The accuracy with the process is indicated by the superb recovery (99.00-101.12 ) plus the precision is supported by the low typical deviation. Table 3 shows that the percent error of the strategy was always less than 1.12 ; consequently, it was concluded that the procedure offers acceptable accuracy and precision for the analyte. robustness. The robustness of an analytical procedure is often a measure of its capacity to stay unaffected by little, but deliberate variations in system parameters and gives an indication of its reliability through regular usage. Robustness in the technique was investigated below many different circumstances including modifications of pH in the mobile phase, flow rate, percentage of methanol in the mobiletable two.

Stability studies had been carried out at laboratory temperature for any month to seek out possible stability troubles in the drug within the formulations. Samples had been analyzed at intervals of 0, 1, 5, 15 and 30 days. The outcomes obtained are given in Table 5. The percent RSD values amongst subsequent readings gave an indication from the stability with the drug within the formulations.Application on the assay The developed technique was applied for the determination of RSP in tablets from the Syrian marketplace. Figure four shows an HPLC chromatogram of RSP in tablets. The outcomes obtained with all the proposed system have been compared together with the official method (11). The outcomes in Table six indicate the higher acc.
