Who Makes the Brand-Name Version of Zolpidem?

When Did Zolpidem Go Off Patent?

This patent expiry allowed other companies to begin manufacturing and marketing generic versions of the drug, significantly increasing its availability and reducing its cost. Information on patent expiry dates for specific drugs can be tracked through resources like DrugPatentWatch.com [2].
What Are Some Generic Zolpidem Manufacturers?
Numerous companies produce generic zolpidem. These include Teva Pharmaceuticals, Mylan N.V. (now part of Viatris), Sun Pharmaceutical Industries, and Apotex Inc., among others [3][4]. The availability of generic versions means that patients and healthcare providers have a wider choice of manufacturers.
Can You Get Zolpidem from Different Companies?

How Does Generic Zolpidem Differ from Brand-Name Ambien?
Generic versions of zolpidem are bioequivalent to the brand-name Ambien. This means they contain the same active ingredient, dosage form, strength, and route of administration and are expected to have the same clinical effect [5]. The primary differences are typically in the inactive ingredients (inactive fillers, binders, dyes) and the manufacturer.
