Generic Metadate ER
Generic Metadate ER is sold under the name Methylphenidate Extended-Release tablets. It is available in two different strengths, 10 mg and 20 mg, and is manufactured by several drug companies. The U.S. Food and Drug Administration has given generic Metadate ER an "AB" rating, which means that while it may contain different inactive ingredients, it is equivalent to the brand-name version.
Metadate ER® (methylphenidate extended-release) is a prescription medication that has been licensed to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy.
The drug was first manufactured by UCB, Inc. However, the patent has since expired, which means that generic Metadate ER is now available as well.
Generic Metadate ER is sold under the name Methylphenidate Extended-Release tablets, which come in the following strengths:
- Methylphenidate Extended-Release tablets 10 mg
- Methylphenidate Extended-Release tablets 20 mg.
Generic Metadate ER is made by several manufacturers, including:
- Mallinckrodt, Inc.
- Sandoz Pharmaceuticals
- Watson Laboratories.
All generic medications must have certain tests to compare them to brand-name medications. The U.S. Food and Drug Administration (FDA) then looks at these tests to decide if the generic versions are equivalent to the brand-name medications and assigns a rating to each one. An "AB" rating means that the FDA has determined that a generic medication is equivalent to a brand-name medication. All of the generic Metadate ER versions that are currently available have an "AB" rating, meaning they should be equivalent to brand-name Metadate ER.
However, generic medications are allowed to have different inactive ingredients than the brand-name medication. This might include fillers or dyes or other ingredients, which may cause problems for people with certain allergies or sensitivities.
