Abstract: Objective To evaluate prospectively the adverse reactions of cefazolin sodium pentahydrate for injection and evaluate its safety by means of the Chinese Hospital Pharmacovigilance System (CHPS). Methods From March 1, 2018 to October 31, 2018, the data on 3 641 valid hospitalized patients was collected prospectively via the CHPS from six tertiary hospitals, and the post-marketing safety analysis of cefazolin sodium for injection was performed. Results The rate of adverse drug reactions (ADR) was 4.35‰. There were no serious ADR, and most of the ADR occurred within 24 hours of the administration. The drug was discontinued after the occurrence of ADR. Some patients received treatment after the discontinuation of this drug. All the patients were cured or improved after treatment. Conclusion The incidence of ADR (4.35‰) of cefazolin sodium pentahydrate for injection is significantly different from that of ADR (1.1%) in the instructions for amorphous cefazolin sodium. Probably due to the chelating structure of unstable cefazolin sodium pentahydrate, the sulfur-containing groups in the tunnel-shaped cavity protective molecules composed of cefazolin molecules will not easily fall off and can avoid contact with rubber plugs, thus improving stability, decreaseing catabolites and reducing adverse reactions.
