These differences in formulation can affect factors like absorption rate, which in turn may influence efficacy and potential side effects. However, the FDA requires generic drugs to demonstrate bioequivalence to their brand-name counterparts, ensuring that they produce the same therapeutic effects.

Regulatory Processes and Safety

Before generic drugs can be approved for sale, they must undergo rigorous regulatory processes. These processes ensure that generic medications meet the same quality, safety, and effectiveness standards as their brand-name counterparts. Generic drug manufacturers are required to provide evidence that their product is equivalent to the brand-name drug in terms of dosage form, strength, route of administration, and more.
