The efficacy of these two drugs is similar. The content of imported drugs of Polivik is 75 mg per tablet, and that of domestic drugs of Taijia is 25 mg per tablet. However, the price gap is very large. If the economy permits, we can take imported drugs. Now all our hospitals use Taijia, and personally, there is no difference between the effect and the side effects. My mother also made a stent, and after eating it for a year, she has no discomfort now.
