Aspirin Bay refers to aspirin enteric-coated tablets, which are not very different from aspirin extended-release tablets in terms of medication effects, and there is no such thing as which one is better. Both aspirin enteric-coated tablets and aspirin extended-release tablets belong to the aspirin group of drugs, only the type of preparation is different. Both have the effect of inhibiting platelet aggregation and preventing thrombosis. They are commonly used in the prevention of transient cerebral ischemia, myocardial infarction, atrial fibrillation, etc. They can also be used in unstable angina pectoris. Aspirin enteric-coated tablets are mainly absorbed through the intestinal tract, with less irritation to the stomach, while aspirin extended-release tablets mainly control the absorption and metabolism of aspirin, so as to make its balanced distribution and maintain it for a longer period of time. Aspirin may have adverse reactions such as epigastric discomfort, indigestion and nausea after use. Patients should choose the appropriate medication for use in their own situation under the guidance of their doctor, observe the effect of the medication, and communicate with their doctor in time so that adjustments can be made.
