Which route of administration is NOT typically associated with buprenorphine treatment?

Buprenorphine is often used for the treatment of opioid dependence and pain management, and it is available in several formulations that allow for different routes of administration. The oral tablet formulation, while available, is not commonly used due to its variable bioavailability and the fact that buprenorphine is primarily delivered through more effective routes such as sublingual, transdermal, or injectable forms. The routes that are typically associated with buprenorphine treatment include the sublingual route, which ensures better absorption, the transdermal patch that provides a continuous release, and intravenous injection, which allows for immediate effects.

Conversely, the oral tablet is not the preferred or most effective method for administration in therapeutic settings, as it does not consistently provide the desired therapeutic levels of buprenorphine due to its poor absorption when taken orally. Therefore, while buprenorphine may be available in an oral tablet form, it is not a common route of administration in practice, making this choice the one that is typically not associated with buprenorphine treatment.
