NLM Medical Subject Headings (MeSH) Guide for searching
If you are searching PubMed, build your search strategy using NLM Medical Subject Headings (MeSH) or use the MeSH Browser search to find appropriate headings, subheadings, publication types and entry terms. The topics of drugs and pharmacology are broad but also overlap a number of other subject areas such as: analgesia, prescribing patterns, the drug industry, vaccines, clinical trials, substance use disorders, side effects, toxicology, herbal medicine, vitamins, dietary supplements and other areas listed in the table of contents. Since many areas are covered in a hierarchy, broad MeSH terms are presented. Click on a MeSH Database record and scroll down the record to find additional higher and subordinate topics when available in a hierarchy, under All MeSH Categories.
