There are no generic versions of Simcor (niacin extended-release/simvastatin) available at this time. The extended-release niacin component of the medication still has several unexpired patents -- the next group is set to expire in May 2017. This is the earliest predictable date that any generic Simcor products could become available.
Simcor® (niacin extended-release/simvastatin) is a prescription cholesterol medication. It contains two different active ingredients, simvastatin (Zocor®) and extended-release niacin (Niaspan®). It is approved for the treatment of unhealthy cholesterol levels (such as high "bad" cholesterol or low "good" cholesterol) and high triglycerides.
Simcor is manufactured by Abbott Laboratories. It is currently under the protection of a patent that prevents any generic Simcor from being manufactured in the United States.
The simvastatin component of Simcor is not protected by any patents (all the applicable patents have already expired, and simvastatin is available in generic form). However, the extended-release niacin component has several patents, the first several of which already expired in September 2013. The next group of patents for this drug is set to expire in May 2017. This is the next predictable date that a generic version of Simcor could become available.
However, there are other circumstances that could come up to extend or shorten the exclusivity period of Simcor. This could include such things as lawsuits or other patents for specific Simcor uses. Once Simcor goes off patent, there may be several companies that will begin manufacturing a generic Simcor drug.
