Clinical Drug-Drug Interactions

DDI Implicated Transporter* Interacting Drug Affected Drug AUC Cmax CLR CL/F t1/2 Effect on PD Reference More Details
Clinical PK Impact(fold change)
1 OATs Probenecid Ceftriaxone 0.7 ND ND 1.3 0.8 ND Stoeckel, 1988 DDI 1

PK = pharmacokinetic
The transporters are implicated by in vitro data and/or studies in humans with genetic polymorphisms of the transporter
DDI = Drug Drug Interaction
PD = pharmacodynamic
ND = not determined
NS = not significant
N/A = information not available
Calculation of Fold Change: fold change in the presence of the interacting drug = (value with interacting drug)/(value without interacting drug)
fold change > 1: increase in pharmacokinetic value
fold change < 1: decrease in pharmacokinetic value
