How many Pfizer patented drugs are there?

The two are only different in processing technology and the quality is guaranteed. Dalian Pfizer Amlodipine Benzenesulfonate Tablets (clorofloxacin) is a patented product, which generally has a certain protection period (other manufacturers are not allowed to stop it during the protection period). The patent protection period of Pfizer amlodipine besylate tablets (clorofloxacin) expired last year, so there are a large number of prevention and treatment products on the market now. Of course, the prevention and control ability of Chinese enterprises is recognized, and the quality is definitely no problem. Because antihypertensive drugs are long-term drugs, it depends on your personal economic ability. Cloroxacin is more expensive than domestic products, so general drug resistance does not need to be put into research and development.
