The high incidence of resistance to this drug requires efforts to increase the effectiveness of TB therapy. Immunomodulator supplementation is one effort to overcome this problem. Phyllanthus niruri has an immunomodulating effect, which has been proven to influence the clinical improvement of the immunological profile. However, the effect of this plant on rifampicin's bioavailability should be reviewed to determine potential changes that may affect its antibacterial performance. Several stud-ies have shown an increase in the bioavailability of rifampicin when administered with extracts and active isolates of Carum carvi, Cuminum cyminum, Piper nigrum, and Moringa oleifera through inhibition of the P-gp efflux function in the absorption phase. On the other hand, the decrease occurred in coadministration with Garcinia cola, which activated PXR action and subsequently changed P-gp regulation. Administration of Al-lium sativum and Zingiber officinale extracts did not show significant alteration in bioavailability due to the stimulation of several mechanisms with opposite outputs by each secondary metabolite. In the case of P. niruri supplementation, the potential for a rise in bioavailability could occur due to synergistic effects inhibiting the performance of P-gp, AADAC, and OATP1B. However, the stimulation of PXR and PPARα may reduce or eliminate these effects. Finally, considering that there are so many specific secondary metabolites in P. niruri whose effects on the performance of these functional proteins have not been exposed, in vivo studies are needed to confirm the interactions within complex biological systems.</p>","PeriodicalId":10770,"journal":{"name":"Current drug metabolism","volume":" ","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143398535","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}

The clinical response to venetoclax exhibits heterogeneity, and its sensitivity and resistance may be intricately linked to genetic expression. Pharmacokinetic studies following doses of venetoclax (ranging from 100 to 1200mg) revealed a time to maximum observed plasma concentration of 5-8 hours, with a maximum blood concentration of 1.58-3.89 μg/mL, and a 24-hour area under the concentration-time curve of 12.7-62.8 μg·h/mL. Population-based pharmacokinetic investigations highlighted that factors such as low-fat diet, race, and severe hepatic impairment play pivotal roles in influencing venetoclax dose selection.

Cytochrome P450 (CYP 450) isoforms are responsible for the metabolism of many features associated with food parameters like phytochemicals, juices, and fruits. This review article summarizes the findings of previous studies to help predict the efficacy or side effects of tacrolimus in the presence of food variables. From the commencement of databases associated with the topic of interest to 26 October 2024, all relevant articles were searched through PubMed, Scopus, and Web of Science. The suggested therapeutic range for tacrolimus trough concentration (C₀ ) was reported as 5-15 ng/ml blood. Tacrolimus interaction with food variables could significantly change C₀ after organ transplantation. For example, grapefruit juice could increase tacrolimus C₀ due to CYP enzyme inhibition. Toxicity such as nephrotoxicity could result from turmeric and other herbal or food products. By inhibiting tacrolimus-metabolizing enzymes and transporters, a high intake of vegetables could increase the risk of adverse effects. Secondary metabolites of vegetables could lead to toxicity in patients with tacrolimus. Furthermore, grapefruit juice, citrus fruits, turmeric, and pomegranate juice could change clinical pharmacokinetics parameters such as T_max, C_max, AUC, and C₀ of tacrolimus after organ transplantation. Bioavailability of tacrolimus might be decreased by induction of the CYP450 system and P-gp efflux pump due to cranberry, rooibos tea, and boldo. Increased inhibitory effect on CYP450 system and/or P-gp efflux pump by grapefruit juice, schisandra, berberine, turmeric, pomegranate juice, pomelo, and ginger could increase bioavailability of tacrolimus.
