Every marketed drug has three distinct names:
-
Chemical Name: This is the precise description of the drug's molecular structure and is usually quite complex. For example, the chemical name for MDMA is 3,4-methylenedioxy-methamphetamine. This name is assigned when a new chemical entity (NCE) is developed.
-
Generic Name (Nonproprietary Name): This is a simpler, shorter name that's assigned by regulatory bodies like the WHO. It's unique to each drug and isn't protected by trademark. For example, the generic name for ibuprofen is ibuprofen, regardless of the brand name. The generic name is crucial for simplifying communication and ensuring accurate identification.
-
Brand Name (Proprietary Name, Trade Name): This is the name under which the pharmaceutical company markets the drug. It's a trademark and is protected by intellectual property rights. This name is often catchy and memorable for marketing purposes. For example, Advil and Motrin are brand names for ibuprofen.
These three names—chemical, generic, and brand—are essential for clear identification, communication, and regulation within the pharmaceutical industry. Knowing the distinction between these names helps patients and healthcare professionals understand and correctly use medications.
