The same drug produced by the same pharmaceutical factory has the same name, but the number of tablets is different, because the specifications and brands of drugs produced by the pharmaceutical factory are different, which is a bit strange. Now some factories may have multiple trademarks, but there are not many different trademarks for the same drug, and you may also buy fake drugs. You can go to official website and China Food and Drug Administration to check the drug standard number of the product, and the information of the drug you bought will be clear.
