Original drugs are mainly Turkish original drugs, and the price is relatively high, about3300About 100 yuan; generic drugs are mainly Indian generic drugs. The specifications of Indian generic drugs 100mg*120 are about a few hundred yuan, which is much cheaper than in China. The ingredients of foreign original drugs and generic drugs are basically the same as those of domestic imatinib.
