Which name refers to the official name of a drug that is not trademarked?

The official name of a drug that is not trademarked is known as the generic name. This name is assigned by the relevant regulatory authority and is universally accepted, allowing for consistent identification and use of the medication across different manufacturers and locations. The generic name of a drug typically reflects its chemical structure or pharmacological class, making it easier for healthcare professionals and patients to understand its properties and uses.

Unlike brand or trade names, which are specific to the manufacturer and often trademarked, the generic name allows for multiple companies to produce and market the same medication once the original patent expires. This encourages competition and can lead to lower prices for consumers while maintaining the same active ingredients and therapeutic effects. Understanding the distinction between the generic name and other names is crucial for effective medication administration and patient education.
