Abstract
AbstractA stability-indicating reverse-phase high-performance liquid chromatography method without the use of a counterion has been developed to quantify ranitidine hydrochloride in pharmaceutical dosage forms. The method is accurate and precise with a percent relative standard deviation of 1.5 based on 5 injections. The extraction procedure for ranitidine from tablets is very simple and there was no interference from the excipients present. Ranitidine appears to be stable to heat on the acidic side and very susceptible to decomposition on the basic side. It lost 84.4% of potency on 20 minute boiling with sodium hydroxide with a new peak in the chromatogram. It lost 37.8% of the potency on treatment with hydrogen peroxide solution for 20 minutes at room temperature with 2 new peaks in the chromatogram.
