The purpose of the present work was to validate an accurate and precise high-performance liquid chromatography (HPLC) method involving ultraviolet detection for the quantitative analysis of memantine hydrochloride. In order to analyze a molecule with no chromophoric groups that could be detected by a UV/visible detector, it was necessary to extract the drug and to perform a dansylation reaction that enabled the UV/visible detection of the derivatized molecule. Separation was carried out with a 150 mm Kromasil C18 column at room temperature. The detection response, at 218 nm, was found to be linear in the concentration range from 0.5 to 50 μg/mL. The method was validated for specificity, linearity, precision, accuracy, limit of detection, limit of quantification, and robustness. The limit of detection (LOD) was 0.144 μg/mL, and the limit of quantification (LOQ) was 0.437 μg/mL. The dansylated memantine complex was stable for at least five days in all the conditions evaluated. The potential use of this method has been demonstrated by the quantification of memantine hydrochloride contained in samples from the study of itsin vitrotransdermal permeation.

In this study, a high-performance liquid chromatographic method (HPLC) was developed, validated and applied for the determination of raltegravir in biological sample like saliva. Liquid- liquid extraction was performed for isolation of the drug and elimination of saliva interferences. Samples of saliva was extracted with 50µL of ortho phosphoric acid and 3ml of methanol was added and spiked with raltegravir. The chromatographic separation was performed on Agilent Eclipse C18 (100 mm × 4.6 mm, 3.5µm) column, by using 80:20 v/v acetonitrile: water as a mobile phase under isocratic conditions at a flow rate of 1.0 mL/min for UV detection at 240 nm. Retention time of raltegravir was found to be 1.030 min. Linearity was found to be in the range of 25-1000 ng/mL with regression equation y = 13864x + 40495 and correlation coefficient 0.999. The low % RSD value indicates the method is accurate and precise. The limit of detection (LOD) and limit of quantification (LOQ) were found to be 0.76 and 2.28 ng/mL, respectively. It can be concluded that this validated HPLC method is easy, precise, accurate, sensitive and selective for determination of raltegravir in saliva.

The analysis was carried out usingInertsil ODSC18(4.6 x 150 mm, 5μm) column, and the separation was carried out using a mobile phase containing a buffer of pH 3.5 and acetonitrile (70:30 v/v) pumped at a flow rate of 1.0 mL/min with variable wavelength UV-detection at 224 nm. Both the drugs were well resolved in the stationary phase and the retention times were 2.350 min and 4.055 for levamisole and albendazole, respectively. The method was validated and shown to be linear in the concentration range of 15-45μg/ml and 40-120μg/ml for levamisole and albendazole, respectively. The limit of detection (LOD) and limit of quantification (LOQ) were determined based on standard deviation of the y-intercept and the slope of the calibration curve. LOD and LOQ values were 2.08μg/ml and 6.03μg/ml for levamisole and 3.15μg/ml and 10.40μg/ml for albendazole, respectively.
