Abstract
The liquid chromatography–tandem mass spectrometry (LC-MS)/MS methodology was used to develop and validate a method for detecting erythromycin and olaparib in human plasma. Antibiotics such as erythromycin and olaparib fall into this category. Liquid chromatography is used to separate stationary and mobile phases based on differences in their affinities as well as to remove unwanted contaminants. It improves repeatability, sensitivity, resilience, and low-level protein detection. A C18 (C18, 5 m, 100×4.6 mm) column is utilized for high resolution and peak area. The calibration curve is created using linear regression. Internally, telmisartan is utilized as a benchmark. The flow rate of the mobile phase is 0.5 mL/min. Erythromycin and olaparib have mass-to-charge ratios of 735.43–115.97 and 435.08–102.04, respectively. Erythromycin in combination with olaparib resulted in a 98% recovery rate. The precision and accuracy of the results determined by interday QC samples are within acceptable limits. There was no evidence of instability.
