Epilepsy Home > Generic Stavzor

There are currently no generic Stavzor (delayed release valproic acid) products available. All the patents for the medication have expired, so other drug companies can manufacture a generic version of the drug. Since the capsules are made using patent-pending technology, however, it is unlikely that other companies will produce a generic Stavzor at this time.

Generic Stavzor: An Overview

Stavzor™ (delayed release valproic acid) is a prescription medication approved to treat bipolar disorder and certain types of seizures. It is also approved for migraine prevention. Stavzor comes in specially designed, delayed-release soft gels.
Stavzor is made by Banner PharmaCaps, Inc. and is marketed and distributed by Noven Therapeutics, LLC.

When Will Generic Stavzor Be Available?

There do not appear to be any unexpired patents for Stavzor, which means that another manufacturer could make a generic version of Stavzor. However, the capsules are specially designed (as EnteriCare™ soft gels), using patent-pending technology. This means that it is unlikely that another company could make a generic version that was exactly like Stavzor.

Is Valproic Acid, Valproate, or Divalproex a Generic Version of Stavzor?

The answer is no. Both valproic acid and divalproex sodium (Depakote®, Depakote ER) are transformed into valproate in the digestive tract; valproate is a medical term that can be used to describe any of these medications (it is not a specific drug). Valproic acid is the active ingredient in Stavzor (as well as in the non-delayed release version, Depakene®). Stavzor is not equivalent to Depakote, Depakote ER, Depakene, or generic versions of these medications.
