Ambien vs generic: are they the same?
Ambien is the originator brand for the active ingredient Zolpidem. Once the original patent expired, authorised generic versions of the same active ingredient became available. For most users at 5mg, 10mg, 6.25mg CR, 12.5mg CR, the practical question is: is the generic just as good, and what really differs?
What is the same
Authorised generics of Zolpidem contain the same active substance at the same 5mg, 10mg, 6.25mg CR, 12.5mg CR strength as Ambien, with regulator-required bioequivalence to the originator. Clinical effect is, on average, the same. According to the prescribing information, generics meet the same regulatory standard and can substitute for the brand in most patients.
What can differ
Differences include manufacturer, country of production, excipients, tablet appearance, packaging and price. A small minority of patients react to a specific excipient that varies between manufacturers. Price is usually significantly lower for generics — often the most decisive practical difference for chronic use.
