174A 9-week randomized double-blind, multi-center study of 172 patients, who after 1 week baseline evaluation are randomized to either fixed dose pregabalin starting at 75 mg BID for one week and increased to 150 mg BID for 7 weeks or flexibly dosed pregabalin given BID (75-300 mg/d) increased gradually over 4 weeks then maintained at that same dosing for 4 weeks.It is proposed that use of flexible dosing combined with nightly dosing would have similar pain relief to fixed dosing, would improve adherence, would have less side effects and would be more likely to improve sleep.
Fixed dosing of pregabalin: Week 1: 75 mg bid. Weeks 2 - 8: 150 mg bid. Week 9 (Days 57-60 and Days 61-63): 75 mg bid. Flexible dosing of pregabalin: Week 1: placebo in the AM and 75 mg nightly; Week 2: placebo in the AM and 150 mg nightly.; Week 3 placebo in the a.m., 225 mg nightly; Weeks 4 - 8 placebo in the a.m., 300 mg nightly. Week 9 (Days 57-60) placebo in the a.m,, 150 mg bid nightly and Days 61-63: placebo in the a.m., and 75 mg bid nightly.
