Next, a shorthand version of the chemical name or a code name such as RU is developed for easy reference among researchers. For example, phenytoin is the generic name and Dilantin is a brand name for the same drug, which is a commonly used antiseizure drug. The brand name is developed by the company requesting approval for the drug and identifies it as the exclusive property of that company. When a drug is under patent protection, the company markets it under its brand name. When the drug is off-patent no longer protected by patent , the company may market its product under either the generic name or brand name.
Other companies that file for approval to market the off-patent drug must use the same generic name but can create their own brand name. As a result, the same generic drug may be sold under either the generic name for example, ibuprofen or one of many brand names such as Advil or Motrin.
Generic and brand names must be unique to prevent one drug from being mistaken for another when drugs are prescribed and prescriptions are dispensed. To prevent this possible confusion, the FDA must agree to every proposed brand name. However, doctors often use the brand name on prescriptions, because it is easier to remember and doctors usually learn about new drugs by the brand name. Generic names are usually more complicated and harder to remember than brand names.
Brand names often suggest a characteristic of the drug. For example, Lopressor lowers blood pressure, Glucotrol controls high blood sugar glucose levels, and Skelaxin relaxes skeletal muscles. The term generic, when applied to such items as foods and household products, is used to describe a less expensive, sometimes less effective or lower-quality copycat version of a brand-name product. It is not enough for them In fact, generic drug makers manufacture many brand-name products for companies that control the brand names.
Sometimes, more than one generic version of a drug is available. For example, many manufacturers sell versions of acetaminophen , a nonprescription drug commonly used to relieve pain and fever.
In the United States, a company that develops a new drug can be granted a patent for the drug itself, for the way the drug is made, for the way the drug is to be used, and even for the method of delivering and releasing the drug into the bloodstream.
A few medicines, however, are always prescribed by the specific brand. This is because there are differences between the different brands in the amount you end up having in your body bioavailability. Examples of these type of medicines are:. In the UK there are strict quality controls before a product licence is granted for brand trade named or generic versions of medicines.
This means that a generic or brand name version of the same medicine will be of the same quality, and have the same action. I'm worried about falling asleep. Disclaimer: This article is for information only and should not be used for the diagnosis or treatment of medical conditions.

Combination products Generic prescribing What about quality of medicines? In the event of reports of negative patient side effects or other reactions, the FDA investigates and may require changes in how medicines both brand-names and generics are used or manufactured.
FDA will also communicate any information to the public as warranted. Generic drugs must meet the same high standards as brand-name drugs to receive FDA approval. FDA requires drug companies to demonstrate that the generic medicine can be effectively substituted and provide the same clinical benefit as the brand-name medicine. Generic drug applicants must show the generic medicine is the same as the brand-name in the following ways:.
