ctrFindActiveSubstanceSynonyms: Find synonyms of an active substance

Description

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

ctrFindActiveSubstanceSynonyms(activesubstance = "", verbose = FALSE)

Value

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

Arguments

activesubstance

An active substance, in an atomic character vector

verbose

Print number of studies found in CTGOV2 for `activesubstance`

if (FALSE) {

ctrFindActiveSubstanceSynonyms(activesubstance = "imatinib")
