Title

MeSH chemical headings and pharmacologic action

Abstract

National Library of Medicine's Medical Subject Headings (MeSH) terms for chemical compounds are arranged in 2 trees: for chemical structures; and for pharmacological action. In 1996, indexing policy changes were implemented which affected chemical terminology in the pharmacological action tree. The change also led to the creation of a new field, Pharmacological Action (PA), in the MeSH Vocabulary File Database. Demonstrates practical searching of MEDLINE and related databases using the PA field
