In general cheap 162.5mg avalide otc blood pressure different in each arm, results from these analyses found significant improvements for gabapentin and pregabalin compared with placebo. One of the exceptions was that gabapentin was not superior to placebo in improving associated depressive symptoms. On HADS neither the depression nor anxiety scores were significantly different 105, 106 between pregabalin and placebo groups, with the exception of anxiety symptoms with 106 pregabalin 600 mg/d (difference from placebo -0. In the other pregabalin study by Mease, it was noted that other than sleep, secondary efficacy measures did not show any statistically significant difference between any of the treatment groups compared with placebo at 107 endpoint. Relapse 108 Crofford and colleagues reported the only long-term (6-month) trial that studied relapse of symptoms of fibromyalgia. The objective of the trial was to study the duration of efficacy of pregabalin in treating fibromyalgia. All patients underwent a 6-week open-label phase in which they received escalating doses of pregabalin to determine their optimal dosages. At the end of the open-label phase, responders (greater than 50% reduction in pain using a 100-mm visual analog scale and a self-rating of “much” or “very much” improved on PGIC) entered a double-blind Antiepileptic drugs Page 37 of 117 Final Report Update 2 Drug Effectiveness Review Project phase in which patients in one arm received placebo and patients in the other arm received their optimal pregabalin dosage. The primary outcome was the time to loss of therapeutic response, defined as <30% reduction in pain from open-label baseline or worsening of fibromyalgia, requiring alternate treatment. Of 1051 patients enrolled in the open-label period, 566 were responders (53. The discontinuation rate in this double-blind trial was very high, with 81% of the placebo group and 62% of the pregabalin group discontinuing the study prior to 6 months. Time to loss of therapeutic response was longer for pregabalin than placebo (P<0. Comparing the first quartile, the median time to loss of therapeutic response was 7 days for placebo and 34 days for pregabalin. At end of the 6-month double-blind phase, 61% of placebo patients met loss of therapeutic response criteria, compared with 32% of pregabalin patients. Because all patients who withdrew from the study were counted as not having loss of therapeutic response in the primary analysis, sensitivity analysis was done counting these patients as having had loss of therapeutic response. This sensitivity analysis resulted in similar results, with a P<0. Several other sensitivity analyses were conducted; all found pregabalin superior to placebo. Migraine prophylaxis Previous systematic review 2 A Cochrane review by Chronicle and colleagues of antiepileptic drugs for migraine prophylaxis assessed the efficacy of carbamazepine, valproate, lamotrigine, gabapentin, and topiramate compared with placebo. Patients with chronic migraine, transformed migraine, or chronic daily headache were excluded from the Chronicle review. Reasons for excluding chronic migraine included concerns with inconsistencies in classification of chronic migraine and concerns with variability of response to treatment due to severity. Further discussion of these issues can be found in the publication. Chronicle and colleagues conducted meta-analyses by drug for migraine frequency and for the proportion of patients achieving ≥50% reduction in migraine frequency. Table 7 summarizes the results from placebo-controlled trials: Only lamotrigine was not statistically significantly superior to placebo. Before putting significant weight on the pooled estimates from their review, the authors point out that much of the included literature had several methodologic limitations. These included selective outcome reporting, misrepresentation of intention-to-treat analyses, and inadequate measures to minimize carryover effect in crossover studies. Differences across these studies make qualitative indirect comparisons unwise. Despite these caveats, however, pooled effects for antiepileptic drugs were likely more robust in their estimates than effects estimated for agents with 1 trial. Therefore, more evidence supports use of valproate or topiramate for migraine prophylaxis than carbamazepine, lamotrigine, or gabapentin (Table 7). Furthermore, results from active-control trials that compared valproate and topiramate with propranolol or flunarizine (2 agents with evidence on efficacy) provided additional support for this conclusion.
