Pfizer has recalled several injection drugs with glass particles, but none of them have entered the Chinese market. The official website of the US Food and Drug Administration (FDA) recently issued two notices, stating that Pfizer has voluntarily recalled products such as 4.2% sodium bicarbonate injection, 8.4% sodium bicarbonate injection, atropine sulfate injection, and bleomycin for injection, due to the presence of glass particles in the aforementioned products. The website of the National Medical Products Administration shows that none of Pfizer's above-mentioned drugs have entered the domestic market.
