In areas of low malaria transmission, it is currently recommended that a single dose of primaquine (0.75 mg base/kg; 45 mg adult dose) be added to artemisinin combination treatment (ACT) in acute falciparum malaria to block malaria transmission. Review of studies of transmission-blocking activity based on the infectivity of patients or volunteers to anopheline mosquitoes, and of haemolytic toxicity in glucose 6-dehydrogenase (G6PD) deficient subjects, suggests that a lower primaquine dose (0.25 mg base/kg) would be safer and equally effective. This lower dose could be deployed together with ACTs without G6PD testing wherever use of a specific gametocytocide is indicated.
在疟疾传播水平较低的地区,目前建议在青蒿素类复方疗法(ACT)治疗急性间日疟时,增加一剂伯氨喹(0.75 毫克碱基/公斤;45 毫克成人剂量),以阻断疟疾传播。对基于患者或志愿者对按蚊感染性和葡萄糖-6-磷酸脱氢酶(G6PD)缺乏受试者溶血性毒性的研究进行综述后提示,较低剂量的伯氨喹(0.25 毫克碱基/公斤)更安全且同样有效。这种较低剂量可以与 ACT 一起使用,而无需在 G6PD 检测情况下在所有需要使用特定配子体杀灭剂的地方使用。
