Drugs and Chemicals

• MeSH contains thousands of chemical terms, so it is likely that specific chemicals will be found by searching the MeSH Browser

• In many cases the work being cataloged is describing the functional aspect of a chemical: as therapeutic or diagnostic agents; environmental pollutants; endogenous substances, etc.

• In these cases, coordinate the chemical term with an appropriate Pharmacologic Action (PA) found in the MeSH record

• For example, the peptide Viomycin, has three Pharmacologic Actions in the MeSH browser:
  • Anti-Bacterial Agents
  • Antibiotics, Antitubercular
  • Protein Synthesis Inhibitors

• If your work is about the use of viomycin in the treatment of tuberculosis, coordinate Viomycin with Antibiotics, Antitubercular (as well as the disease term Tuberculosis or its specific types)

• If your work is on use of viomycin in some context that is not represented by the existing Pharmacologic Actions, search the MeSH D27 tree and select the most appropriate term
