Generic drugs (generics) are vital to the sustainability of health care systems, especially in developing areas with low resources. Ensuring benefit to patients through the approval and delivery of generics that meet quality standards remains essential. Generics are expected to be bioequivalent and interchangeable with the innovator's drug product's reference formulation. Aside from certain instances were such generics are found to be spurious, falsely-labelled, falsified, or counterfeit; all would have passed local regulatory approvals in manufacturing and importing countries before becoming available for patient prescription.
