“…8,15 In a trial of similar design evaluating pregabalin ER (330-495 mg) in adults with fibromyalgia, the primary efficacy end point (ie, time to loss of therapeutic response) was met, but the trial did not demonstrate efficacy in a key secondary end point (ie, mean change from baseline). 8,16,30 Similarly, a double-blind, randomized, placebo-controlled trial of pregabalin ER (165-330 mg) in adults with partial onset seizures did not demonstrate that pregabalin is effective in reducing seizure frequency below that of placebo. 8,17 In all 3 trials, the safety profile of pregabalin ER was comparable to that reported previously for the IR formulation.…”
