Purpose: The objective of the current study is to evaluate the Ultra Performance Liquid Chromatography (UPLC) method for quantification of Acyclovir in lipid-based formulations.Method: A simple, rapid, reliable and precise reversed phase UPLC method has been developed and validated according to the regulatory guidelines, which composed of isocratic mobile phase; 0.25% formic acid (FA) in Milli-Q water with a flow rate of 0.5 ml/min, and column BEH C18 (2.1 x 50 mm, 1.7 mu m). The detection was carried out at 254 nm.Results: The developed UPLC method was found to be rapid (1.2 min run time), selective with well resoluted Acyclovir peak (0.89 min) from different lipid matrices and sensitive (Limit of Detection (LOD) was 0.3 ppm and Lower Limit of Quantification (LLOQ) was 1 ppm). The accuracy and precision were determined and were perfectly matching with the standard FDA limits.Conclusion: The study showed that the proposed UPLC method can be used for the assessment of drug purity, stability, solubility and lipid-formulation release profile with no interference of excipients or related substances of active pharmaceutical ingredient.
