Pharmacologic Action Terms
Every drug and chemical MeSH heading has been assigned one or more headings that describe known pharmacological actions (PA).
- Since 1996, NLM indexers add the appropriate pharmacological action MeSH heading as well as the specific chemical MeSH heading to a citation when the action of the chemical is discussed in the article.
The pharmacological actions established for the MeSH Heading, Aspirin:
- Anti-Inflammatory Agents, Non-Steroidal
- Fibrinolytic Agents
- Platelet Aggregation Inhibitors
- Cyclooxygenase Inhibitors
A citation to an article that discusses aspirin used as an anti-inflammatory agent will be assigned:
Anti-Inflammatory Agents, Non-Steroidal
A citation to an article that discusses aspirin used to inhibit blood clotting will be assigned:
Platelet Aggregation Inhibitors
In a later section of this tutorial, you will learn how to use PubMed's MeSH Database to find MeSH terms for searching.
