General Information
Subutex (Buprenorphine) is used to treat dependence or addiction to opioids (narcotics). This is also prescribed in lower dosages to treat pain and dependence on opioid painkillers like oxycodone (OxyContin).
How do Subutex (Buprenorphine) Tablets work?
Subutex (Buprenorphine) pain-relieving effect is due to partial agonist movement at mu-opioid receptors. This is also a kappa-opioid receptor antagonist. The partial agonist activity means that opioid receptor antagonists only partially reverse the effects of buprenorphine. The binding to the mu and kappa receptors results in reduced neuronal excitability and hyperpolarization. In addition, it slowly dissociates from its receptor. This reflection would account for the longer duration of action compared to morphine. And the unpredictability of its reversal by opioid antagonists and its low level of manifest physical dependence. Its receptor fixation half-life is 40 minutes which is significantly longer than morphine.
