“…PK/PD approaches also allow evaluating potential drug–drug interactions and identifying the PK and/or PD parameters affected. Van den Berg et al63 identified by PK/PD modeling that the interaction between formoterol and theophylline with regard to their eosinopenic and hypokalemic effects was limited to a noncompetitive PD interaction, whereas PK remained unaffected. Belani et al64 identified by PK/PD correlation that in the absence of any PK interaction, paclitaxel has a platelet‐sparing effect on the dose‐limiting thrombocytopenia of carboplatin during the combination therapy of both drugs in patients with non‐small‐cell lung cancer.…”

“…The estimates of the population PK parameters for the final PK model, their BSV% and RSE% values are listed in Table C.3.8. A high absorption rate constant (kL = 14.8 h -1 ) was estimated for FOR, which is in accordance with the small Tmax values (5-10 min) observed in the non-compartmental analysis, while the apparent volumes of distribution for the central (Vc/F = 619 L) and the peripheral compartments (Vp/F = 1,130 L) were in line the moderately lipophilic character of the drug and in agreement with previously reported values (Derks et al, 1997;van den Berg, 1999). Clearance of the drug from the central compartment (CL/F = 93 L/h) was determined to be somewhat smaller compared with other reported values (Derks et al, 1997), which may be partly explained by the addition of fecal elimination contributing to the total clearance of the drug.…”

“…The accurate prediction of DDIs can be complex as there are many factors that may be contributing to the observed changes . These include induction or inhibition of metabolic enzymes drug induced physiological alterations such as changes in hepatic blood flow or cardiac output, the involvement of transporters changes in absorption and antagonism/enhancement of pharmacological effect …”
