Ranitidine bismuth citrate_product_DataBase

Bioactivity	Ranitidine bismuth citrate is an orally active Histamine H2-receptor antagonist with an IC50 of 3.3 μM. Ranitidine bismuth citrate has high selectivity for SARS-CoV-2-infected cells. Ranitidine bismuth citrate is a commonly used agent anti-Helicobacter pylori infection with an MIC90 value of 16 ng/L[1][2][3].
Target	IC50: 3.3 μM
Invitro	Ranitidine bismuth citrate (0.1-1 μM, 5 min) is a potent irreversible inhibitor of both the ATPase (IC50=0.69 µM, Ki =0.97 µM ) and DNA-unwinding (IC50 =0.74 µM, Ki =0.39 µM) of the SARS-CoV-2 helicase[2].Ranitidine bismuth citrate (24 hours) shows potent activity against SARS-CoV-2 with an EC50 value of 2.3 μM in Vero E6 cells[2]. Cell Cytotoxicity Assay[2] Cell Line:
In Vivo	Ranitidine bismuth citrate (150 mg/kg; intranasally inoculation; once daily; 4 days) suppresses SARS-CoV-2 replication, and relieves virus-associated pneumonia in a golden Syrian hamster model[2].Ranitidine bismuth citrate (48 mg/kg, i.p.) is effective in eradicating H. pylori and H. mustelae in female ferrests with MIC values of 8 ng/L and 1-2 ng/L, respectively[3].Ranitidine bismuth citrate (0.1 mg/kg, 0.3 mg/kg; p.o.) is effective in inhibiting gastric acid secretion and (1.0 mM) inhibits human pepsin isoenzymes activity[4].
