The only generic Exelon product available is the capsules. These come in four different strengths and are manufactured by Sun Pharmaceutical Industries, Watson Laboratories, and Dr. Reddy's Pharmaceutical Company. It is unclear when a generic version of Exelon patches or solution will become available.
Exelon® (rivastigmine) is a prescription medication. It is part of a group of medications known as acetylcholinesterase inhibitors. Exelon is approved to treat dementia due to Alzheimer's disease or Parkinson's disease. It is available in capsules, oral solution (liquid), or patches.
Exelon is made by Novartis Pharmaceuticals Corporation. Generic versions of some forms of Exelon (but not all) are currently available.
Generic Exelon capsules are available in the following strengths:
- Rivastigmine 1.5 mg
- Rivastigmine 3 mg
- Rivastigmine 4.5 mg
- Rivastigmine 6 mg.
Generic Exelon oral solution and patches are currently not available.
At this time, generic Exelon is made by a few different companies, including:
- Dr. Reddy's Pharmaceutical Company
- Sun Pharmaceutical Industries
- Watson Laboratories.
The first patent for Exelon patches expired in August 2012. However, generic versions are not yet available. This strongly suggests that other patents or exclusivity rights are still providing significant protection against generic competition. The next patent set to expire will do so in February 2014. This is the earliest predictable date that a generic version of the drug could become available.
However, other circumstances could come up to extend or shorten the exclusivity period. This could include such things as other patents for specific Exelon uses or lawsuits.
It is difficult to predict exactly when generic Exelon solution will become available. Since it is covered by the same patents as Exelon capsules, which are already available in generic form, it appears that there is nothing stopping generic manufacturers from making generic Exelon solution.
