Quantification of fluticasone propionate in human plasma by LC-MS/MS and its application in the pharmacokinetic study of nasal spray at clinical doses
Drug Metab Pharmacokinet. 2023 Dec 11;54:100541. doi: 10.1016/j.dmpk.2023.100541. Online ahead of print.ABSTRACTWe developed a method for quantifying fluticasone propionate (FP) using general-purpose liquid chromatography-tandem mass spectrometry equipment to measure the plasma concentration of FP for the pharmacokinetic study of FP following the administration of a prescribed nasal spray dose (100 μg). Using ammonium acetate (0.01 M)-formic acid (pH 2.9; 499:1, v/v) and methanol as the mobile phase, 3 pg/mL of FP was quantified. The relative error and standard deviation of the lower limit of quantification were <3.1%....

Giant lung cavity due to three different pathogens in a patient receiving inhaled salmeterol plus fluticasone propionate for asthma
CONCLUSION: Tuberculosis and other opportunistic infections are a potential consequence of inhaled corticosteroid use. Clinicians overseeing such patients need to be vigilant about the need for timely investigations about tuberculosis before and during prescribing medications containing inhaled corticosteroids.PMID:38078667 | DOI:10.1080/02770903.2023.2293069 (Source: Journal of Asthma)
