Mapping multi-ingredient generic drug terms

Hello! I am new to OMOP and we are doing our first mapping excercise. I just have some questions re mapping the drug list we have which is not based on a drug vocabulary.

We have the drug list in generic form without the form. Using the generic drug term “2,4 Dichlorobenzyl alcohol, Amylmetacresol, Ascorbic Acid”. I know that this is the generic for Strepsils.

Should I map this to the individual ingredient (first 3 below) or just pick the term with “oral lozenges” (4th line) even it is not stated in the original term.

Thank you very much in advance. If in case this has been discussed here or in any tutorial, I would really appreciate if you could refer me to any of the materials.



Welcome to the family.

Yes, the 4th line. You always have to go as detailed as your data give you information for.

Thank you so much @Christian_Reich! Apprecite the help!
