Be sure to find out the generic name of the drug when you buy it. Trade name (brand name): In order to establish their own image and brand, many manufacturers or enterprises often register their products with trade names (brand names) to show their differences. Bamir, for example, is the trade name of aspirin, and the trade name (trade name) is mostly used in drug promotion. Consumers are familiar with the trade name (trade name). When buying drugs, we should pay attention to choosing brands with good quality and high reputation.
