Biosynthesis of Salbutamol-4′-O-sulfate as Reference for Identification of Intake Routes and Enantiopure Salbutamol Administration by Achiral UHPLC-MS/MS
نویسندگان
چکیده
The aim of the study was a comprehensive and quantitative determination salbutamol its sulfoconjugated major metabolite in urine samples using achiral ultrahigh performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS). Therefore, salbutamol-4′-O-sulfate biosynthesized as reference genetically modified fission yeast cells, product subsequently characterized by NMR HRMS. In competitive sports, is classified prohibited drug; however, inhalation at therapeutic doses permitted with maximum allowance 600 µg/8 h. contrast, enantiopure levosalbutamol under any condition. For analytical discrimination, amount main excreted studied. As proof concept, longitudinal one healthy volunteer performed order to investigate amounts potential discrimination chromatography. Discrimination administration racemic or not achieved solely analyzing parent compound. However, distinction possible evaluation proportion relation salbutamol. material metabolites great importance doping control, especially for threshold substances.

An aerosol formulation containing 7.5 mg of R-salbutamol sulfate was developed. The aerosol was nebulized with an air-jet nebulizer, and further assessed according to the new European Medicines Agency (EMA) guidelines. A breath simulator was used for studies of delivery rate and total amount of the active ingredient at volume of 3 mL. A next generation impactor (NGI) with a cooler was used for ...

This study was conducted to determine whether small doses of salbutamol solution, aerosolised and delivered by intermittent positive-pressure breathing (IPPB), would be as effective as the 5 to 10 mg dose usually recommended for inhalational use. In nine asthmatic subjects we found that there was no significant difference between the peak bronchodilator effect of 1.0, 2.5, and 5.0 mg of salbuta...
