| 1 | The transport activities (Vmax/Km) of famotidine (Km, 345 microM) by rOat3 were 8- and 15-fold lower than those of cimetidine (Km, 91 microM) and ranitidine (Km, 155 microM), respectively, whereas the activity by hOAT3 (Km, 124 microM) was 3-fold lower than that of cimetidine (Km, 149 microM) but similar to that of ranitidine (Km, 234 microM). | Famotidine | solute carrier family 22 member 8 | Rattus norvegicus |
| 2 | The transport activities (Vmax/Km) of famotidine (Km, 345 microM) by rOat3 were 8- and 15-fold lower than those of cimetidine (Km, 91 microM) and ranitidine (Km, 155 microM), respectively, whereas the activity by hOAT3 (Km, 124 microM) was 3-fold lower than that of cimetidine (Km, 149 microM) but similar to that of ranitidine (Km, 234 microM). | Cimetidine | solute carrier family 22 member 8 | Rattus norvegicus |
| 3 | The transport activities (Vmax/Km) of famotidine (Km, 345 microM) by rOat3 were 8- and 15-fold lower than those of cimetidine (Km, 91 microM) and ranitidine (Km, 155 microM), respectively, whereas the activity by hOAT3 (Km, 124 microM) was 3-fold lower than that of cimetidine (Km, 149 microM) but similar to that of ranitidine (Km, 234 microM). | Ranitidine | solute carrier family 22 member 8 | Rattus norvegicus |
| 4 | Comparison of the relative transport activity with regard to that of cimetidine suggests that famotidine was more efficiently transported by hOAT3 than rOat3, and vice versa, for ranitidine. | Famotidine | solute carrier family 22 member 8 | Rattus norvegicus |
| 5 | These results suggest that, in addition to the absence of OCT1 in human kidney, a species difference in the transport activity by hOAT3 and rOat3 accounts, at least in part, for the species difference in the drug-drug interaction between famotidine and probenecid. | Famotidine | solute carrier family 22 member 8 | Rattus norvegicus |
| 6 | These results suggest that, in addition to the absence of OCT1 in human kidney, a species difference in the transport activity by hOAT3 and rOat3 accounts, at least in part, for the species difference in the drug-drug interaction between famotidine and probenecid. | Probenecid | solute carrier family 22 member 8 | Rattus norvegicus |
