为此,来自美国学者Jacqueline French教授等人进行了一项对照研究,评估普瑞巴林单药治疗部分性癫痫发作的疗效和安全性。研究证实普瑞巴林在20周的治疗期内治疗部分性癫痫发作患者安全有效,研究发表于2014年2月份的《神经病学》杂志中。

研究入选在8周时间内采用1-2种抗癫痫药物治疗,但不能完全控制的部分性癫痫发作患者,在基线随机分配接受普瑞巴林600或150mg/d(4:1)双盲单药治疗20周(8周转换期,12周单药治疗期)。主要终点为普瑞巴林治疗癫痫的退出率,如果退出率的95%可信区间(CI)的上限低于历史对照阈值的74%,认为治疗有效(在转换期采用68%的阈值)。

该研究在125例患者中期分析取得积极的疗效之后就提前终止。整个研究入选了161例患者,对148例患者评估了疗效。诊断为癫痫的平均年限为14年。总体来说,54.3% (600 mg/d) 以及46.9% (150 mg/d)的患者完成了20周双盲治疗。600mg/d治疗组患者癫痫相关退出率远远低于74%以及68%的阈值。600mg/d治疗组中8例患者和150 mg/d治疗组2例患者通过普瑞巴林单药治疗达到无癫痫发作。普瑞巴林的总体安全性与之前的研究一致。

研究者总结道,该研究提供了III类证据,证实部分性癫痫发作控制不佳的患者转换为普瑞巴林单药治疗,与转换为安慰剂单药治疗的历史对照者相比,癫痫相关的退出事件更少。该研究对于那些打算将患者已有的治疗方案转换为普瑞巴林单药治疗的临床医师来说十分重要。
