It can be taken for a long time, and there are a lot of experimental results and papers to support this view (many experiments are done by Bayer Pharmaceuticals, but they are indeed published in more authoritative academic journals). However, as far as the current market is concerned, only the baspirine produced by Bayer Pharmaceutical Factory can achieve accurate enteric dissolution, and domestic pharmaceutical factories can also achieve the expected enteric dissolution to a certain extent, but it is not accurate (there is still the possibility of gastric dissolution).

This kind of accurate enteric dissolution means that drugs can not be dissolved in acidic conditions in the stomach, but only in alkaline environment in the intestine due to some technological innovations and applications.

Accurate enteric coating aims at protecting gastric mucosa. Aspirin is an antipyretic and analgesic drug, and long-term use will really damage the function of the stomach (not to say that enteric coating can eliminate this damage, but to minimize it).

I remember the recommended dosage and usage is one tablet once a day and one tablet every night (please consult your attending doctor for accurate information). A small box is not expensive (it may be cheaper if it is produced by domestic pharmaceutical companies), and if there is medical insurance, it should reduce the money.

If you still don't understand what I just explained, you can continue to ask.

Well, I'm really not Bayer's childcare. ...

The side effects of aspirin can be easily found on the Internet (for example, Baidu Encyclopedia is very detailed), and some patients do have gastrointestinal dysfunction in clinic (but it must be said that antipyretics and analgesics will have this effect, and many antipyretics and analgesics they usually eat will affect the disorder of gastrointestinal system).

However, it depends on the balance between your doctor's advice and yourself.
