Its metabolism is primarily dependent on cytochrome P450 (CYP) 3A4. Here, the influence of rifampicin, a potent inducer of CYP3A4 and CYP2C19 inducer, moderate inducer of CYP1A2, CYP2B6, CYP2C8, and CYP2C9, and inhibitor of P-gp, on the pharmacokinetics of globalagliatin, were investigated in healthy Chinese subjects.</p>\u0000 <p><b>Methods:</b> This single-center, open-label, one-sequence investigation was performed over 22 days in 24 healthy Chinese volunteers. The volunteers were given single oral doses of 80 mg of globalagliatin on Days 1 and 15 on an empty stomach, while rifampicin 600 mg was given orally once a day from Days 8–21 before breakfast. Blood samples were collected at 0 h (1 h before globalagliatin administration on Days 1 and 15) and at 0.5, 1, 2, 3, 4, 5, 6, 8, 12, 24, 48, 72, 96, 120, and 168 h after dosing to monitor the globalagliatin pharmacokinetic parameters. Blood samples on Day 8 were collected before rifampicin administration. The plasma levels of globalagliatin were assessed using LC-MS/MS. Pharmacokinetic parameters were calculated using Phoenix WinNonlin Version 8.3.3 and analyzed with SAS Version 9.4. Continuous monitoring was performed to assess drug safety and tolerance.</p>\u0000 <p><b>Results:</b> Analysis of the effect of rifampicin on globalagliatin pharmacokinetics in 24 healthy participants showed that with rifampicin, the C_max of globalagliatin decreased by 88.9%, while the AUC_0–t and AUC_0–∞ values were reduced by 97.0% and 96.4%, respectively. The geometric mean ratios of globalagliatin C_max, AUC_0–t, and AUC_0–∞ and their 90% CI values were 11.09% (90% CI:9.40–13.10%), 2.96% (90% CI:2.59–3.39%), and 3.60% (90% CI:3.20–4.04%), respectively.

A vancomycin 24-h steady-state area under the concentration–time curve/minimum inhibitory concentration (AUC/MIC) of ≥ 400 has been associated with positive clinical outcomes, while an AUC/MIC &gt; 600–700 has been associated with increased risk of nephrotoxicity. The 2009 vancomycin dosing guidelines recommended target trough concentrations between 10–20 mcg/mL depending on infection; however, recent pharmacokinetic data suggest that most patients can achieve target AUC/MIC with trough concentrations &lt; 15 mcg/mL.

The MTT test showed HT29 cells were more sensitive to <i>P. farcta</i> extract than <i>D. stramonium,</i> especially at 200 μg/mL concentration.</p>\u0000 <p><b>Conclusion:</b> The findings demonstrate that ethanolic extracts of <i>P. farcta</i> and <i>D. stramonium</i> exhibit significant antibacterial activity, particularly against <i>S. aureus</i>, while also effectively disrupting bacterial biofilms. These results suggest that these extracts possess considerable potential as alternative therapeutic agents against drug-resistant bacterial infections. Further investigation is warranted to elucidate the specific mechanisms of action and to explore their efficacy in clinical applications.</p>\u0000 </div>","PeriodicalId":15381,"journal":{"name":"Journal of Clinical Pharmacy and Therapeutics","volume":"2025 1","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/jcpt/4815952","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143698902","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}
