Ingredient Name Search Implementation Guide

While the Medication Name Search and the Drug Name Search looks for the specific drug product information (such as brand names or dosage/strength/form), the Ingredient Name Search looks up drug ingredients only. This type of search is useful for looking up information for compounding drugs, drug products outside of our covered regions, or quickly finding the DrugBank ID and descriptions for a drug ingredient.

Ingredient Name Search is a valuable tool to assist in mapping between already existing systems and DrugBank. Since the active ingredient is the most basic level piece of information that all drugs have, mapping an existing system to DrugBank at this level will allow for the most available endpoint searches.

How does Ingredient Name Search work?

Step 1

To start an Ingredient Name Search, you would enter the following:
Step 2

Using the ingredient Bromhexine, the call to the API would look like this:

Note: In this response, the drug ingredient “Bromhexine” was queried, but it was misspelled as Bromhexien. Similar to the Drug Names Search, you can enable fuzzy=true to allow for misspelled drug ingredients to be searched within the database and return the most likely hits.

Tip: Ingredient Name Search also allows for autocomplete. The string that is in between the <em> and </em> is what is directly matched to the query, the remaining, outside of the <em> and </em>, is what is autocompleted. It's important to note that the fewer characters you input into your search and/or the more misspelled ingredient names you type, the more results you can anticipate, which creates an unnecessarily long list of medications to filter through.

Ingredient Name Search vs. Medication Name Search & Drug Name Search

Unlike the Medication Name Search and Drug Name Search, you do not need to set any region parameters for the Ingredient Name Search because you are not searching for a drug product related to any jurisdiction, just the ingredient.

Good to Know

The details returned from Ingredient Name Search are limited to the Drugbank ID and the CAS Number:

drugbank_idThe DrugBank ID of the drug being searched. Capturing this ID, you can connect to many other endpoints.
cas_numberUnique and unambiguous identifier that is assigned by the Chemeical Abstracts Service (CAS) for every chemical substance. A CAS No. for an active ingredient is universal, which you can use to search up a drug's information.

The drugbank_id can be used to access many other endpoints in Drugbank's Clinical API. Below are some of the endpoints that may be helpful.

Start with the basic call structure:

Then add the appropriate extension for the endpoint you are looking for in the table below.
