title: Buprenorphine: new treatment of opioid addiction in primary care.
abstract: OBJECTIVE
  To review the use of buprenorphine for opioid-addicted patients in primary care.
  
  
  METHODS
  The MEDLINE database was searched for literature on buprenorphine from 1980 to 2009. Controlled trials, meta-analyses, and large observational studies were reviewed.
  
  
  RESULTS
  Buprenorphine is a partial opioid agonist that relieves opioid withdrawal symptoms and cravings for 24 hours or longer. Buprenorphine has a much lower risk of overdose than methadone and is preferred for patients at high risk of methadone toxicity, those who might need shorter-term maintenance therapy, and those with limited access to methadone treatment. The initial dose should be given only after the patient is in withdrawal. The therapeutic dose range for most patients is 8 to 16 mg daily. It should be dispensed daily by the pharmacist with gradual introduction of take-home doses. Take-home doses should be introduced more slowly for patients at higher risk of abuse and diversion (eg, injection drug users). Patients who fail buprenorphine treatment should be referred for methadone- or abstinence-based treatment.
  
  
  CONCLUSIONS
  Buprenorphine is an effective treatment of opioid addiction and can be safely prescribed by primary care physicians.
