毒理性

• 在妊娠和哺乳期间的影响

母乳喂养期间使用总结：尽管没有进行测量，吸入型皮质类固醇被母体吸收进入血液和排入母乳中的量可能太小，不足以影响哺乳的婴儿。专家意见认为，吸入和口服皮质类固醇在哺乳期间使用是可以接受的。 ◉ 对哺乳婴儿的影响：目前没有报告任何皮质类固醇对哺乳婴儿有影响。有三名婴儿在母亲通过吸入器使用倍氯米松双丙酸酯治疗期间，被哺乳了6个月。 ◉ 对泌乳和母乳的影响：截至修订日期，没有找到相关的已发布信息。

◉ Summary of Use during Lactation:Although not measured, the amounts of inhaled corticosteroids absorbed into the maternal bloodstream and excreted into breastmilk are probably too small to affect a breastfed infant. Expert opinion considers inhaled and oral corticosteroids acceptable to use during breastfeeding. ◉ Effects in Breastfed Infants:None reported with any corticosteroid. Three infants were breastfed for 6 months during maternal treatment with beclomethasone dipropionate by inhaler. ◉ Effects on Lactation and Breastmilk:Relevant published information was not found as of the revision date.

  The invention features corticosteroids conjugated to either a charged group or a bulky group in a manner that resists in vivo cleavage, the resulting conjugate is a peripherally acting steroid with reduced activity in the central nervous system. The invention provides a method for treating a patient having an inflammatory disease by administering to the patient a corticosteroid conjugate.
