Generic medicines (or: generics) are fully equivalent to the originator product in strength, route of administration, quality and performance characteristics, and intended use.
A generic drug must contain the same active ingredients as the original drug to be therapeutically equivalent and thus substitutable for the reference product. Generic medicines present the same quality and safety as the originator product. They are submitted to the same standards, which are enforced by the relevant regulatory authorities.
Production facilities are regularly inspected by the same authorities to ensure that they are compliant with the requirements for current Good Manufacturing Practice (cGMP).
