Patients can purchase it domestically at a price of around 5,000 to 6,000 yuan. Please consult the local hospital pharmacy for specific prices. There are original lapatinib drugs and generic drugs abroad. The original drug is cheaper than the original drug in Türkiye, which costs more than 2,000 yuan. Generic drugs include Indian generic drugs and Bangladeshi generic drugs, and the price is around a few hundred yuan. The ingredients of domestic original drugs, foreign original drugs and generic drugs are basically the same.

拉帕替尼主要用于治疗HER2阳性的乳腺癌，包括转移性和局部晚期乳腺癌。它通常与其他药物或治疗方法一起使用，例如曲妥珠单抗（Trastuzumab）等。拉帕替尼通过干扰癌细胞内的信号传导途径，抑制异常的细胞增殖和生存。它通过阻止HER2和EGFR激酶的活性，减少了这些受体信号传导的能力。
