对服用任何复方口服避孕药(含有雌激素与孕激素)的妇女来说,其血栓的总体风险仍然相对较低,每1万名服用药物的妇女中,每年额外增加6~14例病例。但近日,英国一项大型研究表明,服用新型口服避孕药的人群发生血栓的风险更高。静脉血栓栓塞(VTEs)在服用雌激素药物的妇女中更为常见,如果血栓移动并运行到心脏、大脑或肺部则有可能是致命的。新型复方避孕药包括孕激素屈螺酮、去氧孕烯、孕二烯酮或环丙孕酮,与包括左炔诺孕酮与炔诺酮在内的老款药物相比,新型 For women taking any combination of oral contraceptives, which contain estrogen and progestin, the overall risk of thrombosis is still relatively low, with an additional 6 to 14 additional cases per 10,000 women taking the drug. But recently, a large British study showed that people taking new oral contraceptives have a higher risk of thrombosis. Venous thromboembolism (VTEs) are more common in women taking estrogen drugs and may be lethal if they move to the heart, the brain, or the lungs. New compound contraceptives include progesterone drospirenone, desogestrel, gestodene or cyproterone, compared with older drugs, including levonorgestrel and norethindrone, the new
