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. Note this is mostly manually filled, thus may not be free of errors.

Usage

ctrFindActiveSubstanceSynonyms(activesubstance = "", verbose = FALSE)

Value

A named character vector of the active substance (input parameter), the MeSH term(s) and various names (other than the MeSH term) used in registered studies, or NULL if the active substance was not found and may be invalid. The active substances are ordered in decreasing number of occurrence.

Arguments

activesubstance

An active substance, in an atomic character vector

verbose

Print number of studies found in CTGOV2 for `activesubstance`

Examples

if (FALSE) {

ctrFindActiveSubstanceSynonyms(activesubstance = "imatinib")
