differential pricing policy meaning in English

差别计价政策

This price difference is largely due to the lack of generic competition in the second - line market : there are presently no generic versions of tfv and only one generic version of lpv r . there are generic versions of enterocoated ddi , but they are not available in south africa and many other countries . the manufacturer bristol - myers squibb has refused to include enterocoated ddi in its differential pricing policy , making the drug much more expensive
这个价格差异，是因为第二线药物?场缺乏仿制药的竞争：泰诺福韦目前尚未有仿制药，洛匹那韦利托那韦只有一种仿制药，地丹诺辛的肠溶剂型则在南非及许多国家找不到仿制药，加上原创药厂拒绝把地丹诺辛的肠溶剂型纳入其差别定价的政策之内，令该药价格更高。
