Resolve a free-text drug name to ingredient CUIs (IN/PIN)

Uses RxNav approximateTerm, then fetches properties for each candidate and filters to ingredient-type concepts (TTY IN and, optionally, PIN).

Usage

find_ingredients(
  term,
  max_entries = 10,
  include_pin = TRUE,
  show_progress = interactive()
)

Arguments

term

Character vector (free text).

max_entries

Integer. Max approximate-term candidates per input (default 10).

include_pin

Logical. Include precise-ingredient (PIN) CUIs (default TRUE).

show_progress

Logical. Show a progress bar in interactive sessions. Progress is shown only when at least 5 inputs are supplied.

Value

A tibble with columns: input, rxcui, name, tty, score.

Examples

if (identical(Sys.getenv("RXREF_ONLINE"), "1")) {
  find_ingredients("metformin")
}
