At this time, generic Sonata is available in two strengths. The FDA has determined that the generic versions of the drug are equivalent to the brand-name Sonata, although they are allowed to use different inactive ingredients. Sandoz, Roxane Laboratories, and Teva Pharmaceuticals are a few of the companies that manufacture generic Sonata.
Sonata is manufactured by King Pharmaceuticals, Inc. However, the patent for Sonata has expired, and the medication is now available in generic form.
Generic Sonata capsules are available in the following strengths:
- Zaleplon 5 mg
- Zaleplon 10 mg.
The generic version of Sonata is currently made by the following manufacturers:
- Roxane Laboratories, Inc.
- Genpharm, L.P.
- Teva Pharmaceuticals
- Upsher-Smith Laboratories, Inc.
- Aurobindo Pharma USA, Inc.
- Unichem, Inc.
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 each generic a rating. An "AB" rating means that the FDA has determined that a generic medication is equivalent to a brand-name medication. All of the generic zaleplon versions currently available have an "AB" rating, meaning they should be equivalent to Sonata.
However, generic medications are allowed to have different inactive ingredients than the brand-name medication. This might include fillers or dyes or other ingredients that may cause problems for people with allergies or sensitivities.
