Generic medications are drugs that have the same active ingredients as brand-name medications, but are typically sold under their chemical or generic name. They are manufactured and marketed by companies other than the original brand-name manufacturer, and are usually less expensive than their brand-name counterparts.

Generic medications are approved by regulatory authorities such as the MHRA in the United Kingdom, based on their safety, effectiveness, and quality. They must meet the same quality and safety standards as brand-name medications and are required to contain the same active ingredient, strength, dosage form, and route of administration.

Generic medications are often a more affordable option for patients, as they are typically priced significantly lower than brand-name medications. This can be particularly important for patients who rely on long-term medication therapies, as the cost savings can add up over time.
