Buprenorphine is a partial agonist at the mu-opioid receptor and an antagonist at the kappa opioid receptor.

The resulting product is a solid matrix that releases buprenorphine slowly, through the process of diffusion. The product is placed subcutaneously, normally in the upper arm in a simple 15-minute office procedure, and is removed in a similar manner at the end of the treatment period.
