Osimertinib/The original drug of Osimertinib has now been launched in the domestic market and has also been included in the national medical insurance system, so domestic patients can easily purchase it. Its selling price is roughly in the range of three to four thousand yuan, but for specific price information and details of medical insurance reimbursement, it is recommended that patients directly consult their local hospital or pharmacy to obtain the most accurate data. On the other hand, the price of foreign generic drugs is relatively low, especially the generic drugs listed in Laos and Bangladesh. Most of them only cost a few hundred yuan, which is far lower than the price of domestic original drugs. It is worth mentioning that these generic drugs are highly similar in ingredients to the original drugs, providing patients with another cost-effective treatment option.
