The correlation coefficient (r) = 0.999 was proved that the method is robust. The resolution between known impurities and Prochlorperazine edisylate found more than 2.5, it was evident from specificity test that Prochlorperazine edisylate peak are well separated from its related impurities, hence the method is specific. Prochlorperazine edisylate sample solution and mobile phase were found to be stable for at least 3 d.

INTRODUCTION

Prochlorperazine edisylate is widely used to treat nausea and vomiting caused by radiation therapy, cancer chemotherapy, surgery and other condition. It has also been used to relieve pain associated with migraine headaches. Prochlorperazine edisylate blocks postsynaptic dopamine receptors in cortical and limbic areas of the brain thereby preventing the excess of dopamine in the brain [1]. It is having chemical name, 2-Chloro-10-[3-(4-methyl-1-piperazinyl) propyl] phenothiazine 1, 2 ethane disulfonate (1:1) [1].

The chemical formula is c20h24cln3s. C2H6O6S2, chemical structures show in (fig. 1), process-related impurities are prochlorperazine sulfoxide, dimer-I, dimer-II and perazine. 2-chlorophenothiazine is starting material of Prochlorperazine edisylate drug substances. In literature there are HPLC method of Simultaneous Quantitation ff Plasma Doxorubicin and Prochlorperazine content By High-Performance Liquid Chromatography [2], quantification of prochlorperazine maleate in human plasma by liquid chromatography–mass spectrometry: application to a bioequivalence study [3].

In the literature, there is no analytical method was reported for rapid assay of prochlorperazine edisylate drug substances using ultra-performance liquid chromatography (UPLC) technique. The UPLC is recent, advanced and rapid chromatographic technique.

This report describes a reverse-phase UPLC method for the assay test for prochlorperazine edisylate on by using Acquity BDH UPLC column C4 (100 x 2.1 mm) 1.7µ. The developed UPLC method was validated for assay determination of prochlorperazine edisylate in drug substance as per validation of analytical procedure guidelines

Solution stability

Solution stability was performed at the room temperature. Test sample was prepared at specification level and injected as fresh, 1 d, 2day and 3day intervals.

Robustness

Robustness of the method was verified by varying the instrumental conditions such as by changing flow rate ± 10% (flow= 0.385 ml/min and 0.315 ml/min) by changing column oven temperature ± 5 °C (temp.= 35 °C and 25 °C) by mobile phase concentration ± 2% (buffer 71+29 acetonitrile and buffer 75+25 acetonitrile) and by changing column lot number. The system suitability was evaluated in each condition and sample was analyzed in triplicate.

CONCLUSION

A new, simple and rapid method is developed and validated by UPLC technique as per ICH guideline. Linearity was obtained with correlation coefficient 0.999. In specificity study, the resolution of known impurity and principal peak found more than 2.5, hence the known impurity found well separated from principal peak. Forced degradation shows all degradants are well separated from principal peak and peak purity was within limit. The results for precision, robustness found comparable and well within the limit. The sample solution, standard solution and system suitability solution are stable up to 3 d.

In literature, there is no analytical method reported for assay determination of Prochlorperazine edisylate drug substances by UPLC. In this method all the known and degrading impurities are well separated within five minute run time, hence the analysis time required is very less as compared to other published methods. The developed method can be used for rapid assay of Prochlorperazine edisylate drug substances in research laboratories, in pharmaceutical industries.
