Materials & methods: Oral and intravenous dose studies were conducted in rats and mice. Significant intersex differences were observed in peak plasma levels of metoprolol after oral dose in both the species. The plasma concentration (Cmax) was approximately sevenfold higher (270.356 ng/ml) in female compared with male rats (40.981 ng/ml) following oral dose administration. The Cmax observed for male (878.822 ± 75.5 ng/ml) was approximately twofold higher than in female mouse (404.016 ± 113.5 ng/ml) after oral dose administration. Conclusion: Sex and species related physioanatomical characteristics alters metoprolol pharmacokinetics. Such differences should be addressed in studies related to metoprolol interactions with concurrently administered drug candidates.","PeriodicalId":73468,"journal":{"name":"International journal of pharmacokinetics","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84264926","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Current antibiotic regimens, constructed prior to the development of modern pharmacokinetic-pharmacodynamic (PK-PD) tools, are based on incomplete understanding of exposure-response relationships in drug susceptible and multidrug resistant tuberculosis.

Future clinical PK-PD challenges include: incorporation of PK methods to assay free concentrations for all active metabolites; selection of appropriate early outcome measures which reflect therapeutic response; elucidation of genetic contributors to interindividual PK variability; conduct of targeted studies on special populations (including children); and measurement of PK-PD parameters at the site of disease.</p>","PeriodicalId":73468,"journal":{"name":"International journal of pharmacokinetics","volume":"2 3","pages":"195-212"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.4155/ipk-2017-0004","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36544898","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
