Generic versions of buprenorphine are available for several formulations. These include generic options for transdermal patches and sublingual tablets used to treat opioid dependence and pain [1].
When will generic buprenorphine enter the market?
The market entry for generic buprenorphine has already occurred for many of its forms. For instance, generic versions of the buprenorphine/naloxone sublingual film, often used for opioid use disorder, have been available for some time [2].

How do generic buprenorphine products differ from brand-name versions?
Generic buprenorphine products are bioequivalent to their brand-name counterparts, meaning they deliver the same amount of the active ingredient into the bloodstream.

The cost is also a significant difference, with generics generally being more affordable [2].
