Based on oral administration studies, its International Screening Limit (ISL) was established in plasma and urine at 1 ng/mL with a Detection Time (DT) of 48 h. A novel formulation of injectable omeprazole has since been released, and therefore, a pharmacokinetic study was performed to assess the DT above the ISL against current advice. Six Thoroughbred horses were given four repeated weekly intramuscular administrations of omeprazole (4 mg/kg). Plasma and urine omeprazole concentrations were measured by liquid chromatography–tandem mass spectrometry. Based on the current plasma and urine ISL (1 ng/mL), the DT for this long-acting omeprazole formulation administered at 4 mg/kg once per week is greater than 384 h (16 days) in both plasma and urine. Thus realistically, despite the appeal of giving an injection once per week rather than oral medication daily over a long period of time, this would make treatment for horses in training with the long-acting product challenging within the rules of racing. It would therefore most likely be used for horses outside of training, and the oral formulation would still be legitimately used during training.</p>","PeriodicalId":17596,"journal":{"name":"Journal of veterinary pharmacology and therapeutics","volume":"48 3","pages":"155-162"},"PeriodicalIF":1.5,"publicationDate":"2025-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jvp.13494","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143374444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

That PK/PD relationship, along with the population variability in drug exposure, is used to determine the probability of target attainment (PTA) of the PK/PD index at a specified minimum inhibitory concentration (MIC) for a selected target value. The PTA is used to identify the pharmacodynamic cutoff value (CO<sub>PD</sub>), which is one of the three components used to establish the clinical breakpoint. A challenge encountered when defining the CO<sub>PD</sub> is that the available PK information typically reflects total (free plus protein-bound) plasma concentrations. However, it is the unbound drug concentrations that exert the therapeutic effects and how the population fraction unbound (<i>fu</i>) incorporated into the CO<sub>PD</sub> assessments can markedly influence the CO<sub>PD</sub>. Factors examined included the estimated population <i>fu</i> mean (risk of bias) and the incorporation of estimated <i>fu</i> population variability into the Monte Carlo simulations when converting total to unbound plasma concentrations (risk of inflating variability).
