Treatment outcome for flexible dosing buprenorphine maintenance treatment.

BACKGROUND AND OBJECTIVES

Achieving the best treatment outcome with the least cost should be the goal for buprenorphine office-based treatment.

METHODS

We conducted an observational retrospective chart review to compare the treatment outcome for patients (n = 56) receiving high dose of buprenorphine (above 16 mg daily) and patients (n = 21) receiving moderate doses (8-16 mg daily).

RESULTS

The percentages of the first four urine drug screens (UDS) positive for opiates were significantly higher for the high-dose group than for the moderate-dose group (F = 7.93, df = 7, p < .0001). However, the percentages of the most recent four UDS positive for opiates were not statistically significant (F = .62, df = 7, p = .74). The difference in the percentages of the first and last UDS for the high-dose group showed significant reduction from admission to most recently but there was no significant difference for the moderate-dose group (t = 3.1, df = 105, p = .002 for the high-dose group and t = 1.1, df = 40, p = .27 for the moderate-dose group).

CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE

Using flexible buprenorphine dosing schedule with the option of titrating the dose up to 32 mg daily may offer better treatment outcome for patients who would not respond to the lower dose range.
