A new validated bio-analytical liquid chromatographic-tandem mass spectrometric (LC-MS/MS) method for the quantification of Azithromycin in human plasma

Abstract

A simple, rapid and sensitive LC-MS/MS method was developed and validated for the quantification of azithromycin (AZI) in human plasma. Sildenafil citrate was used as an internal standard. The analytes were extracted from human plasma samples by liquid-liquid extraction technique. The reconstituted samples were chromatographed on a reversed -phase column C18, 50 × 2.1 mm, 5 µm from Waters, by using a 80:20 (v:v) mixture of acetonitrile and 0.1% formic acid in water as the mobile phase at a flow rate of 0.5 mL…
