Abstract
In this study, a sensitive, simple, and reliable HPLC method for quantification of pregabalin in human plasma was developed and validated. 1-Fluoro-2,4-dinitrobenzene was used as precolumn derivatization agent. For chromatography, an analytical reversed phase (C18) column and a mixture of Na2HPO410 mM (pH 8.0)—methanol (35 : 65 v/v) were used as stationary and mobile phase, respectively. Detection was performed using a UV detector tuned at 360 nm. The linearity of the method was tested over the concentration range 1–4500 ng/mL in 500 μL of human plasma and satisfactory results were obtained (r2> 0.999). The method showed good precision and accuracy in terms of within—between days relative standard deviations and percent deviation from nominated values (in the range of 4.3–12.7% and 2.6–8.0%, resp.). The limit of quantification of the method was found to be 1 ng/mL which is better than previously reported method and indicates its potential application for sensitive bioanalysis.
