Which term describes the standard, non-proprietary name assigned to a drug's active ingredient?

The term that describes the standard, non-proprietary name assigned to a drug's active ingredient is known as the Generic Name. This name is established by conventions and guidelines set by organizations such as the World Health Organization (WHO) and the U.S. Adopted Names Council (USANC). Generic names are used internationally and are not tied to any particular manufacturer, allowing for universal recognition of the drug's active ingredient.

This standardization ensures that healthcare professionals and patients can communicate regarding medications without confusion caused by different trade or brand names that may be used in various markets. Unlike trade names or brand names, which can vary by manufacturer, the generic name remains consistent regardless of who produces the medication. This focus on the active ingredient allows for greater clarity and safety in pharmacology and prescribing practices.
