Abstract
A simple, specific, accurate, and stability indicating high-performance
liquid chromatographic method was developed for the determination
of Ramosetron HCl, using a Enamel C18 column and a mobile phase
composed of Methanol:Water (50:50). The retention time of
Ramosetron HCl found to be 3.59 min. Linearity was established for
of Ramosetron HCl in the range of 200-600 ng/ ml. The percentage
recoveries of was found to be in the range of 98.33-98.86 %. The drug
was subjected to acid and base hydrolysis, oxidation, photolytic, and
thermal degradation conditions. The degradation products of
Ramosetron HCl were well resolved from the pure drug with
significant differences in their retention time values. This method can be successfully
employed for quantitative analysis of Ramosetron HCl in pure and tablet.
Keywords: Ramosetron HCl, degradation products, stability - indicating method, HPLC.
