Find synonyms of an active substance — ctrFindActiveSubstanceSynonyms • ctrdata

An active substance can be identified by a recommended international nonproprietary name (INN), a trade or product name, or a company code(s). To find likely synonyms, the function retrieves from CTGOV2 the field protocolSection.armsInterventionsModule.interventions.otherNames. Note this does not seem to be based on choices from a dictionary but may be manually filled, thus is not free of error and needs to be checked.

Usage

Arguments

activesubstance: An active substance, in an atomic character vector
verbose: Print number of studies found in CTGOV2 for `activesubstance`

Value

A character vector of the active substance (input parameter) and synonyms, or NULL if active substance was not found and may be invalid
