概括

诺瑞乙酸 (NETA) 有效地阻止了使用伊格斯特勒植入物的长期出血. 虽然短期使用是安全的,但并不能防止将来的出血复发.

科学领域:

生殖医学
药理学

背景情况:

长期出血是使用乙格斯特勒植入物的人的担忧.
有时使用额外的孕激素,但没有强有力的证据.

研究的目的:

评估10 mg/天口服诺列西酸盐 (NETA) 对使用乙格斯特勒植入物的长期出血的疗效和安全性.

主要方法:

一个随机,受控,盲目的多中心试验 (IMPLANET) 在巴西.
参与者每天接受10毫克口服NETA或安慰剂,直到出血停止或持续30天.
主要结局:最多7粒药后止血;次要结局包括复发和安全性.

主要成果:

与安慰剂相比,NETA显著增加了止血率 (86. 7% 与多达7片药物的48. 9% 相比).
NETA导致治疗失败率较低 (2. 2% 与 17. 8% 相比),治疗日数较少,无出血日数较多.
使用NETA与更短的出血复发时间和更长的试验参与有关.

结论:

短期10毫克/ 天的NETA是有效的和安全的停止长期出血在etonogestrel植入物使用者.
NETA 不能防止长期出血的复发.
