a drug name are searched as well as the preferred drug term
currently used for indexing. Drug names occasionally change
over time, and old (replaced) names are retained in the Emtree
thesaurus as synonyms.
This option provides the most comprehensive retrieval.
7. Note the difference in retrieval when synonym
searching is included.
8. You can see the difference in the records retrieved by this
method by excluding them from the first search set using the
Boolean NOT operator, and then checking a few in detail.
9. Here, oxycodone does not appear as an index term, but it is
mentioned peripherally in the abstract.
10. Drug Search allows you
to take advantage of
special Embase drug
indexing — drug
subheadings and routes
of administration — for
more focused searching.
This option affords very
high search precision.

Here, the set from Drug Search only finds articles with
the term oxycodone in the records’ index term fields;
synonyms and keywords are not searched.
12. The first several options work well when comprehensive
retrieval of a drug topic is needed.
To find articles on a specific drug product name, use Field Search
to search within the Drug Trade Name field.
Along with indexing generic names, Embase records also include drug
trade names (plus manufacturer names) whenever they are mentioned
within the text of the original article.
This allows you to track individual products in published research literature:
• For pharmaceutical safety and efficacy reporting requirements
• For maintaining internal product databases
• For corporate intelligence (tracking competitor products)
• And much more

16. Note the preferred generic term oxycodone in
the index fields.
Drug trade names (plus drug manufacturer
names and countries, when available) are
displayed separately in their own fields.
17. Within Emtree Tool, you can use a drug product name to identify
its preferred Emtree index term, to see other trade names
associated with it, and learn other information about it.
Type a trade name in the Find Term box. The correct index

Synonyms appear at the
bottom of the page.
19. Synonyms include alternate drug and disease names, non-INN generic
nomenclature, trade names from around the world, chemical compound names,
laboratory codes, enzyme codes, and MeSH subject headings from MEDLINE.
If your search includes any of these names, it will automatically map to the
matching Emtree term — thus ensuring accurate and complete retrieval.
