Generic Cardene SR

Despite the fact that the patent for brand-name Cardene SR has expired, there are currently no approved generic Cardene SR products available on the market. It is unclear why this is so, and it is unknown when a generic version can be expected. It's important to keep in mind that nicardipine is the active ingredient in Cardene SR -- not a generic version.

An Overview of Generic Cardene SR

Cardene SR® (nicardipine SR) is a prescription medicine used for the treatment of high blood pressure (hypertension). It is part of a group of medications called calcium channel blockers. It is a long-acting version of Cardene; it is usually taken twice daily, compared to three times daily with short-acting Cardene.
Cardene SR is manufactured by Hoffmann-La Roche, Inc. There are no generic versions available at this time.

When Will Generic Cardene SR Be Available?

The patent for Cardene SR was set to expire in March 2010. However, March 2010 has come and gone, and there is still no generic Cardene SR, for reasons that are unclear. Perhaps no generic manufacturers have chosen to make a generic Cardene SR for financial reasons. Because it is unclear why a generic Cardene SR is unavailable, it is difficult to predict when exactly a generic version may become available.

Is Nicardipine a Generic Cardene SR?

The answer is no. Nicardipine is the active ingredient in Cardene SR, but it is not a generic version of Cardene SR. What can be confusing is that, oftentimes, the active ingredient of a drug is referred to as the "generic name." The generic name is different than a generic version of a medicine. In order for there to be a generic version of a medicine, the original medicine must have gone off patent and another company (besides the original manufacturer) would make the product.
