仿制药巨头梯瓦（Teva）3月7日宣布，在美国推出Xeloda（希罗达，capecitabine，卡培他滨，150mg和500mg片剂）等效仿制药。Xeloda品牌药由罗氏旗下基因泰克（Genentech）销售。梯瓦Xeloda仿制药简化新药申请（ANDA）于2013年9月获FDA批准，是首个拿到批文的制药公司。

根据IMS数据，截止2013年12月，Xeloda品牌药（150mg和500mg片剂）在美国的销售额为7.54亿美元。

Xeloda是FDA批准的首个口服化疗药物，属于氟代嘧啶氨基甲酸酯类药物，是细胞周期特异性抗代谢类药物，药物进入人体经脱氧胞嘧啶酶激活后，由胞嘧啶核苷脱氨酶代谢为5-氟尿嘧啶（5-FU）。5-氟尿嘧啶作用于DNA合成期的肿瘤细胞，在一定条件下，可以阻止癌组织细胞分裂增生。

Xeloda于1998年获FDA批准，该药用于结直肠癌、胃癌、乳腺癌的治疗。Xeloda的美国专利于2013年12月14日到期。
