abstract

  • PURPOSE: The stability of ranitidine syrup re-packaged in unit-dose containers was studied. METHODS: Oral ranitidine hydrochloride syrup containing 16.8 mg/mL of ranitidine hydrochloride (equivalent to 15 mg of ranitidine) in original bulk containers and re-packaged in unit-dose amber-colored glass bottles sealed with aluminum caps were obtained from commercial sources. For extended-stability determinations, samples were stored for 52 weeks at 25 degrees C and 40% relative humidity and analyzed at 0, 4, 13, 26, 39, and 52 weeks. For accelerated stability determinations, samples were stored for 13 weeks at 40 degrees C and 25% relative humidity and analyzed at 0, 4, 9, and 13 weeks. Stability was assessed using high-performance liquid chromatography and by measuring changes in pH and sample weight. The principal impurity and total impurities were also measured. RESULTS: No significant changes in pH were demonstrated, and all values remained well within acceptable limits. The weight change in samples was greater for re-packaged samples stored in accelerated conditions compared with that of samples in the original packaging; however, the differences were not significant. Ranitidine hydrochloride samples in both types of packaging remained stable when stored at 25 degrees C and 40% relative humidity for 52 weeks and at 40 degrees C and 25% relative humidity for 13 weeks. The impurity profiles remained within acceptable limits for all samples. CONCLUSION: Re-packaged ranitidine syrup was stable for up to 52 weeks when stored at 25 degrees C and 40% relative humidity and for up to 13 weeks when stored at 40 degrees C and 25% relative humidity.
