What are the different types of buprenorphine? Though predominantly used as a sublingual film, buprenorphine can also be delivered via transbuccal, transdermal, subdermal (implant), subcutaneous, and parenteral routes (see table). Several include combination naloxone formulations (eg, suboxone) that prevent an opioid high associated with direct injection. #Pharmacology #Buprenorphine #Formulations #Types #Comparison #Table #Suboxone #Subutex #Addiction
