Table 5 Representative examples where precipitant and/or object drugs were missed by the model during validation of the 2nd step (named entity recognition to identify precipitant and object drugs)

From: Deep learning-enabled natural language processing to identify directional pharmacokinetic drug–drug interactions

Sentence

True label

Predicted label

Reason for wrong prediction

Barbiturates usually depress griseofulvin activity and concomitant administration may require a dosage adjustment of the antifungal agent

Precipitant: Barbiturates

Object: griseofulvin

Precipitant: None

Object: griseofulvin

Missing precipitant: reason unknown

Potent inhibitors of CYP3A4 can increase the plasma concentrations of budesonide

Precipitant: Potent inhibitors of CYP3A4

Object: budesonide

Precipitant: inhibitors of CYP3A4

Object: budesonide

For precipitant, missing the adjective “potent”

In patients taking ARAVA, exposure of drugs metabolized by CYP1A2 (e.g., alosetron, duloxetine, theophylline, tizanidine) may be reduced

Precipitant: ARAVA

Object: drugs metabolized by CYP1A2, alosetron, duloxetine, theophylline, tizanidine

Precipitant: None

Object: ARAVA, alosetron, duloxetine, theophylline, tizanidine

ARAVA (a precipitant) is mislabeled as object: reason unknown

Missing “drugs metabolized by CYP1A2” as object: not a specific drug name

Intervention: Mycophenolate mofetil (MMF): Co-administration of PPIs in healthy subjects and in transplant patients receiving MMF has been reported to reduce the exposure to the active metabolite, mycophenolic acid (MPA), possibly due to a decrease in MMF solubility at an increased gastric pH

Precipitant: PPIs

Object: Mycophenolate mofetil, mycophenolic acid

Precipitant: PPIs

Object: Mycophenolate mofetil

Missing one object: mycophenolic acid is a metabolite

Caution should be exercised when considering the coadministration of ASMANEX HFA with ketoconazole, and other known strong cytochrome P450 (CYP) isoenzyme 3A4 (CYP3A4) inhibitors (e.g., ritonavir, cobicistat-containing products, atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, saquinavir, telithromycin) because adverse effects related to increased systemic exposure to mometasone furoate may occur

Precipitant: ketoconazole, ritonavir, cobicistat-containing products, atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, saquinavir, telithromycin

Object: ASMANEX HFA, mometasone furoate

Precipitant: missing ketoconazole, ritonavir, and itraconazole

Object: missing ASMANEX HFA

Unknown
