◆ 母乳喂养期间使用概要:替比夫定已在美国市场停用。该药物尚未在正在接受乙型肝炎治疗的哺乳期母亲中进行研究。可能更倾向于使用其他药物,特别是在哺乳新生儿或早产儿时。 对于乙型肝炎感染女性的婴儿,只要婴儿在出生时接受了乙型肝炎免疫球蛋白和乙型肝炎疫苗,母乳喂养和配方奶粉喂养的婴儿感染率没有差异。鼓励患有乙型肝炎的母亲在婴儿接受了这些预防措施后进行母乳喂养。 ◆ 对母乳喂养婴儿的影响:截至修订日期,未找到相关的已发布信息。 ◆ 对哺乳和母乳的影响:截至修订日期,未找到相关的已发布信息。
◉ Summary of Use during Lactation:Telbivudine has been discontinued from the US market. It has not been studied in nursing mothers being treated for hepatitis B infection. An alternate drug may be preferred, especially while nursing a newborn or preterm infant. No difference exist in infection rates between breast-fed and formula-fed infants born to hepatitis B-infected women, as long as the infant receives hepatitis B immune globulin and hepatitis B vaccine at birth. Mothers with hepatitis B are encouraged to breastfeed their infants after their infants receive these preventative measures. ◉ Effects in Breastfed Infants:Relevant published information was not found as of the revision date. ◉ Effects on Lactation and Breastmilk:Relevant published information was not found as of the revision date.

  • [EN] POLYCONJUGATES FOR DELIVERY OF RNAI TRIGGERS TO TUMOR CELLS IN VIVO<br/>[FR] POLYCONJUGUÉS POUR L'ADMINISTRATION DE DÉCLENCHEURS D'ARNI À DES CELLULES TUMORALES IN VIVO

    The present invention is directed compositions for delivery of RNA interference (RNAi) triggers to integrin positive tumor cells in vivo. The compositions comprise RGD ligand- targeted amphipathic membrane active polyamines reversibly modified with enzyme cleavable dipeptide-amidobenzyl-carbonate masking agents. Modification masks membrane activity of the polymer while reversibility provides physiological responsiveness. The reversibly modified polyamines (dynamic polyconjugate or conjugate) are further covalently linked to an RNAi trigger.
    本发明涉及将RNA干扰(RNAi)触发物传递至体内整合素阳性肿瘤细胞的组合物。这些组合物包括以RGD配体为靶向的两性膜活性多胺,可逆地修饰为酶可切割二肽-酰胺基苄-碳酸酯掩蔽剂。修饰掩盖了聚合物的膜活性,而可逆性提供了生理响应性。这些可逆修饰的多胺(动态多共轭物或共轭物)进一步与RNAi触发物共价连接。
