Aspirin is the most widely used antiplatelet drug, which plays an important role in the primary and secondary prevention of cardiovascular and cerebrovascular diseases.

Some can buy 100 tablets for two or three dollars, and some can only buy 30 tablets for more than ten dollars. How bad are they? How to choose long-term medication?

What's the difference in the price of aspirin? Dosage form and dosage difference Aspirin currently has three dosage forms: common dosage form, enteric-coated dosage form and effervescent dosage form.

In addition, the price varies with the dosage of aspirin. Generally, the dosage of enteric-coated tablets is small, which is 100mg/ tablet, and effervescent tablets are generally 500mg/ tablet. When aspirin is used to relieve fever and pain, it needs to be taken in large doses, 500mg each time, which is only suitable for short-term use and should be taken after meals. When aspirin is used for a long time to prevent thrombosis, a small dose of 75- 150mg should be taken every day, and 100mg is usually the best dose. The difference between APIs and generic drugs The original drug is patented, and generally other enterprises are not allowed to copy it within 20 years of patent protection. The original pharmaceutical manufacturers need to invest a lot of money and time in drug research and development. The production process is mature and advanced, with high purity, less impurities and good curative effect, so the price is generally more expensive. Even after the patent protection period, many generic drugs are fiercely competitive, and the reputation of the original drug is still a golden signboard, so the price will not drop sharply. Many patients are willing to spend more money on the original drug in order to ensure the curative effect. Aspirin was originally used as a medicine.
