What is drug information?

Drug information (medication information, or drug informatics) refers to the discovery, use, and management of information regarding the use of medications. Drug information runs the gamut from identification, cost, and pharmacokinetics to dosage and adverse effects. Information about anatomy, health, or diseases might be needed to better utilize the drug information.

Classification of Information Sources

Drug information sources have been traditionally classified in three different categories: primary, secondary, and tertiary:

PRIMARY SOURCES

Primary literature consists of clinical research studies and reports, both published and unpublished. Not all literature published in a journal is classified as primary literature, for example, review articles or editorials are not primary literature.

SECONDARY SOURCES

Secondary literature refers to references that either index or abstract the primary literature, with the goal of directing the user to relevant primary literature.

TERTIARY SOURCES

Tertiary sources provide information that has been summarized and distilled by the author or editor to provide a quick easy summary of a topic. Some examples of tertiary resources include textbooks, compendia, review articles in journals, and other general information, such as may be found on the Internet.
