Migraine is often a chronic and disabling disorder. The objective of our study was to assess the efficacy and tolerability of levetiracetam (LEV) in adult migraine prophylaxis.
We conducted a prospective, randomized, placebo-controlled study. A total of 65 patients were randomized in a 1:1 ratio to receive LEV (n = 32) or placebo (n = 33). Twenty-five patients completed the study in the LEV group and 27 patients in the placebo group. Thirteen subjects discontinued early during the trial. After a 1-month run in period, LEV was started at a dose of 250 mg/d (or the matching placebo) and was increased by 250 mg/wk until the final dosage of 1000 mg/d was reached. The titration phase was followed by maintained phase of 3 months.
In LEV group, we found a significant reduction in the frequency (attacks per month) of migraine (from 5.17 [SD, 1.19] at baseline to 2.21 [1.47] in the last 4 weeks) and also in severity of migraine from (2.75 [0.44] to1.29 [0.75]) as compared to the placebo group. Patients treated with LEV also reported a statistically significant reduction in the quantity of symptomatic drugs needed for symptom control as compared to the placebo group (P < 0.0001). The percentage of patients on LEV who experienced greater than or equal to 50% reduction in headache frequency was 64% compared with 22% for placebo.
Compared with the placebo group, LEV offers improvement in headache frequency and severity as well as it lowers the requirement for other symptomatic drugs in adult migraine patients.
偏头痛通常是一种慢性致残性疾病。我们研究的目的是评估左乙拉西坦(LEV)在成人偏头痛预防中的疗效和耐受性。
我们进行了一项前瞻性、随机、安慰剂对照研究。总共65例患者按1:1比例随机分组,分别接受LEV(n = 32)或安慰剂(n = 33)治疗。LEV组有25例患者完成研究,安慰剂组有27例患者完成研究。13名受试者在试验期间提前退出。经过1个月的导入期后,开始给予LEV 250 mg/d(或匹配的安慰剂),每周增加250 mg,直至达到最终剂量1000 mg/d。滴定阶段之后是3个月的维持阶段。
与安慰剂组相比,LEV组偏头痛发作频率(每月发作次数)显著降低(从基线时的5.17[标准差,1.19]降至最后4周的2.21[1.47]),偏头痛严重程度也显著降低(从2.75[0.44]降至1.29[0.75])。与安慰剂组相比,接受LEV治疗的患者报告用于症状控制的对症药物数量在统计学上也显著减少(P < 0.0001)。头痛频率降低大于或等于50%的LEV治疗患者比例为64%,而安慰剂组为22%。
与安慰剂组相比,LEV可改善成人偏头痛患者的头痛频率和严重程度,并降低对其他对症药物的需求。
