What is the difference between a generic and a brand-name drug?

The distinction between a generic drug and a brand-name drug lies primarily in the marketing and identification aspect. A brand-name drug is developed and marketed under a specific trademarked name given by the pharmaceutical company that originated it. This name represents the company's brand identity and is typically associated with extensive research, marketing, and development efforts.

On the other hand, a generic drug contains the same active ingredients as the brand-name counterpart and is considered to be bioequivalent. However, it is marketed under its chemical name or a non-proprietary name, without the brand's trademark. The formulation, strength, dosage, and administration route are often identical to that of the brand-name drug, ensuring similar therapeutic effects.

Due to the lack of a trademark, generic drugs are usually offered at a lower price point, enhancing access to medications for patients. Therefore, option B accurately captures the fundamental difference between these two types of drugs. Other options do not effectively address the core distinction and may also contain inaccuracies related to efficacy, pricing, or side effects.
