What is the unique number assigned to each medication approved by Health Canada for use?

The unique number assigned to each medication approved by Health Canada is the Drug Identification Number (DIN). This number serves as a specific identifier for each drug product, ensuring a standardized way to recognize and manage medication across various healthcare settings. The DIN is critical for tracking the medication for safety, efficacy, and regulatory processes.

In Canada, the use of a DIN helps healthcare professionals and pharmacists accurately identify medications, thereby reducing the risk of medication errors and ensuring patient safety. It's important in drug recalls and safety announcements, enabling swift communication across the healthcare system regarding specific medications.

The other choices represent different types of identification numbers or acronyms that are not associated with the approval of medications by Health Canada. For example, HCDN and MAN do not pertain to drug identification, while MIN could pertain to another form of medication identification but is not utilized in Canada for drug approval. Thus, the Drug Identification Number stands out as the correct answer, highlighting its essential role in the healthcare landscape in Canada.
