What differentiates generic drugs from brand-name drugs?

Generic drugs are distinguished from brand-name drugs primarily by their formulations, particularly in terms of inactive ingredients. While generic drugs contain the same active ingredients as their brand-name counterparts and are required to have the same strength, dosage form, and route of administration, they may include different inactive ingredients. These inactive ingredients can affect the formulation’s characteristics, such as absorption and stability, but they do not alter the therapeutic effectiveness of the drug.

For example, differences in fillers, preservatives, or colors can lead to variations in how the drug looks or feels, but they do not change how the drug works in the body. This allows generic drugs to be offered at lower prices while maintaining safety and efficacy. Understanding this aspect of generic drugs is essential for both healthcare providers and patients when considering medication options.
