Drug Information Portal Information Has Moved to PubChem
"...current drug information for over 53,000 substances. The Portal links to sources from the NLM, the National Institutes of Health (NIH), and other government agencies such as the U.S. FDA.
Current information regarding consumer health, clinical trials, AIDS–related drug information, MeSH® pharmacological actions, PubMed® biomedical literature, and physical properties and structure is easily retrieved by searching a drug name. A varied selection of focused topics in medicine and drug–related information is also available from displayed subject headings.
The Drug Portal retrieves by the generic or trade name of a drug or its category of usage. Records provide a description of how the drug is used, its chemical structure and nomenclature, and include up to 20 Resource Locators which link to more information in other selected resources. Recent additions to these Locators include clinical experience with drugs in PubMed Health (https://www.ncbi.nlm.nih.gov/pubmedhealth), substances reviewed in NLM LiverTox (https://livertox.nih.gov/), information from the Dietary Supplement Label Database (https://dsld.nlm.nih.gov/dsld/), and drug images in the Pillbox beta (https://pillbox.nlm.nih.gov/) database.
Data in the Drug Information Portal is updated daily, and is also available on mobile devices."
