Abstract: In maintenance patients methadone has been shown to produce considerable changes in opioid effects and withdrawal over the dosing interval. As a partial agonist buprenorphine may be expected to produce smaller changes, but the nature and magnitude of these changes have only been described for single doses. In the present study opioid effects and withdrawal were described in patients maintained on buprenorphine. Twenty four opioid dependent subjects were administered 16 mg buprenorphine tablets sublingually for 10 days. On day 10 plasma samples were collected and physiological, subjective and observer-rated measures collected pre-dose and at 14 time points during the dosing interval. No significant respiratory depression was observed. Consistent with the partial agonist properties of buprenorphine, other physiological and subjective changes were also of small magnitude. However, even at a once daily dose of 16 mg some patients experienced significant opioid withdrawal that was maximal at the end of the dosing interval. Buprenorphine maintenance should be associated with a high level of safety and a low level of disruption caused by changing opioid effects over the dosing interval, but some patients may require high doses or other strategies to completely suppress withdrawal.
