The Quality Standards for Generic Drugs

Are Discount Drugs of Inferior Quality?

"Most people believe that if something costs more, it has to be better quality..."says Gary Buehler, Director of FDA's Office of Generic Drugs. "In the case of generics (discount drugs), this is not true. The standards for quality are the same for brand name and generic products." (1)

When a brand name product has a generic competitor, this simply means that the brand name product has been around long enough for its patent to expire, which then allows generics (copy discount drugs) to be made. Most often generics will be the discount drugs found in these markets, and almost always they will be less expensive prescription drugs when compared to their brand name counterparts.

Despite their lower price, manufacturers of generic prescription drugs are required to meet rigorous quality standards before they can sell their generic 'discount drugs'. Pharmacies who source high quality generic products only from pharmaceutical manufacturers that comply with these strict international regulatory standards are providing quality alternatives to the branded equivalent. The quality standards of the lower cost generic products available are as high as they are for the most expensive original brand name drugs .

While the active ingredients in generic prescription drugs are the same as the active ingredients in their brand name counterparts, there may be differences in their appearance. (For example, the shape or the colour of a tablet.)

Sometimes different non-active ingredients may used to produce the final product. (For example, the non-active base in creams or diluents in nasal sprays.) However, the active ingredients, which give a drug its intended effect, are the same in generic prescription drugs and their brand name counterparts. None of these differences should alter the clinical effect of any approved generic discount drug.

The Current Use of Generic Prescription Drugs

The U.S. drug regulatory authority, the FDA, has approved more than 7000 generic discount drugs for use in the U.S. The approval process that all of these generic prescriptions drugs have completed is extremely intensive and multi-faceted. It covers quality, performance and labelling. Also, while these generics will inevitably become the country's discount drugs, the manufacturing facilities where they are to be made, are required by the FDA to be as good as those used to manufacture brand name drugs. This standard applies no matter where in the world the manufacturing facility is located.

Almost half of the prescriptions filled in 2002 in the U.S. were for generic drugs (1), these being the discount drugs of the country. This strong and growing demand for generic prescription drugs is testimony to their widespread acceptance by the health authorities, health professionals, and patients.

Pharmacies source high quality generic products only from pharmaceutical manufacturers that comply with strict international manufacturing standards. This means that any generic product supplied to a customer has complied with robust internationally accepted quality standards.


Some of the generic products sourced from internationally approved pharmaceutical manufacturers from India. The key companies that supply Indian generic pharmaceuticals are:

Some Technical Facts About The Generic Drug Approval Process

In the U.S and most developed countries generic drugs must show that they:

  • Contain the same active ingredients as the brand name drug (inactive ingredients may vary)

  • Are identical in strength, dosage, form, and route of administration

  • Are used for the same condition(s)

  • Are bio-equivalent (that is, they are available to the same extent in the body when taken or administered)

  • Meet the same batch requirements for identity, strength, purity, and quality

  • Are manufactured under the same strict standards of the FDA's good manufacturing practice as required for brand name products. (1)
