Many strengths of brand-name Kadian (morphine sulfate ER) are available in generic form as well. The FDA has assigned these generics an "AB" rating, meaning they are considered equivalent to the brand-name medication.
Kadian® (morphine sulfate ER) is a prescription pain medication. It contains tiny, extended-release pellets that release morphine slowly and evenly throughout the day. It can be taken once or twice a day.
Brand-name Kadian is made by Actavis Elizabeth LLC and is marketed and distributed by Alpharma Pharmaceuticals LLC. The patents for this medication have expired, however, and it is now available in generic form as well.
Generic Kadian capsules are available in the following strengths:
- Morphine sulfate ER 10 mg
- Morphine sulfate ER 20 mg
- Morphine sulfate ER 30 mg
- Morphine sulfate ER 50 mg
- Morphine sulfate ER 60 mg
- Morphine sulfate ER 80 mg
- Morphine sulfate ER 100 mg.
The 40-mg, 70-mg, 130-mg, 150-mg, and 200-mg strengths of Kadian are not yet available in generic form, for reasons that are unclear.
Generic Kadian is made by various manufacturers, such as Actavis and Watson Laboratories. Notice that Actavis also is the maker of brand-name Kadian. In fact, the Actavis version of generic Kadian is actually an "authorized generic," which means it is exactly the same as the brand-name product in every way (the capsules even look the same and are made by the same manufacturer), except it is marketed and labeled as a generic.
All generic medications must undergo 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 generics 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 Kadian versions currently available have an "AB" rating, meaning they should be equivalent to Kadian.
However, generic medications are allowed to have different inactive ingredients than the brand-name medication. This might include fillers, dyes, or other ingredients that may cause problems for people with allergies or sensitivities.
