A generic drug is a drug defined as “a drug product that is comparable to a brand/reference listed drug product in dosage form, strength, quality and performance characteristics, and intended use”. There are Indian companies which manufacture and market these generic medicines after getting approval from Regulatory Authority of the country. These generic medicines contain the same active ingredients as the original formulation and are identical or within an acceptable bioequivalent range to the Innovator drug counterpart with respect to pharmacokinetic and pharmaco-dynamic properties. By extension, therefore, generics are considered identical in dose, strength, route of administration, safety, efficacy, and intended use. They are labeled with the name of the manufacturer and the adopted name (nonproprietary name) of the drug. When generic products become available, the market competition often leads to substantially lower prices and thereby make is affordable for large number of needy patients.
