Table 2. Examples of DDI definitions.

PMID DDI sentence Relationship and commend
20012601 The pharmacokinetic parameters of verapamil were significantly altered by the co-administration of lovastatin compared to the control Because of the words, “significantly,” (verapamil, lovastatin) is a DDI
20209646 The clearance of mitoxantrone and etoposide was decreased by 64 and 60 %, respectively, when combined with valspodar Because the fold changes were less than 0.67 (mitoxantrone, valspodar) and (etoposide, valspodar) are DDIs
20012601 The (AUC (0-infinity)) of norverapamil and the terminal half-life of verapamil did not significantly changed with lovastatin co-administration Because of the words, “not significantly changed,” (verapamil, lovastatin) is an NDDI
17304149 Compared with placebo, itraconazole treatment significantly increases the peak plasma concentration (Cmax) of paroxetine by 1.3-fold (6.7 ±2.5 versus 9.0 ±3.3 ng/mL, p≤ 0.05) and the area under the plasma concentration–time curve from zero to 48 h (AUC(0–48)) of paroxetine by 1.5-fold (137 ±73 versus 199 ±91 ng×*h/mL, p≤0.01) AUC has a higher rank than Cmax, and it had a 1.5-fold change and less than 0.05 p-value; thus, (itraconazole, paroxetine) is a DDI
13129991 The mean (SD) urinary ratio of dextromethorphan to its metabolite was 0.006 (0.010) at baseline and 0.014 (0.025) after St John's wort administration (p= 0.26) The change in PK parameter is more than 1.5-fold but p-value is >0.05. Thus, (dextromethorphan, St John's wort) is an ADDI
19904008 The obtained results show that perazine at its therapeutic concentrations is a potent inhibitor of human CϒP1A2 Because of the word, “potent inhibitor,” (perazine, CYP1A2) is a DEI
19230594 After human hepatocytes were exposed to 10 μM ϒM758, microsomal activity and mRNA level for CϒP1A2 were not induced while those for CϒP3A4 were slightly induced Because of the words, “not induced” and “slightly induced,” (YM758, CYP1A2) and (YM758, CYP1A2) are NDEIs
19960413 From these results, DPT was characterized to be a competitive inhibitor of CϒP2C9 and CϒP3A4, with K(i) values of 3.5 and 10.8 μM in HLM and 24.9 and 3.5 μM in baculovirus–insect cell-expressed human CYPs, respectively Because Kwzs larger than 10 μM, (DPT, CYP2C9) and (DPT, CYP3A4) are ADEIs
