ABSTRACT
Simvastatin (SIM) is known to lower cholesterol levels and is speculated in the pathogenesis of Alzheimer's disease. In this study, the bioanalytical method of SIM SNEDDS was developed and validated for the estimation of SIM in the rat's plasma using reverse-phase high-performance liquid chromatography. C-18 reverse-phase octadecylsilyl column was used to validate the method. Atorvastatin (ATV) was used as an internal standard. Gradient elution was performed using acetonitrile and water in a ratio of 9010 with a flow rate of 1 mL/min. The chromatogram of these both compounds SIM and ATV was detected at a wavelength of 238 and 244 nm. The drugs were extracted from the plasma samples using the protein precipitation method. The retention time of SIM and ATV was found to be 3.720 and 8.331 min, respectively. The developed method was found to be linear in the range between 50 and 250 ng/mL, with a regression coefficient (r2) of 0.9994. According to ICH M10 guidelines, the method was validated. The percent of drug recovery was more than 95% and the % relative standard deviation was <2% in the replicate studies, which showed that the method was accurate and precise. The limit of detection and limit of quantification were found in rat plasma to be 0.12 and 0.38 ng/mL, respectively. The obtained result indicated that the developed method was successful in estimating SIM in rat plasma and passed all validation test parameters.
