Coadministration of the xanthine oxidase inhibitor, febuxostat, in patients receiving methotrexate has been reported to be associated with an elevated risk of hematological toxicity and increased plasma methotrexate levels. Because febuxostat has an inhibitory effect against hOAT3, it may inhibit renal elimination of methotrexate via hOAT3. However, the drug interaction between methotrexate and febuxostat via hOAT3 remains to be clarified. In the present study, we investigated the effect of febuxostat on pharmacokinetics of methotrexate in rats and drug interaction between methotrexate and febuxostat using hOAT3-expressing cultured cells. In the pharmacokinetics study using rats, concomitant administration of febuxostat significantly increased plasma concentration of methotrexate and prolonged its half-life. In vitro studies showed that febuxostat inhibited hOAT3-mediated transport of methotrexate in a concentration-dependent manner. Dixon plot indicated that inhibitory constant value of febuxostat against methotrexate transport via hOAT3 was 0.63 ± 0.01 μM. Moreover, the inhibitory effect of febuxostat was of noncompetitive type. Taken together, these results suggest that concomitant administration of febuxostat delayed elimination of methotrexate, at least in part, by noncompetitive inhibition of hOAT3-mediated methotrexate transport at clinical concentrations. The findings of this study provide novel information on drug interactions associated with febuxostat.","PeriodicalId":8865,"journal":{"name":"Biopharmaceutics & Drug Disposition","volume":"46 4","pages":"165-171"},"PeriodicalIF":2.0,"publicationDate":"2025-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/bdd.70014","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144940733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, Sprague–Dawley rats were randomly assigned to three groups: a control group, a single-dose group (50 mg/kg of α-MG), and a multiple-dose group (50 mg/(kg/d) of α-MG for 7 days). Tofacitinib (10 mg/kg) was administered 30 min after the intervention of α-MG to each group. The plasma was collected from the caudal vein at different time points and in heparinized tubes. Tofacitinib metabolites in the plasma were determined by UPLC-MS/MS. Further analyses were conducted utilizing Pymol molecular docking simulation to evaluate the effect of α-MG on tofacitinib. Our results showed that MG inhibited the metabolism of tofacitinib in vitro by exhibiting both competitive and noncompetitive inhibition. More importantly, we found that multiple-dose administration of α-MG significantly increased the AUC(0–12h), AUC(0–∞), and Cmax, prolonged the t1/2 and shortened the MRT(0–12h) and MRT(0–∞) of tofacitinib. At the same time, the CLz/F was decreased, which was consistent with the results of in vitro experiments. Furthermore, we observed no significant difference between single-dose and multiple-dose groups. Intriguingly, α-MG and tofacitinib were close at the CYP3A4 spatial location. In summary, our investigation demonstrated that α-MG significantly impacts the metabolism of tofacitinib both in vitro and in vivo, suggesting potential herb–drug interactions (HDIs).

Pharmacodynamics indexes of all treatment groups were significantly improved. There was no significant difference between AC group and combination group except HDL-C, SOD and liver index. In conclusion, CURs combined with atorvastatin could not effectively enhance the lipid-lowering effect or alleviate liver damage.

Although Almonertinib is commonly prescribed in combination with MgIG in clinical application, the interaction research between them has not been reported. This research was conducted to explore the influences of MgIG on the pharmacokinetics of Almonertinib in rats and to investigate its possible molecular mechanisms.

Furthermore, MgIG can markedly down-regulate the expression levels of CYP3A1 and P-gp in rat livers. There is a drug–drug interaction (DDI) between MgIG and almonertinib, which leads to an increase of systemic exposure for almonertinib. Meanwhile, CYP3A1 and P-gp in the liver may be the primary targets of mediating the DDI, but further clinical trials are needed to confirm these results.\u0000 </div>","PeriodicalId":8865,"journal":{"name":"Biopharmaceutics & Drug Disposition","volume":"46 3","pages":"95-103"},"PeriodicalIF":2.0,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143959346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Full-length IgG and Fab fragments were intravenously administered in UUO-induced renal fibrosis model mice.

Both full-length IgG and Fab fragments showed higher distribution in fibrotic kidneys than in other organs. Specifically, Fab fragments had excellent selective accumulation in the fibrotic kidneys, whereas full-length IgG had higher absolute distribution due to slower plasma elimination. Imaging assessments revealed that both had widespread localization within the interstitial spaces of the fibrotic kidneys. Due to their superior selectivity for fibrotic kidneys, Fab fragments can be used to target fibrotic lesions. Due to its prolonged distribution, full-length IgG may offer advantages in sustained therapeutic effects.

Rats with depression exhibited a significant increase in maximum plasma concentration (Cmax).

On the one hand, rats with gastric ulcers displayed a significant decrease in Cmax, coupled with an extended time to reach maximum plasma concentration (Tmax), prolonged t1/2, MRT, and increased volume of distribution (Vd) of encorafenib.
