Larotrectinib has been launched in China and has not yet been included in medical insurance. Since it has not been launched in China for a long time, it may be difficult to purchase it in hospitals. For specific conditions, it is recommended to consult the local hospital pharmacy. In foreign markets, larotinib has two options: original drug and generic drug. Original drugs include the German version, the American version, the European version and the Hong Kong version, and the price is about 10,000 to 20,000 yuan. In comparison, generic drugs are much cheaper. There are Lao and Bangladeshi versions of generic drugs, and the price is around two to three thousand. It is worth noting that the ingredients of original drugs and generic drugs are basically the same.
