Abstract

A rapid and sensitive high performance liquid chromatographic (HPLC) method was developed and validated for the analysis of venlafaxine (VEN) and O‐desmethylvenlafaxine (ODV) in human plasma. The analytes were extracted from human plasma by using liquid–liquid extraction technique. Citalopram (CTP) was used as the internal standard. A Zorbax XDB C‐18 column provided chromatographic separation of analytes followed by UV detection with wavelength at 229 nm. The linear range for both analytes was 5 ng/mL to 1000 ng/mL with precision and accuracy of <10%. Total elution time was 12 min.
