Generic Drugs
What are Generic Drugs?
A generic drug is identical, or bioequivalent to a brand name drug in
dosage form, safety, strength, route of administration, quality,
performance characteristics and intended use. Although generic drugs are
chemically identical to their branded counterparts, they are typically
sold at substantial discounts from the branded price. According to the
Congressional Budget Office, generic drugs save consumers an estimated $8
to $10 billion a year at retail pharmacies. Even more billions are saved
when hospitals use generics.
Drug companies must submit an abbreviated new drug application (ANDA) for
approval to market a generic product. The Drug Price Competition and
Patent Term Restoration Act of 1984, more commonly known as the
Hatch-Waxman Act, made ANDAs possible by creating a compromise in the drug
industry. Generic drug companies gained greater access to the market for
prescription drugs, and innovator companies gained restoration of patent
life of their products lost during FDA's approval process.
New drugs, like other new products, are developed under patent protection.
The patent protects the investment in the drug's development by giving the
company the sole right to sell the drug while the patent is in effect.
When patents or other periods of exclusivity expire, manufacturers can
apply to the FDA to sell generic versions. The ANDA process does not
require the drug sponsor to repeat costly animal and clinical research on
ingredients or dosage forms already approved for safety and effectiveness.
This applies to drugs first marketed after 1962.
Health professionals and consumers can be assured that FDA approved
generic drugs have met the same rigid standards as the innovator drug. To
gain FDA approval, a generic drug must:
contain the same active ingredients as the innovator drug (inactive
ingredients may vary)
* be identical in strength, dosage form, and route of administration
* have the same use indications
* be bioequivalent
* meet the same batch requirements for identity, strength, purity, and
quality
* be manufactured under the same strict standards of FDA's good
manufacturing practice regulations required for innovator products
