The crucial endeavor in this method is focused on the study analysing recovery and column efficiency (theoretical plate) after extraction of metoclopramide from PVP K30-Metoclopramide (3:1 w/w) solid dispersion (SD). The proposed work also presents a reversed-phase high performance liquid chromatography method for the detection of very small amount of metoclopramide base followed by different analytical techniques. In this context, it may be noted that the values of limit of detection (LOD) and limit of quantitation (LOQ) for the metoclopramide base as obtained are, 0.052 μg/mL and 0.159 μg/mL respectively. The linearity is performed in the range of 2-20 μg/ mL; performance of column remained satisfactory throughout the analysis, N = 4927-2434. The percentage recovery of pure and extracted metoclopramide ranges from 103-105% and 86-120% approximately. The results collectively demonstrate that the proposed method is selective. Clear isolation of metoclopramide from SD is achieved without any solid state interference.
